Generic Thermostat target temperature changes constantl

Hi All!

As I’m in need for a custom heating system in my house I switched over from Homebridge to Home Assistant Core because of it’s wider possibilities.

I was able to make 3 different thermostats using generic_thermostat. Those receive their current temperature from my BLE hygrothermographs.
Every thermostat is linked to a dummy switch which are put in an automation to trigger my main thermostat to heat or not (this will later be replaced by a relais that controls my heater).

Now the problem is the following:

When I first configured the thermostats in the configuration.yaml I used target_temperature: 17.
When I started using it I noticed that the target temperature was bouncing back and forth between the set temp and the target temp.

Logically, I removed the target_temp out of configuration.yaml as I saw that it’s not really needed bij HA since some version…
However the issue remains.

The strange thing is that it only shows in the graph and that it doesn’t constantly trigger the dummy switch.

Does anyone have an idea why this happens and how I’d be able to solve this?

configuration.yaml

#Thermostaat per ruimte
climate:
  - platform: generic_thermostat
    name: Kinderkamer
    heater: input_boolean.vraag_kinderkamer
    target_sensor: sensor.kinderkamer_temperature
    min_temp: 15
    max_temp: 23
    cold_tolerance: 0.3
    hot_tolerance: 0
    min_cycle_duration:
      seconds: 5
    keep_alive:
      minutes: 3
    initial_hvac_mode: "heat"
    precision: 0.1

Did you solve this? I have the same issue with both off mine Qunbino flush on off thermostat.
When I change the target_temp_low it bounces back again.
