- reads beacons sent out by devices to find out about current state, thus no polling
- active connection is only made to change settings
- MQQT bridge automatically retries BTLE connections
- indicates connection failures/no beacons using icon
- sets correct time/date and desired PIN if not already set
Working features:
- set desired temp
- show measured temp
- read battery level (show using icon)
- set mode (auto, manual, manual_locked, auto_locked)
Also possible, but not implemented, partially because no HA support:
- set timer plan
- detect "window open" state
- set warm/cold temperature
