Zigbee depth sensor with ESP32C6

[GaetanNaulin]

Hello !
I'm new in the esp32 community and in Home Assistant comunity too. I try to develop a water well depth sensor with an ESP32C6 and a QDY30A. I'm able to get the data from the QDY30A without problem, but for sending it to zigbee2mqtt, I'm lost. I can send it through ZigbeeTemperature, ZigbeePressure... But never it is a value in meters. I think I'm missing something but I don't know what.
What's the best way to send a value in meters through Zigbee with Arduino IDE and an ESP32 ?
Thanks !

Hi @GaetanNaulin, there is no standard cluster that can be used for length/depth values. But I guess you can tinker a bit using any of the sensors you mentioned, but the in HomeAssistant you can redefine what the value means. So you can have meters instead of °C for example.

I'm doing the same. ))

I have already implemented data transfer to the Home Assistant (HA) via z2m. All you need to do is write a converter for z2m, it's not difficult. But I've moved a little further, and now I want to control the pumps' activation depending on the water level. Ideally, this control will be configured via HA, but the transfer of socket control commands will occur directly between the devices without the participation of a coordinator and HA.

You can start with this example. If you have any questions, let me know.

const m = require('zigbee-herdsman-converters/lib/modernExtend');


const intReporting = {min: 0, max: 60, change: 100};
const doubleReporting = {min: 60, max: 60, change: 0.1};
const settingsReporting = {min: 60, max: 3600, change: 0.1};

Many thanks for your answers !
I didn't understand that a converter in z2m could make the job ! Thanks for the example, I'll going further with this.
