"Master Hub (Bridge)" discovered but cannot figure out what this device is

Good morning!

I’ve had a device appearing forever called “Master Hub (Bridge)” with Homekit and I’m just lost as ever. I have all my TVs and my garage door controller added via Homekit. I can’t figure out what this device is. Nothing in the logs matches the device name to try and sort it out.

Any thoughts on figuring out what is being detected so I can add it?
