Tindie

Does what it says on the tin! Documentation was great and the device itself was simple to set up and seems to work just as described.

I used the included double-sided tape to attach it to the lid of my softener's brine tank, took some measurements for what the full and empty levels were, and followed the manual to set it up with my WiFi SSID and MQTT credentials. Added the config from the manual to my Home Assistant instance and it started receiving salt levels without any hassle, added a few bags of new salt tonight and the level went up as expected. Looking forward to fewer instances of running out of salt going forward!

Wonderful invention to solve a niche, but important need!

Many thanks for building such a polished device!

Keep in mind you'll need to prepare a nearby power source. Most people should have an outlet available from the water softener.
To be more careful with the tiny microUSB port, so I added a magnetic USB cable for powering the salt sentry.

Works brilliantly!

Awesome little device

I ordered this because I constantly forget to fill my water softener. I wanted the measurement sent to my Home Assistant server so my Magic Mirror setup could then read it and display this data in a nice UI.

This sensor worked perfectly out of the box. Plug it in, search for it with your phone, set up some configurations such as wifi credentials, mqtt connection info, and measurements for the tank itself and it was good to go. I did have to adjust the measurements a few times after I positioned it with double sided 3M tape. I look forward to watching this measurement change as the tank slowly depletes.

I'm very glad this solution exists. Great work.

As plug-n-play as you can get it

Works wonderfully and as plug-n-play as you can get it.
Minor point:
- Wish it came with doublesided 3m tape. I didn't have any at home so it required a quick trip out to the hardware store.
- Wish the documentation includes default values for various types of water softeners. But that's easily solved with some quick measuring.

Other than that it works beautifully with my Home Assistant setup after creating the necessary sensors.

Thanks for your review!
Valid point, I should indeed include a piece of tape, will add it to any subsequent orders.
I will also see if I can include a list of water softeners and recommended empty/full levels, so if anyone has proper values for a certain water softener, please send me a message.

Awesome!!!!

After buying the Doorbell Modernizr 2 i have had a couple of small issue's.

So after contacting for support i received a quick reply with handson tips and support which helped me quickly to resolve the issue's.
And i am so happy with the result.

if you dont have specific need for a video doorbell this should be your purchase.
Now i simply get a push notification on my phone when someone is at my door.

Thanks very much for creating this awesome device.

I greatly recommend this.

Amazing Product!

When thinking about making my doorbell smarter, id didn't wanted to replace the existing with a doorbell camera.
A friend of me told me about this project and how easy it was to install. After waiting a long time I finally decided to buy the Doorbell Modernizr 2.
What a great product and super easy to install. I have hooked it up to my Homey from Athom with MQTT, works like a charm!

Great product

Next day delivery? Yes indeed.
Installation? Pice of cake. Connect power, connect wifi, configure wifi, configure MQTT and done.

I've installed the DM2 in a different way then documented. I've connected the doorbell button (and 8V power) on the left and connected the doorbell button and the ringer on the right. Now I can mute the physical ringer and the DM2 always sends out a MQTT when the button at the door is pressed.

Great product!

great product

Easy installing.
I had some problems to push the buttons because the holes in the housing did not match but that was easely solved with a small drill. (remove the electroncs before you drill)

No stable WiFi connection

No able to establish stable 2.4GHz WiFi connection with Unifi AC-pro. Known issues with used ESP chipset.

Sorry to hear you're having trouble with the Doorbell modernizr.
I actually have a Unify network myself, including a AC-pro and am not aware of any issues.

Please contact me to see if we can solve the issues, otherwise you can of course always return it.

works like a charm

Wow, impressive fast delivery (next day). The Doorbell Modernizer comes in a solid box and a nice looking booklet as user manual. It looks very nice and professional all together.
The installation goes very smooth (unless you make a silly mistake like I did). And even when you do make some mistake, there is always an email adress available for assistance. In my case I got an answer within hours. I work with Home-Assistant and for DM I had Mosquito broker installed. Without having extensive knowledge of it all (like myself), it works pretty straightforward.
Conclusion: on all domains amazing: the product looks nice and does what is promissed; the shipping couldn't be any faster, the documentatione in complete and understandable and the e-mail communication is spot on.
So if you want to modernize your doorbell and have some automation fun, Doorbel Modernizer is really the way to go!

Ideal solution - quick & easy to setup

Very please with this. It was no hassle to set-up, and is all tidied away in its happy & perfectly sized small case.

Documentation is perfect, and I was up and running in no time.

I'll probably be pestered to set some up for my friends now ;)

works great

Using it with mij home automation system with wice it works very wel sent a picture to mij telegram and let Alexa tel me there is someone at the door.

Great product, fast shipping

Great product with fast shipping.

Maybe it's good to mention that a home automation system (Home assistant, Domoticz and Openhab) is optional, as long as the device has access to a MQTT broker. I don't use a home automation system, but I have a Rasperry Pi with a MQTT broker running. I wrote my own software that listens to the MQTT topic to which the Modernizr publishes a message. Works great for simple tasks, like sending a push notifications on doorbell press.

Works great, but power connection could be better

I set up the doorbell to work with HomeKit via Node-Red, and it works perfectly. My only issue is with the power supply: the product description says it's a 3.5mm barrel connector, but it's actually 5.5mm. Aside from correcting the description, I'd suggest swapping it out for USB. The power required is 5v, and even though 5.5mm barrel connectors are common, they are rarely used with 5v power supplies - they're much more commonly some multiple of 3. So it is unlikely a user will just have one lying around (vs. about ten chargers I had with the right connector but wrong voltage). Since USB is 5v, and has become the standard connector for small devices, it would be much more convenient to just use that (but preferably USB-C for robustness and future-proofing).

Well documented, easy to setup solution

Well documented, easy to setup solution for adding extra functionality to your traditional doorbell.

Exactly as described

Works exactly as advertised.
Put it parallel to my bell, added Wifi + MQTT config via webinterface. Home Assistant sends me a push message to the phone and blinks my Hue lights.
Thanks!

Very usefull and working pcb

For Wifi to 433Mhz board with ESP8266

Nice to see a solution for HA projects from Holland and don't forget to look at the unique projects on Erik's Github..

A small detail : The ground of the RF unit is on right side..

Lex | June 13, 2018

good product

I ordered this board to automate my doorbell and I really like the quality of the board.
At first, Erik sent me the wrong board and left me a message. So I returned the board and got the right one a day later.
Fast shipping, great build quality and good communication with the seller!
