@emil hi there, having the same challenge as all the other posters where new, small Wemo outlets are not registering with flic (using iOS).
I've used the homekit workaround stated in this thread, but this is somewhat limiting - it won't support toggling, so you have to use different flic actions to turn on/off. (and I only have 1 action free in the couple of places I want to use these). Any update on when the iOS update is due?
