Hi,
I’m quite new to Home Assistant experience and just have started to get a grip on automation but I have problem with setting groups (probably quite trivial) but stopping me from developing further my home automation.
I’ve tried everythin and no matter what I put in groups.yaml it doesnt seem to affact the interface. Even below simple, sample code doesnt seem to work. Does anybody have any idea what can be reason for it and how to fix it?
