Purpose
This script is used to Automate sunscreen, blinds, shades.
This script has been taken from here
Dependencies - hardware / software / operating system
This script will work on all type of hardware / software / operating system.
Domoticz Setup - switches, variables, version
Variable / Thresholds declaration.
Reading weather underground devices.
Split values from these devices.
Calculate results with thresholds
Log results to Domoticz log
Check if manual Override is active: - Less than x minutes - Only during Daytime or Always
When screen is Up/Open: - Don't close it within x minutes after open - Close screen - Optional Log to log file (conditions and results) - Optional Send Telegram notification
When screen is Down/Closed: - Open screen - Optional Log to log file (conditions and results) - Optional Send Telegram notification
Installation instructions
Copy this script in your domoticz\scripts\lua\ folder.
