ZHA: unexpected TS0012 device behaviour

chrism0dwk commented 1 year ago

The problem

This problem is related to Zigbee2mqtt moes switch problem

I have a 2-gang Samotech Zigbee Wall Light switch hooked up to my SkyConnect and running through ZHA. The physical switches work independently as expected. However, if I try to switch one gang from the HA Dashboard, then both gangs switch together. Surely I should be able to operate the switches independently from the remote source?

What version of Home Assistant Core has the issue?

core-2023.4.6

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant Core

Example YAML snippet

No response

Anything in the logs that might be useful for us?

No response

Additional information

I'm assuming this may be a bug way lower down in the zigpy stack somewhere. I'm happy to run any test Python code that may be useful, bearing in mind my HA is running as a snap.

Hi, This device is likely a tuya device, and requires the "magic spell" / "enchanted device" signature in zigpy / zha device handlers / quirks.

Any workaround for this?. I recently bough this device and the problem still there, and I am not able to make work the zigbee2mqtt...

@kryanth I wasn't quite sure if your comment was a steer towards a bit of code that needs editing, or whether it's a prompt to update some config file(s) somewhere. Care to elaborate a little?

Hi,

It's common for these devices to require a "tuya magic spell". I've done it for a few of my tuya based switches. They have the same "feature" - flipping a switch in HA toggles both "actual" switches. I find the 4 gang switches are much more consistent. Basically every time someone releases another batch of these switches, the firmware has some subtle changes and they require some magic packet interaction to "unlock" the full functions. Generally you can do it once per switch and it will be fine forever (in my experience)

I think you can run it from HA now, more info here: (might need the zha toolkit).

Hope that helps! If you follow the grapevine far enough, you can find where to add your device signature and it will be included in zha-quirks.
