 ## Receiving signals from BLE tracker devices for Presence detection
-The gateway can detect the BLE trackers from Tile, NUT, TAGIT, ITAG, MiBand, Amazfit and RuuviTag and create automaticaly a device tracker entity following the Home Assistant discovery convention (if the auto discovery is activated).
-To do this activate the "BT: Publish HASS presence" switch in your controller or send the followng MQTT command to your broker:

 The entity created can be attached to a person to leverage presence detection. The `away` or `not home` state is triggered if the BLE tracker is not detected during the timer defined by `presenceawaytimer`.
