Bosch Thermostat 2 missing entities in ZHA

Hello all,
I have a Bosch Smart Thermostat 2 (BTH-RA) and successfully connected it using ZHA and the install code.
Compared to the information on the Zigbee Device List ( I am missing quite a few entities (% opening, boost, external temperature, …) and I don’t know why.

I have tried re-configuring it, re-paring and I’m out of ideas.

Has anyone any suggestions on how to get those missing entities?

Any help is much appreciated.
