Computed Attributes issues after update

Yes, model wrote on "Model" field is "FMC130".

Then it's expected because io9 is decoded as adc1.

Yes, i see now. I hadn't realized that attribute adc1 is converted io9 / 1000 with one decimal... Just a question : If i remove "model" should receive io9 as before?

Yes.

Thank you so much for all your help.
