Log and Graph 24V Thermostat Events Using a Raspberry Pi

F20C7JLI4SCE23K MEDIUM

This handy tutorial from langelgjm shows you how to keep track of thermostat use with your Raspberry Pi.

There are a lot of Instructables that show how to make a thermostat. But what if you already have a thermostat, and you want to log or monitor when it turns off and on? This Instructable shows how to use an optocoupler to obtain logic-level DC voltages from a common household programmable thermostat that connects to a 24 volt AC heating and cooling system. It also includes a temperature sensor, and code suitable for running on a Raspberry Pi to log and graph thermostat status, events, and temperatures.

WARNING: Working with electricity can be dangerous. Before continuing, be sure you have adequate understanding and skills to complete this project safely. While I’ve done my best to make it safe, I am not responsible if this project fries your thermostat, Raspberry Pi, HVAC system, your cat/dog, or burns down your house.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
