Home automation not working (with new iPhone)

Hey there jorisparmentier,

Congrats on getting your new iPhone! Home automations are awesome, and we'd like to help however we can to get it working as intended. Let's rule out some possible causes by confirming the following details:

1. For your model, the latest version is iOS 16.0.2. You can verify this within Settings > General > About. Here's a link that'll show how to first back up, then Update your iPhone or iPad.
2. There have been several new updates lately, and with Home having things like your iPhone, home hub(iPad, Apple TV, etc.), there may be updates ready to install on all of your other devices. This link shows the latest update version numbers, along with the compatible models for each one: Apple security updates
3. While you also need to check for any new firmware updates for your Home Kit accessories, you'll need to reach out to the manufacturer of those accessories to confirm the steps to check if you're unsure of how to check for any yourself.
4. Have you already tried deleting one of the automations you set up, then adding it back to test for the same issue?

If the issues remain after checking the above details, the next step would be to get in touch with Apple Support to let them know what's been tried as they'll be in the best position to assist further with this: Get Support

Cheers!
