Re: keep fuel sensor value While engine on

If fuel level values change during engine off interval, then all changes will be shown as is in Wialon.

Still Wialon can affect received values in several ways:
* with expressions -- they allows to work only with current or previous messages;
* with validation -- it allows to work with current message only;
* with calculation table -- it also affects only current message.
It means, that all these methods can't help you, if engine off status will last for more than 1 message.

Still you can send us example of such a unit to support@gurtam.com and we'll try to find some possible solution for you.
Also, please,give us more details in email: why do you need such feature?

Hello Ayman,

Try to set conditions in the terminal itself.
