Home Automation With Raspberry Pi 2 And Node-RED #piday #iluvPi2 #raspberrypi @Raspberry_Pi
Home automation with Raspberry Pi 2. via rs-online
Node-RED is a visual tool for wiring the Internet of Things that can be run on a Raspberry Pi and allows for rapid prototyping of projects. In this tutorial we will first set up Node-RED on a Raspberry Pi 2, before creating a flow that will read a temperature sensor and control a LightwaveRF mains socket.
We will assume your Pi is already set up on the network and you can SSH into it. Ensure your distribution is up to date:
$ sudo rpi-update
$ sudo reboot
Wait for the Pi to reboot, log back in and execute:
$ sudo apt-get update $ sudo apt-get upgrade
Hardware
We will be using the following hardware:
▪ Raspberry Pi 2
▪ DS18B20+ temperature sensor
▪ 433 MHz transmitter module
▪ prototyping breadboard
▪ jumper wires (like this and this)
▪ 4.7k resistor
▪ LightwaveRF mains socket (available via many retailers)
▪ 174mm length of solid-core wire (to use as an antenna for the wireless board)
Connect the hardware as shown in the diagram below:
