How to add custom nRF device to zigbee2mqtt

[Gabriel Pinto]

Hello there! I've been developing a custom device with a nRF52840 dongle. For this I had to develop a custom cluster to properly support the type of data I wanted the device to output.

The device outputs 2 temperatures and a current. I've managed to properly set it up and I got it communicating between 2 nRF52840 dongles, but now I'm looking to use a zigbee2mqtt dongle based on Texas CC2531 as a coordinator to receive the data. This is where I'm finding difficulties, as no one in the Z2M community seems to be able to help me or point to an example. I can pair the device and even got it to be recognised as "supported" by z2m, but no data is being received, this probably has to do with the fact that I can't bind the custom cluster I've created for this device with z2m.

Does anyone have any experience with this particular case that can help me?

Thank you and best regards.

Hi,

I am sorry, we are a little low on zigbee competence in tech support for a couple of weeks due to vacations. Mayne this would help:https://www.zigbee2mqtt.io/how_tos/how_to_support_new_devices.html

Hi. No problem, thank you for your assistance!

I've already tried to follow those instructions before, seems like for custom devices there are some steps that aren't detailled enough, at least for me. It probably works fine with a custom device that outputs temperature for example as defined by the ZCL standard, however my custom cluster exposes 2 temperatures and a current, so I have to define that somehow on the Z2M side as well. 

Following that link I've already managed to add support for my device, it is now recognized, vendor and model and all those things, I just can't get it to receive any data from it.

Hi,

I checked with the zigbee team, unfortunately: "We do not support zigbee2mqtt (and vice versa Nordic devices are not on supported devices list by zigbee2mqtt) therefore we are not able to help with that."

I'm aware they're not directly supported, but zigbee2mqtt is suposedly open source, and you should be able to add support for your custom device no matter what it is, you just can't use their "preset" device types, you have to create your own with proper binding to a custom cluster, this is the part I'm failing to achieve. 

Thank you for the help anyway.

Best regards

Hello,...

I was just wondering if you got anywhere with this.     I'm wanting to put together a HA solution using rPi or a linux VM.
There's a lot of super cheap ZigBee dongles on the market, it would be great to use a good quality one like the nRF52840.
