=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 | 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.
