This may be usefull,I have been using this script to plan my central heating system for the last two years now (flawlessly
). It only publisches setpoints for two rooms based on a time and a day of week. It also calculates when the heating should turn on in order to reach the temperature on the desired time. It supports manual mode.(Manual mode will override at the next planned time in case someone forgets to put it back)
You can use the setpoints in another script to control your heater.
You will have to adjust the script for your own use and it most probably can be optimised.
You have to create two selector switches:
Livingroom periods: Wake, Home, Comfort, Away, Sleep
Heating Mode: Off, Normal, Vakantie, Weg, Thuis (Thuis is for Thuiswerken)
Code: Select all
