hi, I have to calculate the perceived temperature in a home, up to now I have used temperature and humidity (from Knx) to calculate it and the node function has always worked correctly. I would also like to insert the external temperature to improve the calculation but I can't add the variable that comes from openweathermap, is there anyone who can help me. this is the code.
