So after a few hours of testing everthing seems to be working fine for me .Great job towards right direction Adina!!!
The Controller name should be smaller and on top to left on settingsbutton.
Time and date maybe weatherinf there to .
The text in devices should have bold text (fat text) for more visability.
Rooms as i mentioned erlier. And to be able to make own tiles with whatever you want in it. Maybe widgets from ios
On the bottom it would be nice with fastbuttons if you have many tiles (sections)
On modebutton it would be nice to see how many lights and locks are on/off like old dashboard.
In cameras , split so you can see more cameras in same tile and if you press you get fullscreen.
See if users are in or out.
Change colours in tiles ,
One more thing… Apple Carplay… would love to be able to open garagedoor and maybe turn on a light from the screen in my car…
Keep up the good work!!
