Build your own Wifi Smart Thermostat.
It is easy, it is economical, and it will help you save money heating your home!
The project explained briefly
Smart Thermostat Android app
If you have an old smartphone or tablet forgotten in a drawer, a box or a dark corner, you can recycle it and use build a Wifi Smart Thermostat! The main actor of this project is the Smart Thermostat Android App. It is designed to control a home heating system, and works with devices as old as Android 4.1. The app is available in the Play Store.
The temperature sensor
The second piece of this project is the temperature / humidity sensor. We are working to support different temperature sensors, but at this moment you will need an ESP32 microcontroller, and a DHT temperature sensor. The sensor will read the temperature and humidity of your home / room, and serve this information to the thermostat. You can have multiple temperature sensors if you want (for example, one for each room of your house).
Of course, you will need something to turn on and off your home heating system (for example, your boiler). For that you will need an ESP32 microcontroller and a High Level Triggered relay will do the work! All this components are very cheap, and easy to configure.
