restore_from_old_state: False
restore_parameters: False
restore_integral: FalseI observed that for about hour to discover that despite 3 of my satellite rooms were below setpoint (in some cases even by 0,5 degrees), they never switched to "heating", yet my main thermostat was kicking off few times for very short time (so I am wondering what triggered it if not satellites)

8:42:59 AM - 41 minutes agoAs last attempt, I used following master thermostat configuration (without weather mode):
- platform: multizone_thermostat

sensor_filter: 3
initial_hvac_mode: "off"
initial_preset_mode: "none"

sensor_stale_duration:
hours: 12
restore_from_old_state: False
restore_parameters: False
restore_integral: FalseAnd despite few rooms being below setpoint, which did not trigger any of satellite thermostats to "heating" hvac action, I went ahead and changed setpoint on one of rooms to +3 degrees up. That instantly triggered satellite to "heating", however master thermostat did not react. I did wait about 30 minutes, and nothing changed.
I can't figure out what am I doing wrong - to get the rooms operate based on PID controller and weather mode and trigger main thermostat when satellites need heat.

Hello. I started to use the thermostat to get better control of heating source turning on/off. Before, I used adrein.b's smart thermostat with PID, which works ok, but logic to turn main heater on/off is done simply outside of that, via automation. I check every 5 minutes if any zone needs heat. That, sometimes, results in turning it off while other zone will demand heat in a minute and will turn back on shortly, which is not ideal for heat pump.
I started with the following configuration:
Which resulted in too many on/offs in short cycles:
I am not using valves with position, just on/off. Weather compensation helps a bit as it won't take that much to heat the room if warmer outside, so that definitely helps to reduce the overshoot. My main heat source (heat pump) modulates the leaving water temperature based on outside temperature already, so this is really only about not running heating that long in particular zone.
With smart thermostat, I was using following values, I am not sure if I can just use them here as well, depending on the calculations:
I suspect pwm and min_cycle_duration could help me reduce those short on/offs?
For starters, I changed restore_* = False as suggested by you in forums. I also removed room_area for each room, and part of the configuration in the master thermostat, to use only PID and weather. I am not sure where to set pwm=0 as I have only on/off valves, and like in adrien's thermostat, where to set alternative to pwm, min cycle duration,... My goal here is to get better handling of main heat source, and its' on/off cycles.
