The towing notification only works when the ignition is off. This notification alerts you that your vehicle has started moving with the engine off. Which means someone’s towing her. So yes, that’s right, you will only receive a towing notification when the ignition is off.
To detect device disconnection, we recommend using a notification with the “No messages” type. It will notify you when no messages were received from the device in the interval of 5 minutes, which means that it was most likely turned off, or something happened.

As for idle detection, unfortunately, we do not have such a function. Tell me, would you like to receive idle notifications? That is, when the vehicle has an engine running, but it does not move for some time?
