Just a thought. I was reading along with this troubleshooting. If the device does support more commands than the current DP set suggests, then there might be another thing to try. Maybe the instruction mode of the device needs to be changed in the Tuya IoT Portal:
It does require the creation of a (free) account on Tuya’s IoT Portal though and the intial setup of a project over there in order to be able to access the Tuya device.
I only have two Tuya devices, but non of them expose all commands via their default Standard Instruction set. I need to switch them to the DP Instruction set in order to become available.
