How much electricity are we using? A colleague of mine has made a simple circuit attached to an Arduino to answer that question. Furthermore my parents were also interested in monitoring their electricity usage. So I decided to introduce my father into the world of Arduino for his birthday.
For the new bathroom in my home I also installed a Velux window, complete with an electric roller shutter. Of course I wanted to connect this shutter to the rest of my home automation system. Velux has options for this, but I wasn’t looking forward to integrating a vendor specific system to my existing setup. I already had Z-wave installed so I made a small project to connect the Velux shutter to a Düwi Z-wave module.
