[quote='870053022, DTS Engineer, /thread/810454?answerId=870053022#870053022'] please post to the thread again to get my attention [/quote] Hi @DTS Engineer, just a friendly bump on this issue.

Decided to start from scratch to see if it would resolve the issue. I removed all of my 100+ devices, deleted scenes/automation, and deleted the Home. I rebooted all devices (including network) and created a new home. I started off with adding Hue device and when I later launched the Home app I got the "Home hub is unresponsive pop up". I did set everything back up again and will continue to monitor but so far the issue unfortunately still persists.

[quote='870053022, DTS Engineer, /thread/810454?answerId=870053022#870053022'] At a minimum, that means a sysdiagnose from both the device showing the issue and the home hub [/quote] Updated the ticket (FB21366014) with sysdiagnose from iPhone and Apple TV

[quote='870053022, DTS Engineer, /thread/810454?answerId=870053022#870053022'] K-MTG- what router are you using and, in particular, is it Ubiquiti hardware as well? [/quote] Yup, I'm using a UDM Pro. I have their switches and APs as well. I'm currently offsite from the home having issues so I won't be able to get the sysdiagnose from the Apple TV until next week. Currently, I just provided the sysdiagnose from my iPhone.

Yup, the bug ticket is FB21366014. Btw...I also see a few posts on reddit (r/HomeKit) regarding this issue.
