I got a few of these boards from aliexpress.
Was able to connect using USB to my laptop then flash using esphome web. It successfully install, but after install does not connect to wifi, and checking logs shows error message “wrong chip id 0x3288”.
I tried all the board types mentioned in ESP32 board from Aliexpress yaml config (mhetesp32minikit, wemos_d1_mini32, ttgo-t7-v14-mini32, esp-wrover-kit), and all have the same problem. Any ideas for how to fix this?
Can u post the Yaml from ESPHOME for this board?
esphome:
name: theater-couch-new
friendly_name: Theater Couch New
platform: esp32
board: wemos_d1_mini32

captive_portal:
If you have the ability to run esptool.py in the command line on your laptop, run the “flash_id” option. This will tell you what chip is there.
python esptool.py -p COM? -b 921600 flash_id
The result will help tell what the platform and board should be in the YAML.
Thanks for tip, looks like chip is ESP32-D0WD-V3.

Looks like the board wasn’t the problem, but found ESP32-D0WD on Sonoff THR316 · Issue #2024 · esphome/feature-requests · GitHub which mentions that it needs to be plugged into AC. Plugging into AC seemed to solve the problem for me.
