turn engine off

Does it have feature, or be added to turn Motor Engine Off with some gps models like remote-cutoff fuel in devices like WeTrack2?

Yes, Traccar does support engine lock/unlock commands.

How is this achieved ?
What is command for it ?
Depends on model device ?

Thanks

Depends on the device model. Command name is pretty self-explanatory.

WeTrack2 stop engine command exists.

Can traccar send alert for vehicle leaving geofence, can it mark it on report?

Does WeTrack2 work on 3GNetwork ?

How to configure WeTrack2 into traccar ?
