Works like a dream, can connect so many devices!

For Zigbee dongle - ZB3.0

Hi,

I came from a CC2530+CC2591 combination with external antenna. It worked just fine on my PI4 with Home Assistant - good range - but it had a maximum of 20 devices which was not enough, even with separate routers.

This CC2538 + CC2592 Zigbee dongle is an excellent solution that can be easily integrated into Home Assistant. It works great, is well-made , carefully packed and comes with instructions. It reaches every corner of my house with a good signal. Even in this Corona-period, it was shipped quickly and it arrived within a week!

I now use this dongle in HA with Zigbee2mqtt and it works perfectly, truly highly recommended!

The only thing I could not find yet on either the Tindie website or instructions is how to upgrade the firmware without JTAG (so using USB port). It would be nice if this information could be added to the page (or a link to the instructions). It seems to have the 'flash' button, but without instructions I would not dare to upgrade it now.

Great experience all around!

For Zigbee dongle - ZB3.0

The product was exactly what was advertised, and the zigbee dongle is working great! The communication about delivery, the short tutorial on zigbee2mqtt and overall shopping experience was very pleasant. 10/10 would buy again (if I ever need another)

Thanks Casper for the nice review !

Everything OK

For CC2530 + CC2592 - Zigbee dongle

Good product, fast communication, longer time to delivery to Czech republic but it is a problém of carrier

Response from Giovanni's Domotica Store | Jan. 16, 2021

Many Thanks Petr, yes indeed December was a very bad month for shipping items, but I'm happy to hear that finally your parcel arrived!

Excellent product!

For Zigbee dongle - ZB3.0

I got two of them and was expecting an easy transition from the cc2531 stick that I had been testing with. For me it was not straightforward, but this was due to my setup. There was an other integration still trying to access the USB serial port and caused the device to lock. I soft bricked one by attempting to 'fix' my issues by flashing a different firmware, but Giovanni set me straight. Both are now working perfectly, and I am very pleased.

There is a minor issue with one of the sticks where the flash button is broken (the metal housing of the button came loose) but I have a workaround for that if I need it.

Thank you for your help in figuring it out!

Response from Giovanni's Domotica Store | Jan. 16, 2021

Thanks JW to share your experience, glad to be able to help you to bring back both dongles to work!!!

Works Great

For CC2530 + CC2592 - Zigbee dongle

Bought 2 configured as routers, one to replace a CC2531 dongle that was barely able to get through a wall (LQI on 3 devices was between 0 and 1 with them dropping off the network at random and needing re-paired to work again) and the other to extend the range and improve stability on a network with 90 devices running on a CC2652RB coordinator on Zigbee2mqtt and Home Assistant. They have been running for almost a week now and the 3 devices that were dropping randomly have a LQI between 50 and 65, nothing has dropped off the network since re-pairing all the devices that were connected to the old CC2531.

Thanks Giovanni for the great product.

Response from Giovanni's Domotica Store | Jan. 10, 2021

Thanks a lot Alastair for the nice review! Good to hear you are able to get back a stable zigbee network with a much improved LQI levels!

No doubt the best zigbee controller you can have

For Zigbee dongle - ZB3.0

Long time z-wave user, I was skeptical of the zigbee range and reliability. Tested a couple of other Comercial options and ended up returning.
Decided to buy this device and its flawless. I have battery powered devices far away, with obstacles that other controllers couldn't reach out. This one, won't lose a single message. Have some issues with the postal service during Christmas time and covid disruptions but the seller was always available and willing to do his best to expedite. Super satisfied.

Response from Giovanni's Domotica Store | Jan. 10, 2021

Thanks Wesley, Happy to hear dongle arrived (sorry for the delay!!!) and you are satisfied with performances!

CC2538

For Zigbee dongle - ZB3.0

Ho comprato 2 chiavette 2538 e ne sono molto soddisfatto.
Io le uso in HA con Zigbee2mqtt e funzionano bene.
Ho accoppiato tutte le mie lampadine HUE eliminando l' utilizzo del bridge.
Ho messo qualche sensore di temperatura Aqara e li rileva bene su diversi piani della mia casa.
Mai una disconnessione.

Aggiungo la completa disponibilità di Giovanni ad aiutarmi su alcuni miei errori.
Consigliatissima

Super device - very good seller

For CC2530 + CC2592 - Zigbee dongle

I ordered the dongle via express, all went well.
I swiched all ma 55 devices to the new dongle in this way:
- stop zigbee2mqtt
- changed the tty entry in config-yaml
- forced to generate a new network_key in config-yaml
- deleted all the devices in config-yaml
- restart pi
So i started with an empty MQTT but had all flows.
Connected devices 10 by 10 an renamed, checked flows, all works fine.
At the first look it seems more robust than the CC2531, i will tell end of january.

Thank you Giovanni for this good work.

I'm happy, definitely a different planet than my old CC2531. With this dongle I reach every corner of the house with a more than good signal. Excellent interaction with Home Assistant. I advise.

Excellent choice

For Zigbee dongle - ZB3.0

The dongle has been now up and running for a week now - absolutely fantastic. Not a single problem.

Compared to my previous dongle (CC2531), I can pair devices (I have 56 pcs currently) directly to the dongle (although obviously some wanted to connect via a router device) and the range is much higher. I don't have LoS to any device, dongle is in a storage room, minimum 2 walls to outside, still a battery operated device (Smartthings button) works at least 30m away, at the edge of my property. That is way farther than with previous dongle, which had trouble even indoors (just a note, I have some Xiaomi sensors that don't like to be rerouted - pairing directly to dongle ensures there is no rerouting. Thus the dongle range makes a difference).

Attached documentation is limited, and links to zigbee2mqtt.io -pages anyway. Installation and pairing couldn't have been simpler. Shipping was prompt, but took 2 weeks from Italy to Finland using standard shipping.

Communications with the seller is excellent, quick responses to queries.

Thanks a lot!

Response from Giovanni's Domotica Store | Nov. 11, 2020

Thanks a lot for your nice review, really apreciated!

I am sorry about the long waiting time due to the shipping delays, I am looking for a different courier with reasonabile price to be able to offer a better shipping service.

Works out of the box

For Zigbee dongle - ZB3.0

Reasonable fats shipping, instructions for setting things up were included.

I'm using this in a home assistant context with zigbee2mqtt on a pi4.

One little question: not sure what the exact FW version is and are there possibilities to update it later on (and how)?

Response from Giovanni's Domotica Store | Nov. 8, 2020

Thanks for your review, firmware is Koenkk zStack 3 latest version.
Yes you can upgrade the firmware but you need to use a JTAG programmer as explained in my tutorial on the official website --> https://www.zigbee2mqtt.io/information/flashing_the_cc2538.html
I'm currently working on new release of this hardware that shoudl allow USB flash of new firmware using a special bootloader, but it's still under prototyping...

Zigbee dongle with very good coverage

For Zigbee dongle - ZB3.0

It has better coverage than cc2531 so it does the job. Nice 3d printed enclosure.
Firmware is already installed, so I just plugged in, repair all devices, and it flawlessly works with Home Assistant.

No documentation needed, no communication needed.

Response from Giovanni's Domotica Store | Oct. 31, 2020

Thanks George for the nice review, apreciated!

Ronald | Oct. 30, 2020

Perfect stick

For Zigbee dongle - ZB3.0

I run it now for 4 weeks.
It works direct out of the box.
The amount of devices it can handle is indeed much better than the basic CC2531.
It supports all my 35+ devices.
The data process speed is also much faster.
The only con is the range, it is not significant better than the CC2531 with antenna but with some extra smart sockets I can extend the range.
Overal I'm very glad I bought this stick.

Response from Giovanni's Domotica Store | Oct. 31, 2020

Hi Ronald, thanks for your review, all in all positive, I'm sorry your coverage improved by small amount, I can assure you I use a chip with -20db power amplifier and each dongle is tested, I can only assume you have some big "ostacles" (like walls or concrete pavement) that can have serious impact on the signal strenght.

thanks!
