better_thermostat Feature Request: Support Homematic

I'm using a number of Homematic "classic" TRV, which show up as climate. Entities in HomeAssiatant via the RaspberryMatic Add-On and Homematic(IP)_local integration

Type is HM-CC-RT-DN

Any chance that they will work with better_thermostat?

no valve drive necessary, the device does that itself automatically once a week

first wild guess for a config

HM-CC-RT-DN.yaml

calibration_type: 1 calibration_round: true has_system_mode: True

is this correct?

additionally you can group TRVs in RaspberryMatic (e.g. those in one room). They then act like one TRV (even when physically changing the setting on one of the TRVs by hand, the other(s) will follow immediately.

These groups show up in HomeAssistant as separete climate devices with the model HM-CC-VG-1

So they should work as well with a HM-CC-VG-1.yaml, but for some reason better_thermostat does not find that model

Would also love to have homematicip thermostats supported. Currently I'm using a bunch of complicated automations to make everything happen so this add-on would be a welcome addition. I'm happy to provide input and debug from my system connected to homematic if needed.
