HeishaMon communication print for communication with Panasonic Aquarea H, J, K and L-series heatpumps

The Heishamon software allows your smarthome to communicate with the Panasonic Aquarea heatpump H-series and J-series and now also K-series, L-series (since heishamon firmware v3.2.2) and M-series (since heishamon beta firmware 3.9). replacing the original internet module. It provides MQTT messages, JSON data and API commands for all known values and also provides 1wire DS18b20 and kWh S0 port power metering to provide a complete solution to monitoring the performance of the heatpump. The software also supports to emulate the heatpump optional pcb for two-zone/buffer/swimming pool configurations. You only need to add IOT controlable devices to start waterpumps or open/close valves at (MQTT) requests of the software to use this emulated optional pcb. Send me a message if you need more information about this emulation feature.

The Heishamon software, available from github, can be installed on every ESP8266 or ESP32 board but the communication to and from the heatpump requires some levelshifting. On this PCB the levelshifting is provided and also the connection for 1wire and S0 metering is on the PCB making this HeishaMon board a quick solution to control your heatpump yourself.

The PCB will be delivered as shown on the photo and the latest HeishaMon software will be installed for you. You only need to hook it on to your Panasonic heatpump using the optional cable (see below), configure it using the temporary open wifi hotspot and you can collect the MQTT data it transmits.

The large model (with ESP32-S3 controller) supports extra features like two controlable relays and an ethernet option. To use ethernet, you install a USR-ES1 W5500 module on top of this new model. This module is available on the internet but also as an option in the shop. Also, the large model is designed to fit into a standard ABB-00846 junction box or any other box with at least 10x10x3 cm inner space. You can not order this box here. The smaller model is the one which has the ESP8266 controller and is used by many. For this smaller model, there is a simple 3d printable case created. You can download the STL file from github. You can also order this 3d printed case as an option.

HeishaMon opentherm support

The HeishaMon PCB has also opentherm (slave) support which allows the HeishaMon software to communicate to a opentherm thermostat. In the current software release this will allow you to control basic functions of your heatpump using the thermostat or display some basic values on the thermostat depending on the thermostat capability. If you are reading this but you already have the previous non-opentherm HeishaMon PCB, you can upgrade it to opentherm using this HAT.

Connecting to heatpump

You need a cable to connect the HeishaMon to the heatpump for power and communication. If you replace your CZ-TAW1 with HeishaMon you can use the original CZ-TAW1 cable. If you don't have the CZ-TAW1 with original cable or want to connect the CZ-TAW1 (proxy) using the original cable to the large HeishaMon board then you need to get a cable from the shop to connect HeishaMon to the heatpump. There are two types of cables:

CN-CNMODE which is a 4 wire cable providing data and power and connects to the 4-pin CN-NMODE port on the heatpump. It provides read and write commands from HeishaMon. You must use this cable with the small version heishamon if you want to install the heishamon together with the original internet module (CZ-TAW1) and then run heishamon in listen only mode. But this cable works fine with the large module also.
CN-CNT which is a 5 wire cable which matches the original CZ-TAW1 cable and connects to the CN-CNT port on the heatpump. There is no added value in using this cable currently. The CN-NMODE cable and the CN-CNT cable both provides the same functions and data from the heatpump. However, as the 5th pin in this cable provides 12V power it might be used in a future update of the heishamon board where this 12V is used for providing more power.

In summary:

The CN-CNMODE (4-wire) is suitable for most heishamon setups, which also allows the small heishamon to run alongside the CZ-TAW1 in listen-only mode
Use CN-CNT (5-wire) if you need to connect the original CZ-TAW1 module to the large heishamon proxy port if you can't use the original supplied CZ-TAW1 cable or if you want to be prepared for future heishamon hardware updates which require the 12V power provided by the extra wire.

If you ordered HeishaMon before and forgot to order a cable, you can order a seperate cable using this shop item.

Powering large heishamon

The large heishamon board can also be powered directly from the heatpump. However if you are planning to use the extra features of this board like ethernet, CZ-TAW1 proxy or the relays, it is best to power the board using an external 5v usb-c power supply as the heatpump can not provide enough current for this to be active all together.

CZ-TAW1 and HeishaMon together

On the large model you can connect the CZ-TAW1 directly to the heishamon board proxy port. It forwards the requests from the CZ-TAW1 to the heatpump and back. This allows you to use the heishamon software and the CZ-TAW1 together. However for the smaller model, if you want to keep using your CZ-TAW1 for main monitoring and controlling you can only connect HeishaMon in 'Listen/Monitor only' mode so it doesn't interfere with the CZ-TAW1 communication. You need the CN-CNMODE cable from the shop for that to work. The CZ-TAW1 still connects with the original cable to the CN-CNT port. HeishaMon will then connect with the cable from the shop to the CN-NMODE connector.

Optional PCB CZ-NS4P installed

If you have the CZ-NS4P optional PCB installed in your heatpump you might have seen that the CZ-TAW1 internet module now also connects to this PCB and not the mainboard anymore. This is because the mainboard connection is now used by that optional PCB to communicatie to the heatpump. Please install heishamon also to the optional PCB in this case (on the cable where you remove the CZ-TAW1 or with a new cable from the shop to the CN-NMODE port also on the optional PCB).

Cable length

Different lengths are available which allow you to place the heishamon where you like. The heishamon board needs a wifi connection, if you aren't using ethernet like on the large board, so make sure to buy a cable long enough to reach decent wifi connection or extend your wifi with a wifi access point near to heishamon. If you need a longer cable their are multiple solutions:

Create own cable

On the HeishaMon github page you can find the connection types if you want to create a cable yourself. You can also cut a pre-made cable and insert a longer cable in between (with proper connection, like soldering). Make sure you use at least AWG24 (the thicker the better) cable and add some ferrite beads to your custom cable for any high (more than 5m) length cable. With these (and the pre-made) cables heishamon takes 5v power from the heatpump itself.

Longer cable

However longer distance cables can prevent HeishaMon to receive enough power due to resistance in the cable. If you notice data receive errors or HeishaMon isn't powering up, remove the 5v connection from the cable (only tx/rx and gnd connected) and power the HeishaMon with an external 5v power source using the marked connections for 5v/gnd on the pcb (for example the external connectors on the bottom or the dallas input side). Cables up to 25 meters are tested to work in this configuration.

TTL-to-RS485 option

If you need even more distance you can insert TTL-to-RS485 modules (XY-017 module is tested) in between and use only 2-twisted pair cables for the long distance. For the wiring see attached picture. In this configuration the HeishaMon needs a external 5v usb power also.

Further information

Recent firmwares will be publish on the github page. If you ever need to recover due to a bad upgrade, you can use any ESP-flasher to reprogram the board. For the large heishamon a normal USB-c cable is used and for the small heishamon a normal TTL cable to connect using the 2x5pin header to the 5v,tx,rx and gnd. Then switch to firmware upload mode by pressing and keep holding the 'flash' button while pressing the 'reset' button. Then release the 'flash' button. From then (until next reset) the board is in flash recover mode. Use the programmer to reflash the board with a working firmware.

Disclaimer

I will not take any responsability for any damage to your heatpump. If handled incorrectly while installating Heishamon you can damage the heatpump, just like installing any other accessoiry on the heatpump control PCB. And HeishaMon is not a replacement for the original CZ-TAW1 internet module provided by Panasonic. Heishamon itself does not provide access to your heatpump from your phone over the internet as the CZ-TAW1 does and it does not provide control or historical monitoring from the Heishamon itself. It will only provide a gateway for other software to reach this goal. The CZ-TAW1 is an excellent module for anyone who wants to control the heatpump using the app and portal provided bij Panasonic.

heishamon large allows panasonic cloud alongside heishamon

Great great piece of hardware. Had a heishamon small since end of 2022. Since beginning of 2025 a heishamon large. It's perfect that I can now also add my panasonic cloud module so my installer can support in case of errors while I can read and modify heat pump data and settings via heishamon.

Heishamon SG ready does not work

Have two WH-MDC07H3E5/WH-MDC07J3E5. Each with an Hishamon. With 3.8 both Heishamon work stable on a FRITZ-Box. To register the Heat Pumps they need the EVU-Einrichtung. In SG ready it is described that Bit1 is forseen for that purpous. Without Hishamon it works propper, with working Hishamon it doesn't. Is there any setting nessesary in Hishamon or is it still an unknown problem?

Response from TheHogNL | Jan. 6, 2025

For SG-ready you need to have installed the optional PCB and then connect the SG-ready input to that. I assume you have that?
Heishamon does not change this however if you have installed heishamon wrong, it could interfere with it. Make sure you connect Heishamon to the optional PCB and not to the main PCB in the heatpump if you have the optional PCB installed. And disable 'optional PCB emulation' if you have the optional PCB installed. Emulation is only needed if you DON'T have the optional PCB installed. You then could use SG-ready with heishamon with MQTT commands. But it seems that you already have the real optional PCB with physical SG-ready inputs

Hello, unfortunately I have had problems with the connection for 1 week.
After about 10 hours, heishamon is no longer accessible and no longer returns data to Home Assistant. After a restart, the connection will then run again for a few hours. Whether over Wi-Fi, lan, with external power supply or without.
What about?
Love Greetings
Martin Steinmann

Hallo, leider habe ich seit 1 Woche immer wieder Probleme mit der Verbindung.
Nach ca 10 Stunden ist heishamon nicht mehr erreichbar und liefert auch keine Daten mehr an Home Assistant. Nach einem Neustart läuft die Verbindung dann wieder einige Stunden. Ob über Wlan, lan, mit externer Spannungsversorgung oder ohne.
Woran kann das liegen?
Liebe grüße

Integrated WH-UX09HE8 / WH-ADC0916H9E8 with Loxone

I successfully integrated the heat pump mentioned in the subject with the help of Heishamon into Loxone.
So far I was able to read all the values out of the Heat Pump and display in Loxone. Currently I'm just reading the values and using it in my home heating automation system.
Large version PCB perfectly fits into UM100S (100*100 mm) DIN rail PCB holder.
Great product, highly recommended.

Jaroslav | Oct. 15, 2024

Review after year of use: really great product. Stable

Use small board for a year already 24/7. Stable. Works well. Hardware part is very solid! Great communication by author/seller: all questions answered. Software is maintained also very well.
The only one sequrity feature request (for software part, so not direct to this hardware) would be nice: enable open configuration wifi hotspot only when some button is pressed on the board (or double-pressed, etc.); so, only when I'm physically next to my board (not any time when signal lost with my router as for now).
In general: HIGHLY recommend! Will try bigger version with eth port also.
Big thanks for great work!

Compatibility with aquarea model M

Is the large model compatible with the new aquarea M series. I just installed the WH-WXG09ME8 pump with CTAW-1C and smart Cloud which is a bit rudimentary. So I installed the heishamon card with an ethernet module and operated it via home assistant. After some trial and error (I had to power the card via usb) it almost works except for some absurd returns like a completely wacky but repetitive COP and some other measurements that do not correspond at all to expectations or are missing. On the other hand, the statistics of the panasonic cloud are no longer powered even if all the other features via my smartphone work normally. So I guess I have to wait for an update to the M series. Thank you for your great work.
Hello, I am taking the time to analyze the return message from the aquarea M in more detail with the help of my son who is more competent than me. I will come back to the topic as soon as I have more precise information. See you soon.

Response from TheHogNL | Oct. 14, 2024

I was not aware of a new M-series yet. Please create an issue here: https://github.com/Egyras/HeishaMon/issues so we can discuss this.

Alexis | Oct. 10, 2024

Awesome

It's perfect, I had a bit of a hard time to make it talk to Home Assistant. But once i figured out the MQTT Broker and such, it just worked very easily.
Crazy good.

Heishamon v5 large - a modders dream

I was already a proud owner of the smaller v4 Heishamon (HM) version which I used to optimally control my Panasonic 12Kw heatpump (HP). While it did all I wanted, the only thing I really disliked was that it needed to connect through wifi. Due to the physical location of the HP I eventually ended up hanging a router inside the machine that communicated with the HM hanging directly next to it. When I saw there existed a version with Ethernet, it was an instabuy.

Now having the HM v5 large, I think it is even much better due to being larger. The contacts are much easier to reach and it fits perfectly in an ABB box (I could not find an the type mentioned in the description but bought `ABB M008460000` on Amazon which was a perfect fit). Unfortunately, I had the bummer of a defective W5500 unit, the third-party Ethernet shield addon. I replaced it with another and it was plug & play, i.e. I immediately had connection with my network. The HM looks very high quality and I am sure I will be a happy user the coming years.

Highly recommend!

Bartosz | Aug. 30, 2024

Great device especially large PCB.

So far I've been using a small version.
When the large version with Ethernet overlay appeared, I bought it.
The solution is awesome.
Now I can additionally leave the original CZ-TAW1 in proxy mode.
Additional two relays is also a very cool option.
Together with the home assistant it creates a perfect solution.

Marcin | Aug. 26, 2024

Overall - great device!

Very good quality and easy setup. Does the thing and does it well!
What might be bit better is the documentation - clean guide with all the modes possible and steps needed would be great for everyday user. But hey - it's a hell of a hardware for the price!
It's should be bundled by default with every Aquarea heat pump!

Ludovic | Aug. 24, 2024

Large PCB is great

Hello,

Having the small version, i just installed the large, it's great to be abble to keep the Panasonic Cloud equipement and be abble also to manage the Heat Pump with Heishamon...

Many Thanks for this great improvement !

doubt about how to make the cztaw and large heishamon connec

I have a heishamon small that works very well and I use it in listen only mode. Now I would like to order the large heishamon, but I have a question: How is the physical connection made between the cztaw and the large heishamon?

Response from TheHogNL | Aug. 13, 2024

You connect the cztaw to the heishamon proxy port (the smaller white connector) with the original cztaw cable. If you don't have that anymore you can buy it in the shop (called a CN-CNT cable).
Heishamon to the heatpump connect the same way as the small heishamon. You can use again another CN-CNT cable or use the CN-NMODE cable which is also in the shop.

So, heishamon large will be installed in between of the cztaw and the heatpump

Rouven | June 14, 2024

Question about external power supply for the large Heishamon

Hello, i got the large heishamon today and want to use it in proxy mode with the cz-taw1 on my leisha.
At the moment it runs on the internal power supply with data errors, which is probably due to the lack of an external power supply.
If I want to use the large heishamon with an external usb-c power supply, do I also have to remove the 5v cable to the heatpump?

thanks in advance

Response from TheHogNL | June 14, 2024

No you can leave it connected. There is a diode protecting it.
However I got noticed that it might factory reset the heishamon board in that situation when the usb power is removed (and still 5v powered from heatpump). I need to check on this but if you keep the usb powered, it will be ok.

Ton | April 1, 2024

Over a year of flawless communication

My HeishaMon communication PCB is working for over a year now and I never had any problem with it. It dispatches all relevant information of the Panasonic heat pump to my Homeassistant instance via MQTT.

If an Ethernet version would become available, I would buy it without hesitation.

Response from TheHogNL | April 1, 2024

Working on a complete new design currently with faster chip (ESP32-S3) and support for the W5500 ethernet shield which you can plug it on yourself. Hopefully ready within two or three months.

Mikk | March 21, 2024

Great product!

Thank you for making this! I use it to save 20-30% on heating portion of the electrical bill by heating only on the cheapest hours.
Although I'm lately been thinking about overall cybersecurity more, so two questions:
1. If my AP is for whatever reason down, anybody seems to be able to connect to the heishamon's SSID becuse it switches automatically to hotspot mode. Can this risk be somehow mitigated?
2. Will there ever be a version with Ethernet port?

Response from TheHogNL | March 21, 2024

1. There is no solution currenty but I could add a setting to set the wifi password for the hotspot. I'll think about this
2. Yes, I am working a that right now. Would probably be a version on which you can plug a ethernet module on.

Ron | Feb. 9, 2024

Excellent work, thank you! Fast shipping and fair price!

Thank you very much! Excellent work, thank you! Fast shipping and fair price! Installation worked fast and good.

Roland | Jan. 11, 2024

Very good product

I'm using the Heishamon for over a year now and I'm still very happy with it. Not a single time the Heishamon failed in the past year. Very good product and more then worth every penny!

M | Nov. 27, 2023

simply works, always. For a great price

Using this module for 3 months with my HP. As many others state in their review: it always works, it is easy to install and it gives you the control you want over your HP. This seller has every right to increase the price of this piece of hardware.

Andrea | Nov. 13, 2023

perfect interface for a good price.

I've used this interface for over six months. Always worked flawlessly, no issues, disconnections or such like the original Panasonic cloud dongle had.

The kit is very easy to setup, I've printed the box myself and stuck it near the heatpump. I've integrated everything in Home Assistant, archieving a far better control of my aquarea compared to what I could do with the stock cloud. Also, this system does emulate the expansion PCB allowing direct integration of solar systems or further configurations at a very cheap price.

Considering what it takes to properly design a PCB, go through the iterations to make it functional, I think the price the author asks for this module is definitely minute. Thanks for the great work.

Elias | Sept. 22, 2023

Work great for local controller in Home Assistant

Bought this to get rid of the awful panasonic app for my panasonic T-CAP 12 kW air to water heat pump.
The seller was helpfull and provided documentation for integration against Home Assistant.
Installation was plug and play. Setting up in HA was easily done with the provided documentation.

Is it great to have local control and get rid of the awful panasonic app and also have A LOT more information about my heat pump

Christoph | June 13, 2023

Excellent!

Excellent work, thank you! Fast shipping and fair price!

Is there a difference between CN-CNT and CN-NMODE, if I don't have a CZ-TAW1?

Response from TheHogNL | June 13, 2023

No difference. Both connectors on the mainboard of the heatpump are hard wired together (only extra 12v supply missing from the CN-CNT which isn't used).

Beny | April 20, 2023

Amazing product to digitalize your Aquarea

Amazing product amazing communication, with nearly 0 background in home automation was able to connect the heishamon to the unit and was instantly able to get the data. Home assistant part was a little bit more challenging you need to set up MQTT and connect it to it but I was able to finish everything in 30 minutes and now able to see all my data and do inputs from my home assistant, let's hope that it's stable and continues to work like this.

Tamás | Feb. 23, 2023

I was looking for this and finally found!!!

I wanted to integrate my Panasonic heat-pump with Fibaro Home Center3 and was looking for an easy solution. Well, this PCB is the perfect solution for that job. It was shipped relatively fast and based on detailed instructions on Tindie and GitHub I could connect in few minutes and set it up right away. It just simple works. Great product, exactly what I was looking for!!!

Piotr | Feb. 2, 2023

Great product

I'm using this board for some time, its 100% stable and works perfectly as expected.
Documentation is well written and complete. Shipping to Poland was quite fast.

Patric | Feb. 2, 2023

Great product

I installed it yesterday together with my heatpump and it worked instantly and flawlessly.
Installation of a mqtt broker and homeassistant on my raspi was far more difficult.
But now everything works together and I am able to check and configure my panasonic with my mobile phone.

Ulrich | Jan. 12, 2023

Works Like a Charm!

First I thought, this would be a nice addition to the "official" device offered by Panasonic ONLY for the Panasonic owned cloud, which eventually will disapper in 10 years, though....
BUT it is a complete nicely made now for almost two month working alternative, if you love mqtt and try to avoid cloud solutions when they don't make sense at all!

Thanks a lot for your work!

Cheers

P.S.: The case could be printed a bit nicer without warping, but ... who really cares? :-)

Response from TheHogNL | Jan. 12, 2023

The warping is a feature ;-) But thanks for your feedback!

Jordi | Dec. 13, 2022

Outstanding work Heishamon team!

On september 28 I bought Heishamon PCB.
Just wanted to "emulate" optional PCB on my Aquarea J to support a buffer tank.
Now the HP works like a charm. When buffer tank temp reached... it stops.
Last year the internal pump was always running to "test" water temp... with Heishamon and the availability to "emulate" optional PCB this is needed no more.
I'm so satisfied with this product, that I'm buying right now a backup PCB.

Martin | Sept. 10, 2022

A must have for Panasonic home automation integration!

I am using Heishamon opentherm with a series h T-CAP Ultra Quite. I have connected it to the CZ-NS4P add on board using the CN-NMODE plug, in parallel to the Panasonic cloud module CZ-TAW1. It worked right away. I use the MQTT data to monitor the heat pump in openhab 2.5.

Jörg | Aug. 30, 2022

Super Arbeit, funktioniert bestens...

Ein klasse Teil, ich betreibe es parallel zum originalen Internetmodul um die Daten der Wärmepumpe mit iobroker zu loggen.
Alles funktionierte sofort nach Einbau und ohne Probleme.

Vor dem Kauf war ich noch unsicher, was den parallelen Anschluss zum TAW1 betrifft, aber dank des netten Mail Kontaktes mit Igor konnte alles geklärt werden.
Vielen Dank dafür, auch für den schnellen Versand!
Gruß Jörg

Rolf | Aug. 2, 2022

Over and over again

Bought it a long time ago, but the Jeisha has only just been delivered. Crazy times!
The Jeisha is installed, test run successfully completed and of course: Heishamon also ran right away.

Many thanks for the great work and greetings from France.

Petar | June 30, 2022

Perfect product. Very good job.

Perfect product. Very good job. Very easy setup. Detailed information from the pump. Works well with Domoticz.

Mat | April 1, 2022

Even more amazing than I thought it would be!

I had quite a hard time figuring out wether my heatpump would be compatible with heishamon. But once I figured out that HeishaMon was supposed to replace the CZ-TAW1 Module, I was able to figure out that I needed the CN-CNT connector. But this is where the issues stopped. Four days after my order it arrived well packaged on my doorstep. Physical installation took 10 minutes and the software setup was a breeze. I was pleased to find a template for Home Assistant integration which had me up and running in no time.
This is what open source hard/software should be!

Jakob | Jan. 4, 2022

Great product

Works perfect, just like description.
I use it on panasonic j gen 7kw split system and pass the data to home assistant.
I use it in read only mode in parallel with the CZ-TAW1

Tim | Nov. 4, 2021

Does the job perfectly

Device connected as plug-in replacement for CZ-TAW1. Came straight up with web interface for commissioning, connected to local wireless and reported parameters on its web page. Hadn't used MQTT before, so took a while to work out how to pass data to Home Assistant, but now working solidly. Just what I needed.

Dirk | Oct. 24, 2021

Geniales Projekt / ingenieus apparaat

Die Hardware ist klasse - einfach eingesteckt und über den internen Hotspot konfiguriert, sofort danach werden alle Parameter der Wärmepumpe per MQTT übermittelt und können weiterverarbeitet werden, z.B. über InfluxDB/Grafana oder NodeRed. Einfache Einstellungen via HTTP-API oder MQTT sind out-of-the-box möglich. Schnelle Lieferung und sehr freundlicher Kontakt - sorry Igor, dass ich noch nicht zurückgeschrieben habe, Rückmeldung kommt in Kürze.

Great product. Extremely simple to setup and works perfectly

I order the PCB to control my heat pump. The setup process is extremely simple even if you have no electronics experience. It took me less than 5 minutes to get it to work and I can now control my heat pump via mqtt, which is fast and flexible unlike the default cloud service provided by the heat pump.

TOP Platine und Software

Hallo, rund rum ein gelungenes Produkt. Bei Problemen mit dem Verbindungskabel wurde mir sofort unbürokratisch geholfen. Das Ersatzkabel kam innerhalb 3 Tagen bei mir an.
Vielen Dank für alles,

Awesome product. Very fast shipping. Worked out-of-the-box.

My order was shipped the same day. I attached the PCB with the supplied cable to my heat-pump and connected the HeishaMon to my Wi-Fi network. Everything went very smooth. There is good documentation on the HeishaMon Github project pages. Would definitely buy again.

Surprised how good it is

The board is easy to setup also for limited experience user. I was surprised by all the good that is included in the SW too.

very help-ful developer

The heishamon developer and pcb seller is an exceptional kind and help-full person. both software and hardware are developed very nicely and now features are still added. thanks a lot!

Great product

Works great, but first a little difficult for me to install but that is more because i do not know a lot off mqtt and routing at all.

Thomas | Jan. 1, 2021

Great product!

Beautifully simple product, setup and working within a few minutes. It really is a no-brainer in you need mqtt from your heatpump.

Great product

Best solution for controlling a H or J series heat pump built by Panasonic.
No matter what you choose, Domoticz, Home Assistant or anny other platform of your choice.

Very good support from Igor. I had some problems during the first usage, but he was helping constantly. Eventually changing the heishamon for free!! Many stores/web shops can learn from Igor. Hopefully my coffee tasted well 😉

Works out of box

Professional built quality for low price, quick response. Works out of box, just connect and configure wifi.

The remote connectivity module you need for your Aquarea H/J

I bought the manufacturer's WiFi adapter CZ-TAW1 thinking that I can get a lot of information from the system and can remote control it fluently. Unfortunately that was not the case. I have a HomeAssistant based system for monitoring my home and use Grafana together with MQTT as well. HeishaMon does everything that I want. This PCB was a super easy way for me to start using HeishaMon: Just unplug the CZ-TAW1 and plug in the same cable to this PCB. Simple configuration and all was working. Thanks a lot!
