Grouping zones (self.homeassistant)

Is there any way to group zones together? I would like to define zones that are not necessarily circular in shape. I can accomplish what I want by overlapping several of them, but I really want to group them together and treat them as one zone. Is this possible?

I suppose I could probably script up a template trigger...

I get what you mean and yea I don't think you can easily use groups for that.
Zones have a several things going on.
In no particular order:

A zone's state is the number of people in it.
Zones can be used as enter/leave triggers in automations.
A person's state becomes the name of the zone when they're in them.

Making a mock entity for #1 is easy enough, a helper number thing whose state is the sum of the group members' states.
The other stuff is more complicated.
#2... Might be easier to add the different zones as multiple triggers, which might be a pain to manage. But then, I assume you'd also want to ignore whenever someone moves between zones in that same group.
#3... idk, if it's just for displaying purposes in that person's "badge" thing, just use the same display name for all zones in group. If it's for use in an automation, then you probably need to duplicate everything again.

Might be easier to implement polygonal zones than group normal ones.

I think nodered might already have that geofencing feature.

There's a bit of discussion in here: https://github.com/home-assistant/architecture/discussions/1014

In the current version of Home Assistant, if a person is in two overlapping zones, what happens? It's possible to be in that state today.

I suppose it doesn't really matter though. I've named all my home zones similarly: home1, home2, etc. It would be easy enough to check for a zone where the object_id starts with "home"

Good question, I'd guess it would be the closest to the center of whichever zone.
I haven't tested them, but if they work, it'd be easier to use non circular zones than deal with multiple overlapping ones.
