Comet Blue thermostats

• reads beacons sent out by devices to find out about current state, thus no polling
• active connection is only made to change settings
• MQTT 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 and target temp
• apply offset to measured temp (should be the same you set on the device) per device in config file
• 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

Example device configuration.yaml block:

climate:
  - platform: sygonix
    devices:
      'Living Room':
        mac: 'AA:BB:CC:DD:EE:FF'
        pin: 000000
        offset: -1.5
