Why does the MCU show under ESPhome , did you use that same MCU with esphome before , you might need to do a clean up of old setting in HA , delete the integration and add wled again
By MCU I presume you mean the ESP32 running WLED, if so, I have no idea why it shows under esphome and I guess by your question, it is not supposed to.
I shall try to remove and reinstall the integration.
So wled is working correctly on its own ? can you ping the ip from your PC and from within HA terminal ?
it might not be possible to do anything remotely as I cant see your other HA settings
As per my first post, yes, wled is working perfectly via browser access on PC and mobile.
I am trying uninstalling ESPHOME and WLED and see if it helps. I’ve only got a couple of temperature/humidity sensors hooked up, so it’s an easy setup.
