We should absolutely have the option to select which device acts as the Hub and make it stick. I know exactly when a switch takes place. I start getting notifications for cameras/devices which shouldn’t be sending notifications at that time and lasts for a good 30 minutes until it catches up and settles with its duties. Why the random switch? Beats the heck out of me. The prior Hub was working just fine.
Last week I started getting some wonky behavior in my Home app. Just about every one of my devices went “No Response” and I had a huge banner at the top of the Home app asking me to set up my cameras using streaming only or streaming and recording. Mind you I had everything set up already. Turns out the acting Hub, an OG HomePod, was cutting in and out of Wi-Fi until I reset it. You would think this would’ve been the perfect time for the Hub to auto switch to something more reliable (I have 19 other Hubs on standby) but nope. Just stuck that one poor performing Hub even after I reset it. Had to go reset something else to force a switch.
What are the circumstances when you see the switch and the notifications?
Is it like when you get to work in the morning? Just randomly?
Little story, I was getting HomeHub disconnected and connected messages on my MBP a while back. I just ignored it. Finally after a month of I found that one of my HomePods would be the "Connected" device. This was fine when I was home with all my devices communicating directly. However when I left my house the Connected HomePod was incapable of being a HomeHub so it would fail and standby device would pick up the reigns.
I coincidentally fixed it because I noticed that HomePod wouldn't respond to Siri properly (Hey Siri set an alarm for 5am. I'm sorry something went wrong). Finally I reset it and then I noticed I stopped getting those disconnected connected messages.
On the cameras. Well I've given up on that. I have it set to notify me when if it records a clip, and only record a clip if it sees people, then set up a perimeter restricted to my porch. I still get notification from a car driving by 30 yards away.
