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).<br>
<br>
So the bad antenna placement actually was the cause in my case, but
we can solve that in software.<br>
<br>
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.<br>
<br>
Please verify.<br>

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

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