AVATTO S06Pro WiFi IR Universal Remote Controller

General Notes

There's two hardware iterations of this particular IR blaster: with and without AHT20 Sensor, and a simple one that doesn't have additional sensors. Outwardly, both appear identical.

GPIO Pinout

Pin	Function
GPIO8	Blue Status LED
GPIO26	Remote Transmitter
GPIO7	Remote Receiver
GPIO6	Reset Button

Getting it up and running

This device needs very likely to be flashed manually. Tuya-convert didn't worked for me. I have powered the device with a mobile charger during the flashing procedure, as the used serial cable sets to logic level based on the input voltage. Which is 3.3V in this case. To enter a BOOT mode short-circuit the CEN and GND outputs

Serial	CB3S
RX	TX1
TX	RX1
RST	CEN
3.3V	3.3V
GND	GND

Flashing

# Create a backup of the original firmware
esptool.py -p /dev/ttyUSB0 -b 230400 read_flash 0x00000 0x100000 avotta_s06Pro_original_firmware.bin

# Erase the flash
esptool.py -p /dev/ttyUSB0 erase_flash

# Upload the esphome firmware
esptool.py -p /dev/ttyUSB0 write_flash -fs 1MB 0x0 ir_remote.bin
