How do I shelve a part time device?

I have a few devices that are “part time”. Typically battery powered, they are used when I need them, but monitored in HA. Brewery temps via esp32 are when I’m brewing. iSpindel for when I’m fermenting. For the rest of the time HA has these as failed devices. Is there any way I can inform HA as to their status?

I disable my Christmas tree light entity and automations when not in use for most of the year.

Shows up like this in the entities list:

And in Dev Tools States:

Effectively they go that way by default ie entity is unavailable. Watchman then spnds most of its report telling me this as well! I was after a method of effectively hiding them (by group are area?) to excudle them completely based on a boolean switch.
