Winter is soon to arrive in Sweden and the amount of daylight is decreasing every day. Thus it’s time to set up some extra light sources indoors and outdoors. I have been using my web app for remote controlled outlets (link) for some months now, but with the additional light sources needed for this time […]Read More Preparing the remote control app for Christmas
As described in some earlier posts, I have a setup at home with IoT devices that publish measurement messages to a Raspberry Pi via MQTT. The RPi stores the data in a database and also forwards the messages to a cloud service (Adafruit IO). In this post I have made a self-hosted data visualization web app […]Read More A web app for IoT data visualization
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 […]Read More RCSwitch revisited – control RC outlets with a web app
In this post I will show how I have used a Raspberry Pi as a relay server that can be controlled via a web app on e.g. a mobile phone or via REST calls. The system consists of: A Raspberry Pi 2 with Raspbian A set of relays connected via the GPIO pins on the RPi […]Read More Control your home with a Raspberry Pi and a mobile phone
I’m totally addicted to Sweden’s public service radio, especially the SR P1 channel that is almost always flowing from our speakers at home. Programs that I miss, I catch up with via the excellent collection of SR podcasts. When I recently decided to refresh my knowledge in AngularJS, I was looking for a ready-to-use backend […]Read More Hello SR open API!
