Hi, 

I have problems with 3 of 16 Tapo S112 modules used for the rolling shutters. Installation was made by an electrician. After a few days these S112 show the error "possibly error with the wiring". Rollers can't be operated by the Tapo app nor the hardware switches. But an operation with "Smart Things" by Samsung is still possible. It shouldn't be an issue with the WiFi connection as the other modules don't show this error. Could it be a peak in the AC when the roller is operated and limits are exceeded? 

Thanks for any help.
