We now have this super useful label system, where we can put labels on about anything (automations, entities, devices), but not on tags.
This would be very useful, to react to a group of tags without the need of putting every tag as a trigger in every automation it should be used in. Just put the respective label on the tag and it triggers every automation that label is referenced in.
I hope this is something, that can be put on the roadmap soon.
I believe this is already possible, but I haven’t tried the automation part myself, so consider this untested.
You can go to the entities page and filter by tag. This will allow you to only show your tags and assign (bulk or single) labels to each tag in your entity list:
so tags can have labels, we are just missing the UI in the tag editor, then. the automation part is where is gets tricky, because there is no UI either.
for the moment, it just seems to be possible, to use a specifig tag scanned as a trigger. i probably can do some template magic, to check the label of said tag, but in the UI, setting a tag with a specific label as trigger seems to be not possible.
