Fuel Level Notification with Engine ON/OFF

Yes you can all you have to do is create them under unit properties click on new and add ignition On & OFF

What device are you using?

You could look a adding a custom field for the fuel level and then add the custom field to the notification text. The custom field would need to be able to get the fuel level value from the parameter. Only alternative is to send all of the sensor values in the message.

It would be good if Gurtam added custom sensors as one of the items that can be added into te message.

where is the problem? you create two notifications (one if engine goes on and one if engine goes off), than you add in notification text this "%ALL_SENSORS%" and thats it.
(i think there is also a parameter for adding one specific sensor, read the manual for it)

Nice Post on this topic

You should check mileage counter settings. Activate option "Auto". If counter is set on "Mileage sensor", "Relative odometer" or "GPS + engine ignition sensor", please, check mentioned sensors were added.
