Hello,
i want to keep last fuel sensor while engine on / to use it while engine off
so
last engine on value is 5
all msgs with engine off is 5
engine on again , value 5 , 6 ,8 ,10
engine off all msgs keep 10
how to do that with sensor Expressions and validations ?
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.
