Perhaps use as formula:

Code: Select all

%value%/100

I think it could be a bug that formula isn't working for the mqtt import plugin..? You might want to report it on GitHub.

You should see the computed value (after processing by formula) in the device overview tab.
And can you use real screenshots for the web-interface images, these photo's are too small and too unclear to see.
