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.
