I currently writing a open source Home automation in my freetime. The project is mainly a Webapplication where the user can add Datapoints. These datapoints get their data from a Raspberry PI or something else. In the near future I want to make that you can control other Elements like heating, electric socket or light switch.
Sometimes I think about creating a blog, but then I don´t know about what to write. Maybe in the near future I will make it.
