thanks Yveaux That seems like the way I will have to go. I will work on it.

@mfalkvidd Thanks very much mfalkvidd. My DS18B20 feeds a Paladin diverter which transfers solar energy to my hot water. I don't have access to the code in the Paladin. Can I put an arduino programmed to raise the indicated temperature by 5 degrees between the sensor and the Paladin diverter?

This is my first post and I am not sure I have put it in the right place. I want to increase the reading of my DS18B20 by 5 degrees. For example it is now reading 43. 2 degrees C and I would like the one wire output to be 48.2 degrees. Is this possible?
