# Bluetooth Binding
![](/logos/bluetooth.png)
This binding provides support for generic Bluetooth devices.
It has the following extensions:
- AM43
- DaikinMadoka
- Generic Bluetooth Device
- Bluetooth BlueGiga Adapter
- Bluetooth BlueZ Adapter
- Bluetooth Roaming Adapter
- EnOcean BLE Binding
- Ruuvi Tag
- Blukii
- Govee
- Airthings
# Bridges
In order to function, this binding requires a Bluetooth adapter to be present, which handles the wireless communication. As there is no standard in Bluetooth for such dongles resp. chips, different adapters require a different implementation. This is why the Bluetooth binding itself does not come with any bridge handlers for such adapters itself, but instead is extensible by additional bundles which can implement support for a specific adapter.
For Linux, there exists a special bundle which provides a Bluetooth bridge that talks to BlueZ. This should be the best choice for any Linux-based single board computers like e.g. the Raspberry Pi.
# Supported Things
The base bluetooth binding only supports a single thing type. Additional thing types are available through bluetooth extensions.
Thing Type ID | Description |
---|---|
beacon | A Bluetooth device that is not connected, but only broadcasts announcements. |
# Discovery
Discovery is performed through the Bluetooth bridge. Normally, any broadcasting Bluetooth device can be uniquely identified and thus a bridge can create an inbox result for it. As this might lead to a huge list of devices, bridges usually disable this behavior by default.
# Thing Configuration
All bluetooth thing types require a configuration parameter address
, which corresponds to the Bluetooth address of the device (in format "XX:XX:XX:XX:XX:XX").
Other configuration parameters may be required depending on the bluetooth thing type, look at the documentation for that thing type for details.
# Channels
Every Bluetooth thing has the following channel:
Channel ID | Item Type | Description |
---|---|---|
rssi | Number | The "Received Signal Strength Indicator", the RSSI (opens new window) |
# Full Example
demo.things (assuming you have a Bluetooth bridge with the ID bluetooth:bluez:hci0
):
bluetooth:beacon:hci0:b1 "BLE Beacon" (bluetooth:bluez:hci0) [ address="68:64:4C:14:FC:C4" ]
demo.items:
Number Beacon_RSSI "My Beacon [%.0f]" { channel="bluetooth:beacon:hci0:b1:rssi" }
demo.sitemap:
sitemap demo label="Main Menu"
{
Frame {
Text item=Beacon_RSSI
}
}
