Ok, good, now log into Vera via ssh and try something like the following, using the name of an account you have set up on the NAS that can use ssh, and update it to use the ReadyNAS’s IP address - and then run any terminal command to see if it works e.g
" ...on the Vera, you should be able to: `ssh firstname.lastname@example.org 'ls -l'` (or whatever command you want) without password...."
‘ls -l’ is a command that will show you the directory/folders on the ReadyNAS .
When you have that working, try something like the following to shutdown command.
ssh email@example.com sudo shutdown -h now
When you have that working, you can then make the call via the Vera UI in a scene, by wrapping the same command in os.execute(‘command-here’)
