ESP32 Bus Pirate is an open-source firmware that turns your device into a multi-protocol hacker's tool, inspired by the legendary Bus Pirate.
It supports sniffing, sending, scripting, and interacting with various digital protocols (I2C, UART, 1-Wire, SPI, etc.) via a serial terminal or web-based CLI.
Modes for:
- HiZ (default) - I2C (scan, glitch, slave mode, dump) - SPI (flash, sdcard, slave mode) - UART / Half-Duplex UART (bridge, read, write) - 1-WIRE (ibutton, temp sensor) - 2WIRE (smartcard) / 3WIRE (eeprom) - DIO (Digital I/O, read, pullup, set) - Infrared (device-b-gone, send and receive) - USB (HID, mouse, keyboard, gamepad, storage) - Bluetooth (BLE HID, scan, spoofing, sniffing) - Wi-Fi (scan, AP, connect, sniff, deauth) - JTAG (scan pinout, SWD) - LED control (animations, set LEDs) - I2S - CAN
However, the entire implementation is new, it's not a copy

this USB ESP32 module which works out of the box on Midea-produced units (Carrier, Electrolux, Pioneer). I have a few units that are other generic brands which apparently are rebranded "Aux" brand units, so I re-flashed the ESP32 board above to work with Aux units by doing `brew install esphome` and then `esphome run auxminisplit.yaml --device /dev/tty.usbserial-210` where auxminisplit.yaml is https://gist.github.com/jasongill/35a13e458b6d109ca2bbefeab4...
That worked perfectly for me and should cover like 90% of all minisplits (Midea and Aux make a ton of brands units), let me know if that works for you.
Certainly could be the case. I've spent more time than I want to admit chasing down what was ultimately a loose wire.
For what it's worth, you can get a cheap ESP32 module and basic IR sensor modules for a few bucks on amazon [0]. As long as you have a basic USB <-> TLL/Serial adapter, you should be able to install ESPHome on that. The module that's on that particular board does not have a ton of room so keep the ESPHome config simple and to the point.
It's a few dozen lines of yaml total to get a basic IR signal decode/dump tool: [1]

I live in New Zealand where we pretend that it’s never particularly cold or particularly hot. This might be a factor in how sloppy all the installs seem to be.
Nothing; there is something about my AC and the badly hand-assembled ESP8266 and IR transmitter I made that doesn't work.
I recently found a remote that doesn't to the 30kHz modulation-- good luck to me controlling that with anything.
