I also tried those things. What got me going, was the REST API. So, just send a PUT request to http://:/rest/items//tags/Lighting to set a tag called “Lighting”. I use the “Advacned REST Client” available as a plugin to Chrome to do this, but you can also go to your OpenHAB-server to URL /doc/index.html, and use the built-in REST client. It worked for me, and I now have tags successfully set, and HomeKit working
