This dzVents script is used to switch the wireless network on RT-AC88U-2E68 based on the state of the domoticz 
device used to trigger this script.

The script use io.popen to trigger a nvram and a service restart command on a remote system via ssh 
(the router must be accessible by the user that is running the domoticz service, via password-less 
SSH (with public / private key setup)

Before activating the script:
    Read the GETTING STARTED section of the dzVents wiki. 
    Change the values in the script to reflect your setup
