Color color_light_single "Color Light Single" {homekit="Lighting"}
as far as i know you can not add them via paper ui but have to use text based config for items.
maybe in the new version, openhab3, you can do it via UI, but i have not checked this
homekit.cfg is wrong place. it has only global, not item related settings. you need to add it to you items configuration.
in my case it is in directory
/etc/openhab2/items/
the file can have any name but should have extensions .items
Thanks, that solved the immediate problem. Only cosmetic issue now it that it is called “Switch 1”. Nothing I have specified. Does anybody know how to get it to use the “Belysning nedre hall” that I have specified in the .items-file?
