Differens between two variables?

Hi
I am trying to build a smarter floor heating, today i have standard thermostats and i have a concreet floor. The problem is that here in sweden we can have a big diffence between temperatur.
So if we have 10 degrese C for a week suddenly we can have -5 degrease, the i take time for the concreate floor to heat up and it gets cold inside.

So the idea is to take todays lowest temp and towmorows lowest temp, and if the differ to much i will start heating the floor in advace

To make this happen i wonder if there is a easy way using Python script to take variable A minus Variable B and insert the result in Variable C

Thanx

Replace the variable ID values in this script with the appropriate IDs for your variables.

Code: Select all

variable_a = indigo.variables[1961258112].value
variable_b = indigo.variables[389753528].value
variable_c = indigo.variables[314742858]

diff = float(variable_a) - float(variable_b)

indigo.variable.updateValue(variable_c, str(diff))  # variable values must be stored as strings


Perfect

Thanx

Perfect

Thanx

You are most welcome.
