I assume the firmware of the device isn't pretty fault tolerant and/or stable. If you send to many instructions / request to many properties at once / a measurement cannot be done in time the device response with "invalid operation". Another idea: If you call invalid methods (f.e. buzzer on/off) the device response with "invalid operation". Please enable to debug log and try to provide the traffic (requests & responses).

same here. I didn't perform any action to the dehumidifier. The error just happen itself.
