Folks- electrical safety is nothing to fiddle with. I would not trust Alexa, Google, or any other wifi device to control power to ANYTHING!
TURN IT OFF! WITH A PHYSICAL SWITCH! IT'S NOT THAT HARD.....REALLY!
As a licensed master electrician for 30+ years, I know the hazards of overloaded circuits.
Example- a 5 amp load will NEVER trip even a 15 amp circuit. However, the same 5 amps can start an electrical fire under the right circumstances.
I agree that the cheap Chinese power strips should be avoided. Look for the UL listing on all electrical devices when purchasing.
I've troubleshot many open neutrals/ grounds over my years in the business. Don't count on the electric utility to be aware of these and prevent them in the first place. I once found an open service neutral sending 2 amps onto the ground from the local Cable TV provider.
I can go on and on......
Again- KISS- turn the layout OFF!
