Group of person entities is Away, even though all persons are Home

The problem

I have created a group of Person entities (called Residents) that I use for automating certain things based on the presence of people living in my home (me and my girlfriend).

This has been working fine up to a point somewhere in the last 2-3 months (not sure when exactly): when one or more person entities has the state Home, then the group also shows the state Home. Lately, however, this has been completely off. Often, the group is Away even though one or both of us are home (also registered as such by HA). You can find an example of this in the attached screenshot. Has something changed recently regarding this part/integration of HA?

(I have recently used a workaround by creating a binary_sensor entity to replace the group entity, but I’d still like to resolve this since I feel a group entity is a more elegant solution)

I don’t think it’s been fixed yet

Yup, just ran into this issue, as soon as one my people entities becomes “not_home” the group becomes “not_home”. I tried both setting “all: false” and removing the option completely.

Or, I created a group of device trackers, since each of my “people” only have one device tracked
