Hey I know that we’re only in month three of 2026 and there are new products being introduced all the time. However, Aqara came out with a banger of a smart lock, the Aqara U400 that has now raised the bar.
It actually dethroned my previous favorite smart lock of all time, the Lockly Visage Zeno on one of my doors.
Why is the Aqara U400 so cool?
The Aqara 400 is the first available smart lock to support UWB (Ultra Wide-Band) here in the U.S. This technology enables you to unlock your door just by approaching it with your phone in your pocket or Apple Watch on your wrist. I’m not talking about waving your phone or watch in front of the lock (that’s Apple Home Key technology which this lock supports too), no I mean just having a compatible device on you.
If you followed that original video, you might have noticed that newer accessories (like Govee Matter lights) pair successfully but then inevitably throw a dreaded “No Response” error in the Apple Home app a few minutes later.
After diving deep into the latest UniFi OS updates and the strict networking requirements of the Matter protocol, I’ve completely overhauled my UniFi configuration. We are ditching the tedious port-specific firewall rules and fixing the multicast settings that are silently breaking your smart home.
This is important: While I initially visualized this setup around a UDM-Pro, UniFi’s form factors have diversified. But whether you have a cylindrical Dream Machine or Dream Router, or a rack-mount Dream Machine Pro, Pro Max, or next-gen Gateway, they all run the exact same UniFi OS, and this guide is the definitive update for all of them.
Here is the bulletproof way to configure your modern UniFi gateway for Apple Home, Home Assistant, Homey Pro, and Matter.
1. Ditch the Port Rules for “Stateful” Firewall Rules
In my original video, I had you create a Network Object for specific ports (80, 443, and 5353 for mDNS) and build rules around them. Delete those rules.
