How do i fix slow HomeKit connection?

The issue is neither a third party hub nor your wifi connection - the issue is with Apple HomeKit. There are countless threads about this issue. Once you have multiple apple devices that are Apple HomeKit Bridge enabled like Apple TV, HomePods, iPads etc....the HomeKit network starts to degenerate and it will take forever for HomeKit to connect to devices and execute commands and scenes. I assume that you have more than HomeKit Bridge enabled devices. Once you do that and the more of them you have, the longer it takes for HomeKit to connect to devices and execute commands including scenes. Its almost like the network of HomeKit Hub enabled devices is arguing which one is to send the request to a HomeKit enabled device. Resetting everything and restarting or deleting and start from scratch will not fix the issue. On top of that Apple's HomeKit ecosystem relies entirely on third party devices like light bulbs, switches and smart plugs as Apple does not make their own. So you are relying on 3rd party manufacturers to play nice with HomeKit and that does not always work.

I don't agree - setting up the homekit from the scratch solves your problem for a week or two and then it starts to get slower and slower again. I am not talking about 1-2 seconds, I am talking about 30 seconds or more. This can also cause problems if you have shortcuts that wait for other devices as there will be time-outs and other errors.

I have 3 Homepod-minis, 2 Homepods, 2 ATV, 2 iPads and 2 iPhones - deactivating the devices that you can deactivate doesn't solve the problem either. Homekit started to get slow after two weeks after installation of ATV 4K last fall - in the meantime I have reinstalled everything from the scratch twice and after two weeks the system is slow like the first time I observed that problem. I also suspect there is a problem in Homekit itself.

Hello elangsru,

We understand that you have some concerns regarding the responsiveness of the Home app. We're happy to offer some direction.

The first step we recommend is restarting your device to see if the behavior improves at all. If you are seeing this behavior in other apps, your battery life or available storage may also be a potential cause. See iPhone Battery and Performance for additional information on how battery life can impact performance.

Another step you may consider is removing the Home app from your device and reinstalling it, per Delete built-in Apple apps from the Home Screen on your iOS 14 or later or iPadOS device or Apple Watch. Please note that this step may require you to reconfigure your Home app and all accessories and automations or scenes you've set up.

If you still see the described behavior, use the link at the bottom of either article or in the top right of this page to contact our support to investigate further.

Cheers!

Welcome back elangsru,

From the details provided, it appears this concern may be isolated to the hub you mentioned. It may become necessary to consult the manufacturer of that device or software for advanced troubleshooting.

If the proposed steps don't correct the behavior you're reporting, use Apple - Support to connect with our teams to investigate further.

Thanks!

You are correct. I did it twice: completely erased my home, deleted the home app, reset all HomePods and smart devices, downloaded the home app and set up all smart accessories from scratch. Worked for a few days then it started slowing down again at times to a point it’s unusable. But hey Siri will now speak to you in a gender neutral voice so all good right?

Na did that worked only for a few days.
