I’m having trouble getting third party geofencing solutions to work (ie. OwnTracks with Presence and Location) - see [APP][Pro] Location and Presence (Owntracks) - #385 by Michael_Stephens .
If there was just a little bit more control over the built in presence geofencing, specifically the ability to define the radius, I wouldn’t need to worry about third party solutions.
I would certainly vote for the suggestion to allow a user configurable radius
