Bosch BTH-RA (Radiator thermostat II): Add firmware 3.06.08 from November 20th, 2024

[DerDreschner]

Yesterday, Bosch released a new firmware for their radiator thermostat II. It has the version number 3.06.08 and includes several changes to their heating algorithm according to their changelog.

Radiator thermostat II
The heating control algorithm has been revised at some points to address specific states in the wide range of heating systems more effectively. The set desired temperature is now reached and maintained more quickly.

As they don't release an official download, I had to sniff the firmware once again. To test the package, I updated another thermostat afterwards over Z2M successfully.

Enjoy!

[mmattel]

Great, many thanks.
Hopefully this will fix the "does not always remember the original temp when switching back from windows open state"...

[DerDreschner]

@mmattel : Fingers crossed! 🤞 I use "Better Thermostat", therefore, I have no experience with the native open-window-implementation. But would be interested to know if it's fixed for you or not.

[mmattel]

Sure!
In a nutshell, I have door sensors that trigger on open/close. In HA, I use an automation that gets triggered by the sensors and progresses if the states do not change for a defined time. Then I check if heating is not off and trigger window open/close on the bth accordingly. This works process wise totally fine, but the bth somtimes sets back the temp not back to the former but much lower value...

[Koenkk]

Thanks!

@DerDreschner The update went frictionless, many thanks ! 👍
