I had this too maybe 20 times in a year.

I tought I was because I live in a basement.

Randy, I've been noticing that I'm getting multiple Enter/Exit alerts whilst at home with my phone not moving (next to bed charging). Looking at my Geofency History I can verify the same. Why and what can I do to avoid false alarms? Mike

Without further information from Geofency and the GPS info I can't be positive. However based on my experience with other GPS devices and with Large scale GPS tracking platforms this looks like a common GPS phenomenon we call "jitter". A GPS device even the best out there have a jitter effect or "bouncing" effect. Some high end GPS units have a feature called "pinning" so when the vehicle/device is stopped the unit will pin the last lat/lon location and use it until the next "start" example "Ignition On" event happens. Cell phones/apps don't have a "ignition on" to start/stop/pin them. Apps sometimes try to compensate by pinning location when movement stops and holds onto that location data but not all apps do this. From a server/collector stand point you can do some referencing by time of receipt, last message age etc we have that with Simplex Locate for notifications.

I know this isn't an answer to your problem, but I thought I would jump in and maybe try to explain what is happening.

A couple of folks have asked about the "Approaching / Leaving" a known location which was in V1, so I've added it to the "possible" list.
If it's added to V2 it will be a trigger / condition as opposed to having HS devices.

Paul..

If you could do the approaching/static/leaving using a child device for the home location only now and then only trigger/condition without devices down the road for the other known locations, that would be great.

Thank-you sir, will be waiting with "Baited Breath"!. I know another "pain in the arse" request. Mike
