The problem

The device has 3 functions: Light intensity sensor, temperature sensor and door open/close sensor. The first 2 work OK, the door status however remains 'unknown'.

Please attach the device diagnostic information that was requested by the issue template.

I included the file below already. It is the zwave log, I don't know how to create a logfile that is more specific to the actual device. I opened and closed the door during the creation of the file. Please let me know if I can do anything more to help solving this problem.

Also please indicate the timestamps in the log where you opened and closed the door.

Did you change the value of config parameter 7, "Customer function"? According to the manual (and Z-Wave JS DB entry), the default configuration is to send Notification Report messages when the door is opened, which is what the referenced entities are for. The way the device is currently configured, it is not using Notification Reports but Binary Sensor instead, which is seen in the logs.

In this current configuration, you need to enable entity binary_sensor.door_window_contact_sensor_state_door_window (default disabled) and use that instead of those others. Or change the setting to send Notification Report. First option is easier.
