AVATTO S06 WiFi IR Universal Remote Controller (No Temp/No Humidity) - New Version

Device Type: misc

Electrical Standard: global

Board: bk72xx

Difficulty: Plug-n-flash, 2/5

General Notes

There's two hardware iterations of this particular IR blaster: an older version that uses an ESP01 module, and this newer one that uses a CB3S module (a Beken BK7231N module in the same form factor as the older ESP01). Outwardly, both appear identical.

GPIO Pinout

Flashing

The device is vulnerable to tuya-cloudcutter, and likely tuya-convert as well. I flashed mine with ESPHome Kickstart using Cloudcutter, then uploaded an ESPHome UF2 binary from there.

According to documentation on Elektroda, you can also use tools such as ltchiptool to flash this via serial. There are UART pads labeled on the board and easily accessible. The chip operates at 3.3v.

For use with Home Assistant integrations such as SmartIR that send raw IR commands, make sure to set the IR carrier frequency to about 38KHz. Leaving it as default may cause raw IR commands to fail to work properly.
