Update June 2021: people felt the methods in this post are too extreme. Fortunately, ASUS has since published a new support article on this topic, and I’ve heard that it works better. I haven’t tried it myself since I changed to eero (which works perfect with HomeKit) more than a year ago. Original post below.

I’ve had pretty good experiences with HomeKit with Philips Hue and Lutron Caseta. However, I noticed that standalone devices (ones that don’t have hubs) would often show “No Response” in HomeKit. This post shows some things that I learned trying to get all my devices to be reliable.
