I have a temp sensor on my DataLogger (WebControl Server). I allready pushed successfully the data to my local raspi emoncms installation, but the data needs to be corrected by a slope (multiplier) 0,0929 and an Offset of -30.7793.
How can i do this as the importer just takes the value given by the WebControl Server.
So to get correct temp shown i need to multiply with 0.0929 and -30.7793 Thnx for you help
I found now the ProstProcessing, but this is not working for formula as it allways shows an error (f8 is the correct feed id).
STOPPING could not understand your formula SORRY…
