Temperatures over 100 Celsius

I'm smoking ribs and the temperature should be about 100 Celsius. I'm using Weber wireless thermometer and the problem is that Tellstick shows temperatures only with two digits. Is it possible to write logic somewhere that temperatures between 0-50 is interpreted to 100-150? That way it would always show right temperature between 50-150 which would be perfect for me..

This could be done with Plugin.

Yes, this can be done using the built in function Value Mapping :) (No plugin is required)

Open Data Source Options and select the Presentation tab.
Under Value Mapping, select Linear mapping for calibration/conversion

Then add the following rows:

Source Value / Presentation Value

0 / 100
50 / 150
50.1 / 50.1
99.9 / 99.9

Source values from the temperature device will be converted according to the table. Values are linearized in between points in the table. Examples:

0 -> 100
10 -> 110
50 -> 150
60 -> 60
90 -> 90

Nice solution Tomas.
Dident know Value Mapping was that "smart".

Wau, this is really neat! I was thinking linear mapping could be the solution, but I would never have figured out the correct rows. Thanks!

You are welcome :) Good luck with the barbeque.

With the Value Mapping you can be quite creative and use it as a solution for various use cases.

I have tried to do this, but i cant manage. The difference is that my data source is through OneWire via the OnewirePlugin. How to change the presented value for this? I cant make anything change with mapping.

Thanks.
