How we built a Smart Office system based on Raspberry Pi
Good to see in a DIY-solution:<p>> <i>The light control set up is fail-safe. If something with the RPi goes terribly wrong, we could still operate the lights in the “classic” analog way.</i><p>(I wish they'd explained how they do it, but I assume they use latching relays to switch the actual lights, so RPis and light switches can work in parallel)<p>Using the chrome debugging protocol for the remote screens is also quite clever.
