Tuya TS0002_switch_module does not trigger individual channels

[andregoncalvespires]

What happened?

Hello everyone.

I already use several devices model Tuya TS0002_switch_module and they all work perfectly. Right now, I'm replacing the latest wifi devices with a few more of this model. And to my surprise, I'm encountering strange behavior. After pairing on the Z2M, when I turn on one of the channels, the other is also turned on. I imagined that it might be a need to update the firmware, but when pairing them in a tuya hub, there is no update and the operation is perfect.

This problem only happens for new devices, the ones that were already on the Z2M continue to work perfectly.

Can anyone save me?

What did you expect to happen?

That the operation of the channels were independent

An important information, the problem also happens with ZHA

The device is very likely need "tuya magic spell" being casted on it for working normal (like most tuya devices updated firmware).

I have one 4 gang version bayed for 7 month ago and its working OK (in ZHA) but very likely its having older firmware as your new one.
