⚠️ An error occurred. Improv Wi-Fi Serial not detected – Need Help

ESPHome

Hello everyone,

I’m facing an issue with my ESP32 board (8-channel relay, Aliexpress 8channel esp32

I keep getting the error: “:warning: An error occurred. Improv Wi-Fi Serial not detected.”
I’ve tried configuring the device through the ESPHome web interface, but it doesn’t seem to connect to my Wi-Fi. Do I need to change something in my router settings (FRITZ!Box 7520 QT)?

Additionally, could someone please guide me on how to connect from a USB TTL adapter to the board? What are the necessary connections?

I would appreciate any assistance, especially regarding possible config files or specific settings I should consider.

Thank you in advance!
