MQTT auto discovery yielded new hardware with some 80 sensors/settings. I want to group these so that I can view/hide them all at once.

Is moving the items to a room the best way to do this?

When moving items to a room, is there a way to multi-select candidates? Moving them one by one is a bit tedious...

You can go to menu setup - devices
There you can filter on zigbee2mqtt (or your gateway name) and enable/disable them if needed (green/blue arrow). See wiki page https://www.domoticz.com/wiki/Setup_Devices

Yes, that works for enable/disable. But I don't want to disable them, just stash in e.g. a room.

That unfortunately is not possible in batch as far as I know

So be it.

As far as I can see the link between rooms and devices is in the DeviceToPlansMap table in the database. So I decided to play foul...
