Hi, thank you for the project, i just got my chipset delivered, i would like to your version install esphome on it. Hiw do i go about fkadhing the compiled firmware on it is there a web update feature or does it have to uploaded using uart/serial?

I suppose it depends on the details and status of the board you're hoping to flash.

I had boards assembled with off-the-shelf ESP32 chips which I flashed initially using UART pins 1 and 3. I connected the board via a USB TTL serial adapter and caused the board to enter programming mode by shorting pin 0 to ground. Then I used ESPHome to flash over serial. Your board may be different, but most I've encountered allow serial programming via this method.
