Hello faisaltheone,
Thank you for using Apple Support Communities. If you're experiencing issues with your accessories while using the Home app, we can share some helpful steps you can try. First, you want to make sure that all your connected devices are fully updated to the latest compatible software versions. Doing so can help resolve various issues. For HomePod, it appears that software version 16.2 is the latest version. Just in case, this resource can show you how to update your HomePod: Update HomePod - Apple Support
1.) Make sure that your device is updated to the latest version of iOS, iPadOS, or macOS.
2.) Open the Home app.
3.) Tap or click the More button
, then Home Settings
> Software Update.
4.) If there's a new update, select Update. If there isn't a new update, you can select HomePod to turn on automatic updates and get the latest software automatically when it's available. Software Update also tells you if your HomePod is already up to date, and shows you the installed HomePod software.
If every single linked device is fully updated, you can also try to remove the accessories and re-add them to the Home app. This step usually does help refresh things. If you've already attempted this step with no success, you're going to want to reach out to Apple Support for help. They might have to investigate this issue further with you. You can use the following link to contact them: Get Support
