ESP32-C6, zigbee, and multiple sensors

[cguhring67]

Hi,
I wish to create a stove controller, like the project here : https://github.com/philibertc/micronova_controller/tree/master
But I need porting it to zigbee, because my wifi networkis not always on.

I have managed to make working an Temp+humidity sensor in ZCZR (Router mode), after a bit of trial and error, first with esp-idf in vscode, then in ArduinoIDE, where there is more examples and the global makeup is simplier ! The connexion to ZHA in Home Assistant works fine, and i have managed to have the readings to come periodically with the oter ressources found here.

BUT ! Is there a way to name the temp sensor ? The stove has 2 different temperatures to report (ambient temperature and fumes temparature), and some other values (current state : 0 - OFF, 1 - Starting, 2 - Pellet loading, 3 - Ignition, 4 - Work, 5 - Brazier cleaning, 6 - Final cleaning, 7 - Standby, 8 - Pellet missing alarm, 9 - Ignition failure alarm, 10 - Alarms), flame power (0 to 5)... I would also be able to preserve the temperature reading of the DHT22 for comparating the values...

I have for now no idea on how to distinguish "ambient temp" from "fumes temp", and what zigbee endpoints to use for the states and flame power...

Hi @cguhring67, you can add multiple Temperature sensor endpoints to your device. The custom naming must be done in HomeAssistant ZHA, for that the custom quirks might help. But I am not using those so I can't help with that.

Also for the other values and flame power, it all sounds like something not "standard" for Zigbee Home Automation. You may need to create a custom clusters and also have the quirks for HA to read them properly. The custom clusters means that you will need to have your own class implementation derived from ZigbeeEP, which will have all you need. That part you will need to take care of.
If you will start on this, feel free to ask for some help here or on Discord, if you will have any troubles :)

About the quirks you can check this repo: https://github.com/zigpy/zha-device-handlers

Hi, thank you for your answer !
So, I think that i can probably tinker a bit...
I really need only 2 flames power : 1 and 5, so a "contact switch" for setting min/max power should be OK.
For the states, I could also end up with an "on/off" Switch and report, and some others binary states (0 or 1) for the others readings/errors...
What actually defined Endpoints (in the library) do you think I can use for these states reports ? The Occupancy sensor Endpoint seems to be a good candidate.

In HomeAssitant there will be in future versions supported AnalogInput, MultiState and BinaryInput which may solve all your use cases. We have the AnalogInput already supported in Zigbee library but it's not showing up in the HA. When all of those will be added to HA, I will also add support for it. For now you may need as you said tinker a bit :)

The occupancy is an IAS Zone which have a bit stricter rules to send the "data" to coordinator but it may still work for you till there are not many other options now :)

Hi,
Thank you for your reply !
The zigbee part of the project seems too much complicated, in regard of the time I have for it (near zero...) So I have decided to switch to ESPHome with a WT32-eth01. The compononent in esphome handles all I need wery well, I have installed it today, and it just works :)

But, for sure, i will use ESP's in zigbee fort temp/humidity sensors, and also for light control.
