Get a zigbee controller, install zigbee 2 mqtt. Set z2mqtt to channel 25 to lessen wifi interference. Buy third reality zigbee temp sensor. Use the temp sensor to control the ac plug. I use versatile thermostat from HACS to turn on off.
My wife's has never been below shoulder length so I have no experience. She's telling me she had it longer but before me, that's 25 years. Lol.
