Tasmota switches unavailable

Hi

Since the last update I connected my tasmota switches (sonoff, blitzwolf, gosund) via simulating wemo switches in the tasmota firmware. But since the last patch all switches are not available anymore. I added

wemo:
discovery: true

to my configuration.yaml but they were not found anymore.

What could be the problem? Because of problems with mqtt I don’t want to integrate them via mqtt. Are there any other options?
