Version 1.1.0 - Thermostats support

✅ Thermostats

• Supported when "Get thermostats" is enabled in the config flow.
• For each thermostat the integration creates two entities:
  • a climate entity (AveThermostat) representing the controller
  • a number entity showing the current temperature offset of the device (–5 °C..+5 °C)

Climate entity behaviour

• Mode controls the combination of season and on/off state:
  • Cool for summer mode
  • Heat for winter mode
  • Off if the thermostat is powered off (support depends on the device)
• Preset is either Schedule (follow the schedule on the webserver)
  or Manual (immediate changes from Home Assistant). Changing the
  target temperature from HA will automatically switch the preset to
  Manual, mimicking the vendor app behaviour.
• Fan mode reflects the fancoil speed reported by the zone; it is read‑only.

Offset sensor

• A read‑only number sensor is created for each thermostat exposing the
  device’s current offset.
• The offset cannot be modified from Home Assistant; it must be set on the
  physical thermostat itself. The sensor simply mirrors the value reported
  by the device.
