My Apple TV is my main hub. However, if I use Siri via my HomePod, I can't use any scenes that are in my HomeKit. This kinda sucks because the usecase that I bought the HomePod for, is to activate scenes.
I know that you can't "guide" Apple HomeKit to decide what device is your active hub, and what is your standby hub. However, by magic this is correct (Apple TV is active, Homepod is stand-by)
According to this article, it should not matter, but it does in my case... https://www.homekithelper.net/devices/hubs
Next I would try removing the AppleTV from the Home. Force the HomePod to be the hub and see if scenes work.
If that doesn’t work, I’d try completely starting your Home over, with the first device you connect being the HomePod and the second being the AppleTV. I realize that’s not ideal but you’re having abnormal behavior here. I have an AppleTV, HomePod, and HomePod Mini on a network with multiple smart devices and everything works fine.
Yeah, first going to see if my network config is good before going to the extremes of deleting the home. We have multiple scenes (+10). Recreating them is possible, but not preferred.
Makes sense. I just spent 5 days reconstructing my network due to a variety of inefficiencies. Happy to say it worked out on the end, but it was hell during.
