Home automation

Hello 飞146,

Thank you for reaching out to Apple Support Communities.

You may need to recreate the automation in a way it doesn't interfere with your other Automations.

These steps may help:

Create an automation

If you set up a home hub, you can trigger an accessory or scene based on the time of day, your location, sensor detection, and more. Create an automation that triggers your "I'm Here" scene when someone in your family arrives home. Or have all of the lights in a room turn on when a motion sensor detects movement.

Create an automation based on an accessory's action

When an accessory turns on, off, or detects something, you can automate other accessories and scenes to react and perform actions.

1. In the Home app, tap or click the Add button , then select Add Automation. 
2. To start an automation when an accessory turns on or off, choose An Accessory is Controlled. Or choose A Sensor Detects Something.
3. Select the accessory that starts the automation, then tap or click Next.
4. Choose the action that triggers the automation, like if the accessory turns on or opens, then tap or click Next.
5. Select scenes and accessories that react to the action, then tap or click Next.
6. To adjust an accessory on iPhone or iPad, touch and hold it. On Mac, click the accessory.
7. Tap or click Done.
