hi, would it be possible to add some sort of filtering for the analog inputs? adu itself works great but some values require to be filtered so that they wont flicker on the screen, not sure is that very complicated :))

you can change the update rate on the gauge/text when building the page.

Stuff like fuel level has a separate built in filtering under the config tab

filtering and displaying a random value from the range via lowered display freq is quite a bit different things.

to OP: no, you can’t filter (moving time average) values in ADU unfortunately

I know that you cant, but having that option would be great :))

What exactly are you measuring that requires filtering?  
There is a dedicated strategy for filtering the fuel level sensor.

You can also implement an IIR filter in the project tree.  
Filter strength can be set from 0 to 100.
