You need to have a HomeKit Hub (AppleTV or HomePod) and ensure it is within range of the Eve sensor. Then you can access remotely including notifications. We have an eve on the front door and sends timely notifications from the AppleTV 4K in the lounge. Need to ensure it is set to not go to sleep
I have a 4th gen. AppleTV. Can this sensor's state be read remotely using my AppleTV?
Yes. We have AppleTV 4 working as homehub and I get notifications when I am away from home and I can check status
Elgato Eve Sensor
Yes. In the Home app you can set up to receive notifications if a door (in my case) is opened or closed. The notifications can be restricted to only certain times of day, and only happen (for instance) if you aren’t home. You do need a home hub for that, of course.
Of course it can, go into the Elgato Eve app or Apple Homekit and switch off the device.
