An Arduino library for controlling Mitsubishi heat pumps over the CN105 connector using serial communication. It lets microcontrollers like ESP8266/ESP32 read and set heat pump settings, room temperature, and installer functions, commonly bridged to MQTT and home automation platforms.
Use cases
- control a Mitsubishi heat pump from Home Assistant
- read room temperature from a mini-split via CN105
- integrate a heat pump with MQTT and OpenHAB
- replace the KumoCloud remote control with local WiFi control
- automate HVAC settings with an ESP8266 or ESP32
- send and read installer function codes on P-series air handlers
When to choose
- you have a Mitsubishi mini-split or heat pump with a CN105 connector and want local, cloud-free control
- you are building a DIY ESP-based thermostat or automation bridge
- you want to integrate the unit with Home Assistant, OpenHAB, or MQTT
When to avoid
- your heat pump is not a Mitsubishi model or lacks a CN105 connector
- you want a ready-made consumer app rather than writing Arduino firmware
- you need installer function support on units other than PVA/P-series, which is untested
