 iOS version >=10 devices advertise without an extra app MAC address, nevertheless this address [changes randomly](https://github.com/1technophile/OpenMQTTGateway/issues/71) and cannot be used for presence detection. You must install an app to advertise a fixed MAC address.
 
+::: info
+The `presenceawaytimer` is also used to reset the state of the PIR/motion sensors to `off` when using HA MQTT discovery convention. If the Sensor does not detect a motion, its state will be automatically set to `off` after the `presenceawaytimer`.

 ## Receiving signals from BLE devices with accelerometers for movement detection
 The gateway is designed to detect BLE trackers from BlueCharm and automatically create a binary sensor entity in accordance with the Home Assistant discovery convention, provided that auto discovery is enabled.
