You only have 1 topic under homeassistant, so that is probably your wled.
My guess: you flashed tasmota-lite.bin, which does not support auto discovery. Upgrade to tasmota. bin and it will work.
The topic under homeassistant is not wled and I used the standard tasmota.bin. I found this guide which shows what I am seeing ( Setting up the Sonoff Tasmota MQTT Switch ), but I dont understand why autodiscovery does not work. I also do not know how to get the devices to publish to tasmota/discovery like the tasomota integration asks for.
