ive deleted my homekit automation and still have the same problem. My kids nursery lights always turn on if I pull up to the house in the arrive home automation. The test button doesn’t work either. I just don’t get it.
I guess you are using an iPhone for setting up automations via the Home app. What are you using as the Home hub - AppleTV, Homepod or iPad? Try restarting that device and check the automations on your iPhone to see if they have changed.
Another possible issue is that the iPhone is not using the same wifi network as the Home hub.
I just resolved some Automation problems by deleting the automation and creating a new one to replace it. This didn't work for you but others may find it useful.
Two other tips I found along the way:
Automation always turning on the wrong lights
