Calculate Delta T of two temperature sensors with lua

[Mela]

Hi,

Is there an lua expert that can help me, with this?

In domoticz I have 2 temperature sensors, and a dummy Delta-T, I like to make a lua script that uses the two temperature sensors to calculate Delta-T and show me the calculated value in my Dashboard.

I have no lua experience, I always used Blockly to make things work, but blockly have no calculation possibilities.

Thank you.
