I noticed many people change Tuya modules to ESP8266.
AHT20 (i2c) - connected to WB3S via MCU on uart
I offer my code:
There is a button to check the received code.
And send via ESPhome (code) or automation

action: esphome.devices03_send_ir- I first flashed via UART in Open B K7238_Q Ю_1.18.136.bin via BK7231GUIFlashTool-v32 (When flashing, via uart you need to short-circuit Pin1 - Pin9 (CEN-GND);
- From ESPhome firmware “bin” via Itchiptool v4.12.1 (When flashing, via uart you need to short-circuit Pin1 - Pin9 (CEN-GND));
- then it is esphome updated via WiFi.
