Get Weather Prediction

Purpose

This script will trigger a bash script every time device change state to on. It is use to give the weather predictions.

Dependencies - hardware / software / operating system

This script will work on all type of hardware / software / operating system.

It could be use to trigger any bash script such :

• google_voice.sh
• Any other bash script

Domoticz Setup - switches, variables, version

• Create a virtual lightswitch. e.g. : "Talk - Weather Now"
• Replace "sensor_virtual" variable by your virtual lightswitch device name. e.g. : "Talk - Garbage"
• Replace "sensor1, sensor2, sensor3, sensor4" variable by your weather station device name. e.g. : "Weather Station - Temp Humidity"
• Replace google_voice.sh by the name of your bash script
• Make sure google_voice.sh is located in : /root/domoticz/domoticz/scripts/google_voice.sh
• Make sure google_voice.sh is executable : sudo chmod +x google_voice.sh
• Change the text you want to hear. e.g. : "Prediction : Sunny"

Installation instructions

Copy this script in your domoticz\scripts\lua\ folder.
