HASS and Wemo Emulation mode on Sonoff Tasmota

I’ve recently flashed my iTead Sonoff S20 with the latest Tasmota firmware with the intention of using MQTT but noticed that the config has Wemo and HUE emulation. I’ve successfully been able to see the S20 in HASS under HUE emulation (it appears in lights) but when I choose Wemo emulation the device doesn’t show up even if I specify the ip in configuration.yaml.

Strange thing is when I did a discovery in the Alex app the S20 shows up for Alexa as a Wemo switch and can be controlled.

Any pointers to get the S20 to show up in HASS under emulated Wemo?
