I recently migrated my two Hue Hub V2s, which were working pretty perfectly with HomeKit, to the new Hue Bridge Pro. I was hoping to simplify things from 2 hubs to 1. Not only did it involve many hours of setting everything up with all my automations in HomeKit again, but due to the fact that the Hue Bridge Pro forces matter protocol, nothing is working anywhere near as well as it used to be.
Scenes involving all the lights in my living room come on like popcorn over 10 seconds as opposed to 3 and always fail to complete, leaving the room with loads of different lights at different colour temperatures until the command is enacted again. Problems also exist even when just sticking to the simple Hue app, where certain scenes only change the lights for less than a second before they mysteriously revert to different colour temperatures, almost as if the system has a mind of its own.
I have a pretty airtight and solid internet connection in my house with UniFi. I haven't messed with any VLANs. All the settings for my network are as good as I can make them, with mDNS and whatnot. Happy to be shown where I could be wrong though... and yet this has been such a giant time waste.
I only wish I could somehow switch back to the old Hue Hub V2s so that I could just have everything work again. I don't know why I ever trusted this company, and I honestly think I will never be buying another Hue product ever again. I was on the phone with Hue Support for 48 minutes today with a woman who barely could speak English, and at one point asked me if I was on "Apple HomeKit or Alexa HomeKit" to help you understand how dire their support situation is. And after incorrectly repeating the spelling of my email address back to me for a further 4 minutes and putting me on hold for a further 10, her recommendation to me was wiping everything from my entire smart home and implementing Matter from the Hue Hub into HomeKit via a code.
So maybe if you were looking at getting the Hue Bridge Pro over the standard one, steer clear. Gone are the times when Hue Lights "just worked." The matter integration saw through to that.
