Will the A15 Apple TV 4K improve HomeKit hub camera stability?

Title: A15 Apple TV 4K Hub: Will it stabilize 6+ HKSV cameras vs 2021 A12 model?

Category: Apple TV > Apple TV 4K

Product: Apple TV 4K

Body:

Hi all,

I’m trying to decide if the new $300 Apple TV 4K is worth it as a HomeKit hub upgrade. Apple hasn’t published any performance data for "hub" functions.

My current setup:

• Hub: 2021 Apple TV 4K A2169 Wi-Fi model, tvOS 18.x

• Cameras: 3x Logitech Circle View, 2x Aqara G3, 1x Aqara G2H Pro. All HomeKit Secure Video

• Also running: 2x Wyze/Tapo via Scrypted

• Total: ∼40 HomeKit/Matter devices

The Problem:

When I open the Home app 6-camera grid, 4 of the 6 streams blink/disconnect every few seconds. I believe the A12 chip + 3GB RAM + Wi-Fi only is maxed out.

My Questions for Apple/Community:

1. Has anyone tested the new A15 Apple TV 4K with Ethernet on 6+ concurrent HKSV streams? Is it stable?

2. Does the A15 + 4GB RAM + Ethernet improve automation execution and Thread/Matter reliability vs the 2021 model?

3. Apple: Can you confirm if there is any increased hub capacity for cameras/devices on the new model? Logitech and Aqara are also waiting on specs for "enhanced streaming" on the new chip.

I don’t want to spend $300 on an assumption. Ethernet + more headroom should fix it, but we need data.

If you have this issue too, please click "Me Too".

Thank you.

If you have this same issue with 6+ HKSV cameras freezing on Apple TV hubs, please:

1. Reply below saying "I have this too"

2. Click "Helpful" on this reply with the video

Apple seems to track replies + "Helpful" clicks now instead of "Me Too". The more we get, the better chance they respond with hub specs.

Thank you!

apple are not here

these forums are user helping other users like yourself, it's sort of going to a physical apple store and asking other customers their advice

This is a user helping users with tech questions forum, we are not apple and apple do not read your posts here

personally I never experienced issues but then I only had 2 cams connected, not sure if apple ever setup to aim at homekit replacing bigger camera surveillance systems

Update with video proof - Day 3:

This is my 2021 Apple TV 4K A2169 Wi-Fi model trying to maintain 6 HKSV streams in the Home app grid.

As you can see, the tiles constantly freeze and reset every few seconds. Labels like "Rob's Garage" and "Camera Garag..." drop out too.

Setup:

3x Logitech Circle View, 2x Aqara G3, 1x Aqara G2H Pro. All HKSV

Plus 2x Wyze/Tapo via Scrypted

~40 HomeKit/Matter devices total

Question for Apple and the community:

Will the new A15 Apple TV 4K with Ethernet + 4GB RAM fix this instability? No reviewers have tested 6+ cameras yet.

Apple, can we please get official hub performance data before asking people to spend $300? Logitech and Aqara users are waiting on this too.

Thank you, I did that also, when I was not getting any answers, I started looking anywhere that looked like Apple might be either present or watching.

I appreciate your help!!
