We had a bedroom that had a high pitched beep you could hear most of the time. Finally discovered it was one of our Wyze plug units with a lamp plugged in. Remove the lamp and it still beeps. Remove the plug and the noise stops. Bad WYZE plug I assume. Anyone else notice a high pitch beep? It can be difficult to hear unless the room is quiet.
The worst that can happen is it starts a fire.
If it’s less than a year old, make a warranty claim. Support will probably make you run though unnecessary troubleshooting but, just say nothing is working until they offer you a replacement.
