I just purchased a Hub LR and 3 buttons. I've got the buttons added in HomeKit, controlling scenes that mostly trigger Phillips Hue bulbs.

Sometimes, the buttons work instantly. But more often, they lag, ranging from about 0.5 seconds to several seconds. The latency seems to be in communicating with the Hub, because when I push the button while watching the Flic app, the animation itself is delayed.

All the buttons are in rooms with good wifi coverage (my Philips Hue bulbs work instantly when I operate them from my phone). So I don't think that's the issue.

Is my hub defective? Is there something I can do to improve this latency?
