wintry flax
I recently replaced my heating programmers with a Shelly Pro 4PM, and configured a Versatile Thermostat to get temperature readings from an H&T sensor, and then use that to switch on and off the pump and valve for the underfloor heating.
Unfortunately even though the sensor temp is about 1 degree below the threshold, it keeps switching the system on and off every couple minutes or so.
What should I be looking into to fix that?
