You can then drop in the resulting jar file in your addons/ folder. This will probably require openHAB 5.1.0.
Bump up the log level to DEBUG (in Settings → Add-on settings → Bluelink binding) and send me any logs from the binding. It’s not easy to get this right without being able to test it, so I will push updates to the branch when I get your feedback.
The version for CA is now available through the Marketplace (v0.3.0) - considered alpha quality since I’m not able to test it myself - testers appreciated.
(The US region should work, that has already been merged into the openhab repo.)
