Internal thermostat heating action is activated when is not expected #18073

Closed soyxan closed 1 year ago

soyxan commented 1 year ago

PROBLEM DESCRIPTION

I am using the Tasmota thermostat implementation (https://tasmota.github.io/docs/Thermostat/) and overall is working ok, but the following screenshots show a strange situation that is occurring very often:

As it can be seen in the first screenshot, the heating action is working as expected from 18:00 to 21:00 (the setpoint is 23ºC and the current temperature is below, so the heating action gets activated) but at around 5:30 the heating action is activated again when according to the setpoint is not needed.

In the second screenshot, it is shown a room with constant temperature setpoint for all day (19ºC) and from time to time the heating action is activated when not expected.

I'm using Thermostat day by day and it has a lot of different parameters, but I must admit that sometimes, on my side it has strange issue also such as powering for 1/2 seconds without understanding why.

Also you need to check that your device does not reboot because in this case in need back calculation on fresh start.

May be another option would be to switch to PID mod to compare.

I left all the Tasmota thermostat parameters by default (that means hybrid mode: ramp-up + PI). The thing is that as you can see in the trends I am not talking about some seconds, the thermostat actuates for more than 15 minutes (constantly)

I suggest that you log to a syslog server continuously with syslog 3 to have details It may explain why tasmota decide to heat when not needed
