5v piezo buzzer12/5/2023 ![]() Leverage as much of the existing Arduino OSS code ecosystem as possible, keeping the project tightly scoped to its problem domain.Build a device that expands the surface area of a home automation system, letting it gather more data, take more user input, and provide more feedback.Provide hobbyists with a reference for Arduino code with that kind of structure (I had a hard time finding it for end projects, only libraries).Structure this project into discrete objects to make iteration, maintenance and enhancements easy.Use easy-to-repurpose IR, instead of a manufacturer-specific serial connection.Make a heat pump controller I don't hate using.Toggle your heat pumps from any room in the house, or even while you're away. Program automations using Home Assitant, not miserable rubber buttons like a VCR. The chunky dial is easy to press without looking. Through a TFT screen, readouts are visible any time of day. Set fan speed by pressing the center button, then turn the dial. InterfaceĬhange to heat mode with the bottom button, cool mode with the top. Note: you will need PlatformIO to get started. No signal analysis or reverse-engineering required. Thanks to integration with IRRemoteESP8266, you can make ThermTerm work with your own heat pumps by writing a few lines of adaptor code. Out of the box, ThermTerm supports Mitsubishi's infrared protocol, since that's the system I have. Additional sensors pipe temperature, humidity and light data, for statistics and automation. ThermTerm solves all the problems I've had with these physical controls, while integrating the heat pumps into Home Assistant via MQTT. In theory, you can program schedules for your heat pumps, but in practice the remotes are too frustrating to use for that. They're clunky and hard to read, especially in low light. They're energy efficient and the fastest way to heat or cool any room.īut I've always hated the remote controls that come with heat pumps. ThermTerm: an open source heat pump controller and home automation terminal, built on ESP32Ĭontrol heat pumps manually or remotely via MQTT/Home Assistant.
