Week program / Schedule / Switching time on eQ-3 Radiator CC-RT-BLE-EQ

Hi :wave:,
I have installed 3 equiva Bluetooth smart Radiator Thermostats and integrated them with eq3btsmart and it works very nicely!

I am missing one function: the device has the option to set switching time periods or a week program. For me it would be nice to be able to read and set this from home assistant.

I know that I could do the automation via HA by putting the device in manual mode, yet in this case if home assistant is down it would not execute the switching.

I am happy about any help, would be also interested to integrate it myself if someone can help me getting started.

Thanks to everyone who has put work into this integration!
