Is it loading the zhaquirks.tuya.ts0601_electric_heating.MoesBHT? It looks like the last input and the output clusters are not covered in this quirk.

It is the default ts0601_electric_heating quirk. It just adds the MoesBHT class when loaded. It is not loading the quirk because one of the input, and both output clusters does...

@darknessblade I've double checked and in fact all clusters on endpoint 1 are handled correctly by the current quirk. However your device also lists endpoint 242 with a single output...

Ok, there was a bug in the previous file. Try this: [ts0601_heating_avatto.txt](https://github.com/zigpy/zha-device-handlers/files/12671461/ts0601_heating_avatto.txt)

I'll make a bare minimum quirk, if that does not work we have to call on @TheJulianJES or @javicalle :-)

Try this: [ts0601_heating_minimum.txt](https://github.com/zigpy/zha-device-handlers/files/12671666/ts0601_heating_minimum.txt) If this does not work, then i believe the manufacturer specific cluster is not compatible with Moes and more info is needed.

But it loaded the minimum quirk? Then we can use that as a starting point for implementing the manufacturer specific cluster.

We could try the Haozee cluster for a test. It seems from your log that it is looking for this. Let me throw something together.

Give this a shot: [ts0601_heating_avatto.txt](https://github.com/zigpy/zha-device-handlers/files/12672066/ts0601_heating_avatto.txt)

Ok, there is one last thing we could try, let me do a little research. I might be able to find the manufacturer cluster spec.
