@Mokamobile You download latest build from here Releases · themillhousegroup/openhab2-addons · GitHub. The jar file you downloaded should be copied to shared folder
\\<openhab-hostname>\openHAB-addons\
e.g. through Windows Explorer.
You wrote you use OH3, so please make sure you find latest build for your version 3.0, 3.1 or 3.2b. Latest 3.2b1 should also work with 3.1.
Then access OpenHAB’s Things section, add new Thing with “+”, select “Broadlink” binding, use “Scan” to auto-detect your device.
