Does exactly what I did. I have warned Sonoff several times that they have a fault in the thermostat.
The created thermostats turn each other off and on. On one thermostat the target temperature is reached and on the other not. The thermostat turns on the heating and the other turns it off and so they are in a loop.
The solution is that when the thermostat is heating, the other thermostats will not be able to turn off the heating if they use the device together.
Imagine that if you have 4 thermostats and the first thermostat starts heating, it will turn off the other thermostats until the heating is finished.
This is how the heat pump, which cost 15,000 euros, keeps turning on and off. I wonder when someone will find someone who will want compensation for the destruction of the heat pump.
