Tuya Zigbee Thermostat not reacting on one window

[monsterflo]

Hello All,
I posted this in the HA forum twice but apparently nobody had a solution. So I give it another try here.
I advanced in using Schedy for my heating schedules. The unsolved problem still is that the thermostats do not react when a window is opened. The used thermostats are Zigbee Tuya thermostats.
After browsing the web I found a configuration that promised being the solution but it is not:

actor_type: thermostat
actor_templates:
  default:
    off_temp: 5
    supports_hvac_modes: false

The log still states the following:

2022-03-01 20:15:10.616086 INFO schedy_heating: --> Attribute 'state' of 'binary_sensor.door_window_sensor_wc' changed from 'off' to 'on', reevaluating <Room R:wc>.
2022-03-01 20:15:17.592606 INFO schedy_heating: --> Attribute 'state' of 'binary_sensor.door_window_sensor_wc' changed from 'on' to 'off', reevaluating <Room R:wc>.

Can someone suggest anything to fix this?

Here is my schedy_heating.yaml

schedy_heating:
  module: hass_apps_loader
  class: SchedyApp

  actor_type: thermostat
  actor_templates:
    default:
      off_temp: 5
      supports_hvac_modes: false

  expression_environment: |
    def heating_mode():
        return state("input_select.heating_mode")
