Small icon beside Device name
It shows ignition icon if device reports the ignition.
all the devices support it, but not all of them show it, some show a red (!), as an alert, some show the engine sign.
Once again, it shows whatever your device reports. Support and actually send are different things.
In 5.3 server, i cant see the icon beside the device name for all. it aonly show that the ingtion on for some of the devices.
