Lately I keep getting a system notification “New Devices Discovered” with a convenient link to “Check it out”. When I click the link it takes me to the Integrations page that lists all my integrations. I would expect to be taken to a list of the new devices so I can see what they are.
Here are screenshots of the notification and the result of clicking the “check it out” link.

If there are newly discovered devices, they will be at the top of the ‘Devices & Services’ page. However, your notification is from 5 hours ago and I’m guessing you already handled the new device (the notification has to be manually dismissed).
The notification happened in the middle of the night and I took those screen shots first thing in the morning. I didn’t knowingly do anything to “handle” any new devices.
I’ve gotten this same notification several times in the past month and I’d love to figure out what is going on. A list of the new devices would really help troubleshoot.
