How is geolocation achieved on these in-home devices? Is that tied to
the ~80% accuracy of general purpose IP geolocation? Do they have GPS?
Or is this done via account data in case it contains a street location?

This is different from alerts to cellphones "tethered" to a tower where
you get a better location info, even for E911 (exclude corner cases
where you are on a "mountain" top overlooking silicon Valley and lock
onto a tower further away). There you are effectively sending the alert
to the tower at a certain location and it multicasts it out to the phones
that are attached to it.
