What happened to the post from a while ago, you said you were working on new MFi device range?
Also, can Yeelight not work on software authentication? I love my Yeelight bulbs and light it would be such a shame for it never to work with HomeKit. Your Alexa integration is already great. I don’t really like Apple’s local-only implementation that is a bit annoying but it would be nice to use the Home app.
