IFTTT - Which device? No options available

I am trying to configure IFTTT to change the bulb color, BUT for some reason, I cannot see my devices listed in the IFTTT/eWeLink form. It says “No options available”, although, I have 3 devices defined and working fine from the eWeLink dashboard normally.
The devices are SONNOFF B05-BL Wi-Fi Smart LED Bulb.

SONOFF B05 is not supported yet, will be available in early June.

Thank you!

Is there a list of supported devices and bulbs?
I have subscribed for the advanced but cannot benifit from it with my bulbs.
