I have a rule that sends me once a day a battery status report. The rule loops trough a group that contains all battery items. To apply the right check on a specific item i added to every battery item metatdata that tells me if it is just a switch or a level.
My question ist now: Is it possible to get a list of all items with a specifiy metadata namespace? With this i could throw away my battery group and use only the metatdata?
