Add a Filter Helper to filter out bad readings

Month of "What the heck?!"

Some sensors give realy strange reading like after a device reboot their count goes to 0 or if a seonsor is not avaible it might go to 0 then back to the proper value. If we could add a filter helper that we could filter the values coming from the sensor. IE data cannot have changed more than X% or X value. When Sensor is not available keep reporting the last value.

There is a filter helper, does this not work for you?

I had no clue, is this by the config only? is there no UI for this?

Not yet, it’s in construction so for the moment it’s unfortunately yaml only.

Is there a proper way to remove this form the WTH category? As my inability to RTM on filters makes this posting moot!
