Im using OpenHAB for a year now.
Last week I updated my installation to 2.2 and also switches over to the Homematic binding.
Im using the simple mode so that I dont have to create dozens of items for my devices.
Everything is working greate
Today I wanted to start using groups and tags, but now Im struggling with that.
I tried to use the rest api, but every time I try to add an item to a group I get the error 405.
Then I turned off the simple mode and whenever I try to add a group to a Homematic item thorugh the paperui I get the error “item is not editable…”
What am I doing wrong?
