ZigBee TRV TS0601 BRT-100-TRV is missing logbook events

I have 5 TRVs TS0601 integrated using Z2M. All is working fine except that the Logbook is empty:

I cannot see when and how my automations change the desired temperature (by applying scenes) for that device. How do I fix this?

Temperature settings are not in the logbook.

Sensor entities that have been assigned units (i.e., have a unit_of_measurement attribute) are assumed to change frequently and those sensors are automatically excluded from the logbook.

The automation should have traces though.
