Home Assistant custom integration for Bluetooth Low Energy (BLE) control of AC Infinity Airtap series register fans.

• Simplified entities: removed auto/climate mode controls; temperature is now a read-only sensor rather than part of a climate device
• Single fan speed: replaced separate min/max speed controls with one speed setting (1–10) that the device holds across power cycles
• Stability fixes: resolved a 500 error during device discovery caused by nearby non-AC-Infinity Bluetooth devices, an assertion error on switch toggle, and a config entry serialization issue that could cause the integration to fail after a restart

To enable debug logging, add the following to your logger config:

logger:
  default: info
  logs:
    ac_infinity_ble: debug
    custom_components.ac_infinity: debug

Built on work by mtsphere and originally Jason Hunter (hunterjm). Uses the ac-infinity-ble library.
