Some time decided to put an android based tablet on the wall for my house system control purposes. And here is the result:

UI is actually web based, so it looks the same on a tablet and any other browser. Each screen displayed (multiple dashboards are supported) can be fully customized and every element by nature is small widget which can be put in any position/size described in configuration table in database. This is main dashboard for me – it shows temperature outside/inside and forecast for next five days, each button controls appropriate device (lights/heating/gate), and also I included few historical graphs which show temperature sensor readings for 48/72 hours and also heating system on/off graph.

Also I managed to set tablet wake up on motion detected in front camera, which is quite a nice feature, as whenever you pass by device it is ready for use.
