Traccar supports output control command and custom command. If your device supports it, one of those options should work in Traccar.
Whats the sms message that you send?
Hi, everyone.
Does Traccar allow us to operate the vehicle's doors if the tracking device installed supports this function?
The device has a programmable key ( KeyDIY) programmed to the car's Immobiliser. The key is triggered by a SMS message to open or close the doors.
