Hm, maybe this will finally let me network my IR-controlled AC units. There are a bunch of ESP/IR projects, but for some reason I haven't gotten them to work (pretty sure it's a problem with my hand-assembled hardware, in fairness)

What is it about AC that makes it impossible to control?
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.

The firmware supports about 83 IR protocols, but even with that, it's not mandatory that it works with all existing devices.

If it can run at the right speed or frequency or whatever, I'm perfectly happy for it to work purely by recording and replaying signals that I give it with my remote.
See here for a very large database of IR signals that works with the firmware.

ESPHome is good for that.

It can be informative to drop an oscilloscope probe on the transmitter.
I recently found a remote that doesn't to the 30kHz modulation-- good luck to me controlling that with anything.

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
