Smart Old Relic Thermostat.

This is a DIY (do it yourself) project, to build a very cheap Smart Thermostat to control your home heating.

You will need an old Android 4.+ smartphone or tablet, the typically device that is forgotten in a drawer. This device will act as Thermostat and control your home heating system.

Additionally you need a couple of ESP32 microcontrollers, an DHT Sensor and a High Level Relay..

You can find all the details of the project and the assembly in our web page:

The project is on an beta stage, but is already functional, and you can test it if you are interested. Your feedback will be very appreciated.

Please, before leaving a bad review because you think this app does not work, try to understand that this app is only a piece in a more complex project, and you will need to buy extra hardware to make it work.
