WORKING SCRIPT
Use this script if you want to change the colors of your Hue lights according to the outside color temperature. This script is based on the EdiSun project.
So, please feel free to use and experiment with the script!
To use this script follow these instructions:
A. Create a virtual sensor, type: custom, with name: 'Mirek' (case sensitive) and label: 'mirek' (see Dummy in hardware).
B. Create a virtual sensor, type: switch, called "HueSun" to toggle the script (or any other name will do, you can change this in the variables in the script)
C. Create a virtual sensor, type: switch, called 'oneTimeTrigger' (any name will do)
D. Get an API key at
https://openweathermap.org/price
E. Make sure you have installed the socket library:
http://www.domoticz.com/wiki/Upload_ene ... et_library
F: Change the variables in the code and activate the script 'Time' based
G: Have fun!
Please tell me what you think of it!
