Transform your RPi into a very simple connected thermostat
You need to set up a VPS for the thermostat interface. Simply put the files from the server folder on your vps, install the dependencies npm i, then run server.js. I recommend you to use forever to keep your script running.
For this project you need one RPi connected to the Internet, a Servo Motor (mine is the popular SG90), and if you want a breadboard.
Connect all theses component together, the Servo Motor is on Pin 22. Then put the file rpi.py on your card, don't forget to edit your VPS IP adresss in the file.
And voilà ! You can access the web interface on the port 1999 from your VPS IP adresss and you now control your radiator from everywhere in the world.
This is actually the strict minimum for a connected thermostat, There is so many possible features to develop :
- Increase the temperature just before wake-up time
- Turn the radiator on and off according to the position of the person (by using ifttt)
- Add a temperature sensor to adjust the setting for a desired temperature setting
- Turn off the radiator if it was at the maximum setting for a too long time to prevent fire
