Long story short, had a hell of a time getting them to work (after installing the code, they would no longer connect to wifi). Anyway … with the following ESPHome YAML I managed to get them working, key points are comment out ‘captive portal’, set ‘baud_rate: 4800’ and ‘board: az-delivery-devkit-v4’ … here’s the whole YAML and all is working great. My other Keyes brand ESP32 boards did not require any of this futzing around.

These AZ-Delivery boards are cheap and seem to be one of the more dominant brands available on Amazon EU. Vs. I bought my Keyes ESP32 boards off the street in Hong Kong and couldn’t find an EU supplier.
