Roomthermostat II – access floor temperature sensor

[edmundj85]

Hi,
I use the Bosch Room Thermostate 2 230V and have connected external Sensor.
I would like to access the value to use it in Home Assistent but it is only shown on the device itself and not in Bosch Smart Home, there i can only define that he use that value for heating.
Is there a way to access it?
