Thermostat based on raspberry pi and an atmega328 with lm35z temp sensor. Heat your house and control it remotely using web app!
Print the parts. Put a raspberry pi and a pcb inside to control your house central heating. I've finished it but need to draw out the schemetics for the raspberry pi add-on : it's basically an atmega 328, lm35 + 2 buttons and a led that is connected with a cd4050 to the raspberry pi that serves a mobile webpage for turning on/off the heating.
I added a seperate file for the buttons as the original ones needed glueing and did not fit well. The ones with stops fit snuggly and stay in place without glue.
I got power by using one of the unused cables from my doorbell phone/speaker ;). The only issues I have left is moving the led a bit upward so that it sits under the hole in frontpanel and adding the cd4050 buffer chip to communicate with the pi and add wifi stick to the pi...
