@Sean Thanks. I have DDNS setup, I just prefer to keep all ports closed if possible. I also have VPN server setup in my router, but that really doesn’t help here.
From what I understand google action requires you to say to google home: “I want to speak to magicmirror” before you can trigger any command. Then the whole point with using voice to simplify is gone imo.
I will look into MMM-AlexaOnOff more and post if I succeed in connecting my google home.
