Thermostat won't stop heating

Hello,

just installed today and trying to get it to work, but it won't stop heating when temperature is reached.

HA supervised 2022.2.0, HACS 1.21.0, Dual thermostat cb0d234

code:

# Thermostaten
climate:
  - platform: dualmode_generic
    name: Rotkast
    unique_id: climate.rotkast
    heater: switch.sonoff_1001041627
    cooler: switch.sonoff_100103c57c
    target_sensor: sensor.aeotec_humitemp_rotkast_air_temperature
    enable_heat_cool: True
    min_temp: 8
    max_temp: 42
    cold_tolerance: 0.1
    hot_tolerance: 0.1
    min_cycle_duration:
      minutes: 2

And here I'm looking at now:

Temperature is set to 29,9 - 30.1 , tolerances are both 0.1 but it still won't stop heating.

I have waited for it to stop foe 30 minutes. Then I set the thermostat to off and on again and it immediately started cooling. And yes, it kept cooling way below the set temperature. Until I shut it off and on. It started heating. Very strange...

Something wrong on my side?

Thanks in advance for you help ;-)
