Hi Julian,

Thanks for sharing this. Coming from the HA forum website (https://community.home-assistant.io/t/revogi-smart-power-strip/11273) , I´m interested on setting up the revogi plug on my HA. I was able to apply your little hack on the plug it-self, but being still a newbie in HA (yet), I´m not sure what to insert on my configuration.yaml file (and also where) to benefit from your script and use it to control the plug.
Any help would be appreciated, like an extract of your config file.

Thank you in advance for your help,
Cheers,
Marc

Hello, I just purchased one of these power strips. And their web page is really broken, but the android app works.

I just installed Hass on a Ubuntu Linux distro, using hassio_install script. This all worked.

I'm comfortable at the command line. Where would the revogi.py script sit on the power strip OS? Never using Hass before, will the power bar appear on the dashboard, or is there more intervention needed?
