I had an email from ST and now certain WeMo devices are now fully compatible with ST.
It says WeMo outlet, not mentioning the insight switch. However I did a new connect a thing, it found my insight, connected ok, and controls it, but doesn’t the standard switch.
They both work in the iOS WeMo app fine. I’ve reset the switch, connected it in WeMo again fine, but ST still doesn’t find it.
