Thermostat Servo Cover
thingiverse
I wanted to install a smart thermostat in my house to save on heating. But I rent and the heating system is line voltage, so replacing the thermostat and messing with the electric system was not the best idea. So what better excuse to to do some 3D printing and automate the thermostat that's already there? This model is a duplicate of the cover for the thermostat, but with mounts for a servo. Also included is an adapter that connects the servo to the thermostat axle. The servo can then be connected to an ESP8266 and be remotely controlled from the internet. I used an [SG92R servo](http://www.towerpro.com.tw/product/sg92r-7), a [NodeMCU ESP8266](https://www.amazon.com/Heltec-Automation-HTIT-W8266-internet-development/dp/B074373KTY/ref=sr_1_2_sspa?ie=UTF8&qid=1507675983&sr=8-2-spons&keywords=esp8266+oled&psc=1) board and a [DHT22](https://www.adafruit.com/product/385) for telemetry.
