So I setup Hass.io on my raspberry pi (2) which has the officially raspberry pi display hooked up to it. upon booting up I get to see the HA logo for a while and then the screen goes to sleep. from any PC on the network I can hit my instance and see/use Hass.io. It would be neat however, if I could see my Hass.io instance on the pi display as well.
I am not sure how this would work, but it was just a thought. It could be surer useful.
