How we built a Smart Office system based on Raspberry Pi
Good to see in a DIY-solution:> 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 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)Using the chrome debugging protocol for the remote screens is also quite clever.
