I found the reason for the false theft/flatbed alert in my case by checking my telemetry archive: the car lost GPS on the road. Coordinates were stale when I parked the car. The stale coordinates were taken as the initial park coordinates, causing an alert when the GPS receiver delivered the next valid data (the actual park position).

So the bad antenna placement actually was the cause in my case, but we can solve that in software.

I've just pushed a fix (untested) for this, consisting of a) making the location module aware of parking coordinate staleness and b) lowering the staleness thresholds for the GPS metrics to 10 seconds.

Please verify.

I had the alert once with my Mii, also shortly after parking. With the module being mounted with the GPS antenna placed under the hood, I assumed that to be the cause.

I doubt it, but I'll check if any of our changes could have had an impact on the GPS movement detection.

Regarding open changes to be included in 3.2.016: sharkcow is currently working on finishing the UpMiiGo TPMS feature, it's already been tested so we'll wait for that.

Hi all,

> Twice in the last few weeks I've gotten the "possible theft/flatbed"
alert just as I was backing out of the garage. I have never received
that alert before. I hadn't posted anything yet because I was waiting to
drive the other car and see if has the same problem.

I get this too every once in a while with my e-Up. Mostly shortly after
parking, I think (and tragically, the one time I'd have needed it
because I actually _did_ get towed, I had crashed OVMS into a boot loop
just before :-/).
