Cant send an invitation to Apple Home

Hello Martin_Kolembar,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are unable to invite someone to share control of the Home app and accessories. To help with this, see if this info helps:

"Before you upgrade

• Update your iPhone, iPad, Mac, Apple TV, HomePod, and Apple Watch to the latest software. Any device that is connected to an upgraded home and not running the latest software will lose access to the home until the device is updated. This includes people that you invite to control your home.
• A home hub, such as an Apple TV or HomePod, is required to share control of your home and to receive Home notifications on the new Home architecture. iPad is not supported as a home hub on the new Home architecture.

Upgrade in the Home app

Follow these steps to upgrade any homes you set up to the new Home architecture. All of the homes that you own are upgraded at the same time.

1. Open the Home app on your iPhone or iPad running the latest version of iOS or iPadOS, or Mac running the latest version of macOS.
2. Tap or click the More button .
3. Select Home Settings . If you own multiple homes, choose one, then select Home Settings . 
4. Select Software Update.
5. Tap or click Learn More under Home Upgrade Available, then follow the prompts to upgrade.
6. "

And that is from Upgrade to the new Home architecture - Apple Support. If you are still having this issue, please contact Apple directly: Get Support

Cheers!
