Daemonize that Python script!
This post builds on a previous experiment where I made a remote control app for my outlets with a Raspberry Pi, Python/Flask and AngularJS. For the backend to be really useful, I want to make it behave as a service in Linux. It should start automatically after a reboot and there should be some control mechanism for…

RCSwitch revisited – control RC outlets with a web app
In two previous posts, I used the RCSwitch and pi-switch libraries for communication between an Arduino Uno and a Raspberry Pi. I touched briefly on the main purpose with these libraries – to control RC outlets. In this post I will dig deeper and decode the RC signals so that the remote control can be replaced…
