I have basically the following systems:
Homematic
Philips Hue
iCloud (iPhone GPS…)
Fritzbox
Samsung TV
OH is running on a Raspberry Pi.
With these components I control the temperature when we’re at home and absent, the lights, and the rollershutters will follow soon.
Here is how my basic UI looks like:
And in our kitchen I have an old iPad 2 running HABpanel:
After seeing here some pictures of HABpanel, I think I might change my colors or something, but that’s not the first priority 
Also, I created the house in 3D using Sweet Home 3D. Unfortunately it doesn’t run on the old iPad, but does very well on a computer 
It’s integrated in HABpanel.
Here’s how it can be done: (Proof-of-concept) Interactive WebGL view with HABPanel & Sweet Home 3D!
I have some things left to do, but after more than a year of building rules and UIs I’m pretty happy with it so far
Cheers,
Viktor
