Counting Based on Temperatur

Hi All,

I have three temperature sensors on my hot water cylinder. Most of the hot water is heated by excess solar generation. However, when the gas does heat the hot water, I would like to count the days.

Is it possible to use the temperature input and create a feed that counts the days Temp3 has gone greater than 55C.

I would like to create a metric that shows the days heated by Gas vs Solar.
