How to Build Smart Heating with Raspberry Pi

RaspberryPi

Raspberry Pi

IOT (Internet of things) is common notion these days but what really you can do with it? what first thing you want to connect? how you can make something smart if it isn’t smart?  i.e Smart Heating, what are the pros and cons?

You only have two options, one buy off-the-shelf commercially available product (there are tons and tons of comparison between all commercially available solution so i m not going to go through any of that), second you could spend less and have fun building things yourself.

Fancy second option? then Let Get Started!!!

This Project is based on credit card size single board computer called Raspberry Pi, whole systems is presented using Apache web server, all information is stored in MySQL database. Python script is used to log temperature sensor data using One wire DS1820 temperature sensor, most of the code is written in PHP.

Before we deep dive into this project something very important: PiHome comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law. DO NOT MAKE ANY CHANGES TO YOUR HEATING SYSTEM UNTIL UNLESS YOU KNOW WHAT YOU ARE DOING, contents provided here are for information and education purpose only, I take no responsibility for any loss or damage to you or your property.”

Smart Home Gateway from NRF24L01 to Ethernet/WiFi

All nodes i.e temperature sensors, boiler relay module, zone relay module etc. are scattered around the house that are responsible for controlling light, heating and other IOT devices serves very little purpose if we can not communicate with them or pass some instructions. Most of the time these devices are battery powered and even ones with main powered don’t communicate through home WiFi and for the battery powered nodes WiFi isn’t the option due to the fact how WiFi works…
