Rumor has it that Google is working on a competitor to the Echo Show that will run Android... http://bgr.com/2017/09/29/google-home-smart-screen-device-leak-details/. If THAT comes to pass then it should be able to run Domotics Pad no problem (maybe a little UI tweaking to better use landscape options would be in order, but control pages should be perfect).
Domotics Pad can already stream security cameras with RTSP feeds, so it would be cool to have that auto-switch to a security camera view for doorbells and such. Right now you can only request a Control Page be shown, but switching to a security camera feed might be a good feature too.
