I started mucking about with ESPHome yesterday and setup a WROOM with an AHT22 temp/humidity sensor. Running the wizard and adding the configs is easy-peasy. I started to have issues as soon as I wanted to flash.

  • If the AHT22 is plugged in, I cannot flash the device over USB.
  • I can check the serial logs once the device is flashed and then plug in the AHT22 once the device is booted and get readings, but
  • Once I unplug the ESP32 from the serial port and plug it into a power supply, I got nothing. No network activity at all.
  • Unplug the AHT22, plug into the power source, wait a few seconds, plug in the AHT22 has seemed to work correctly this morning and HA is pulling data but I tried that last night a few times and it didn't work -- so unsure why it's working this morning other than strange timing when I'm plugging the thing back in.

I am using the basic esp32dev firmware, which I am assuming works because it DOES work, eventually, but I'm not confident I'm using the right base but I cannot figure out which one to use.

I'm glad it was helpful. They are great little controllers and ESPHome makes them so accessible for people like me who don't really want to write code manually.
