Hi, sonoff dual channel type CK-BL602-4SW-HS(139) missing support of CAST. This product appears on web interface (show as supported) on https://web.ewelink.cc but not when I try to insert them in a CAST. Please fix it!
I notice that I’ve to set a scene with only one CK-BL602-4SW-HS to work! It’s strange that individual devices are not seen in CAST, but they work within the scenes in CAST.
