Hello,
I am having the same problem with the Yeelight Dual Control.
The modules randomly turn on and off by themselves, even when there is no command from the app. Sometimes they also do not respond to the app at all.
The wiring has been checked, and the module is connected to proper live and neutral wires.
Because the same behavior occurs in different setups, I suspect the module may be faulty.
Could you please advise what to do next?
Thank you in advance.
Best regards,
