By default, the ESPHome tracker runs in active mode. Many integrations require an active scan for discovery. The following remote adapters are supported:ĭevices with an ESP32 chip running ESPHome must enable the bluetooth_proxy component and be added to Home Assistant before advertisements are forwarded. The number of remote scanners is limited only by the performance of the host system. The Bluetooth integration supports receiving advertisement data from external adapters for devices and sensors that do not need an active connection. If multiple instances of Bluetooth are configured, choose the instance you want to configure.From the configuration menu select: Devices & Services.Browse to your Home Assistant instance.Options for Bluetooth can be set via the user interface, by taking the following steps: Many integrations require active scanning and may not function when scanning is passive. Passive Scanning on Linux can be enabled in the options flow per adapter if the host system runs BlueZ 4.63 or later with experimental features enabled. Integrations that have followed the Best practices for library authors will automatically connect via the adapter with the best signal and failover to an active adapter if one becomes unavailable. The following methods are known to work to add multiple adapters: Place adapters far enough away from each other to reduce interference. Support for multiple local Bluetooth adapters is available on Linux systems only. tp-link UB500 - Frequent connection failures with active connections.tp-link UB400 - Frequent connection failures with active connections.If you experience an unreliable Bluetooth connection, installing a short USB extension cable between your Bluetooth adapter and your Home Assistant server may improve reliability. Installing an adapter for the first time may require multiple restarts for the device to be fully recognized. Some systems may not come with Bluetooth and require a USB adapter. On Debian based host systems, the sudo apt-get -y install bluez command will install BlueZ.
