ESPresence to track Smart Phones, Smart Watches, Tile, almost any Bluetooth devices 

yes. i will make a video for you when i can.

@@dablet I'd be curious to know that too! I couldn't find a video of it. "hi ! do u know how to make HA do an automation when the device is detected ?"

@@halasizsAs explain by dablet in video You have two parts. You have the sensor that you detecting as the bluetooth signal . And the espresence device that provides the location of the detection. So your trigger is the espresence at a specific location label say garage. And a bluetooth watch that is identifier say Joe. Homeassistant espresence devices always report the closest location match. So when Joe moves from kitchen to garage Joe is detected in garage from kitchen. That is your trigger . Or reversly when he leave the garage. Then sensor is joe's watch and the device detecting it is garage ( espresence ) . The action can be anything like garage lights OFF. One thing important is that esprence is slow to react so turning lamps OFF is the way I use it . I cant post printscreen but you can get a feel of the result with yaml as follows , here the automation is to turn garage light off . The action part is anything you can control exemple garage lights. I detect when joe is leaving from garage. Please also note that presence sensor are specific so you need to sense for anyone allowed. the trigger part is interesting part the rest of the automation is standard: platform: state entity_id: - sensor.joe from: garage for: hours: 0 minutes: 1 seconds: 0 id: JoePresenceOFF to detect joe presence in garage the change is "from: garage" > "to: garage" hope it helps
