Using a N810 for controlling home automation...
One option is LinuxMCE.

From www.linuxmce.org
"LinuxMCE is a all-in-one open source solution that seamlessly combines:

* Media & entertainment with a server for music and video, plus a PVR (like TiVo or Sky+)
* Home automation to control everything from lights to heating with a touch-screen tablet or your mobile phone
* Phone system with video conferencing
* Security system that feeds live video to your mobile device during a security breach

LinuxMCE builds on the networking capabilities of Linux to create a home automation/multimedia/communication network. No other operating system has this capability."
