Home Automation HAT
Home Automation HAT is a Home monitoring and automation controller HAT for the Raspberry Pi that can control up to 2 appliances/devices on a load of 250 VAC/7A, 30 VDC/10A, photo-coupling isolation Optocoupler EL357NC, allowing users to safely control high voltages or current devices. Home-Automation HAT makes appliances smart, which users can operate via the PiRelay app on their electronic device.

Installation
Raspberry Pi (Using PiRelay App)
PiRelay is an Android app you can use to Switch or Pulse the GPIO Pins of a Raspberry Pi connected to Relays. To use this app you will need to setup your Raspberry Pi and Relays. App Download link: https://play.google.com/store/apps/details?id=com.jasonfindlay.pirelaypro
- To setup PiRelay on Raspberry Pi, run the below commands one by one. Must complete all commands to make it work with Raspberry Pi.
Commands to Install: WiringPi, Apache, PHP & Download the GPIO PHP File
sudo apt-get update
sudo apt-get install wiringpi apache2 libapache2-mod-php -y
sudo wget https://pirelay.jasonfindlay.com/downloads/gpio.dl
sudo mv gpio.dl /var/www/html/gpio.php
Setting Up Your Android Device
- Download Pi Relay app from the Play Store here: PiRelay App Download
- Make sure your Pi and Android Device are on the same network. Then in the app settings, you can define a custom Server URL. This is the network path to your Raspberry Pi. The default path is " http://raspberrypi/ ", however, you can define an IP address or a custom URL.
- To turn on/off relays, Use Pins as Wiring Pi pinout shown above in Pinout table.
