As my openHAB installation is on a Laptop with Ubuntu 18-04 (Server, no UI) i knew that Bluetooth (BT) was somewhat avaliable.


Add BT Support in Ubuntu

First discovery was that the Ubuntu OS had no BT installed, so we need to do this:

sudo apt-get install bluez
sudo systemctl status bluetooth
? bluetooth.service - Bluetooth service
   Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2019-01-23 18:27:43 UTC; 2 days ago
     Docs: man:bluetoothd(8)
 Main PID: 14880 (bluetoothd)
   Status: "Running"
    Tasks: 1 (limit: 3930)
   CGroup: /system.slice/bluetooth.service
           ??14880 /usr/lib/bluetooth/bluetoothd

Jan 23 18:27:43 robin systemd[1]: Starting Bluetooth service...
Jan 23 18:27:43 robin bluetoothd[14880]: Bluetooth daemon 5.48
Jan 23 18:27:43 robin bluetoothd[14880]: Starting SDP server
Jan 23 18:27:43 robin systemd[1]: Started Bluetooth service.
Jan 23 18:27:43 robin bluetoothd[14880]: Bluetooth management interface 1.14 initialized


Ok, so BT was up and running, and to make sure openHAB could use it:

sudo usermod -a -G bluetooth openhab
sudo systemctl daemon-reload
sudo systemctl restart bluetooth


Test discovery and functionality

A little testing of discovery etc:

sudo bluetoothctl

Installing Addons in openHAB

OK - so we are ready for openHAB - the sort story is to follow https://github.com/sputnikdev/eclipse-smarthome-bluetooth-binding - You need to use a 3rd party binding that s not pr. default available in openHAB.

Follow the installation, and You should be running - this should be quite clear in the inbox, it should be populated with discovered devices..:


Managing BT Devices

This is actually where it gets tricky and I am partly stucked, as I am having a hard time pairing a lot (Yes, You have a lot of BT devices in Your home) and thier MAC Adresses to real physical devices.

BT Devices has a MAC like a Network Interface, and there are several ways to discover devices and addresses:
