does your router give you the MAC address of the device? You can look it up to see who manufactured it and then narrow down. This could be a device that has a web service running is all you are seeing right now.
You can always start looking at how to use WireShark to sniff the packets and learn more about what is coming and going from that system. WireShark can be a daunting tool but if you look at some videos or walk through you should be able to get a handle on how to make it reveal only the one devices network traffic
I have Wireshark, but haven’t really had a reason to learn it. I mostly just stare at the traffic rolling by the way they do on The Matrix. This is on the list to try.
Don’t need the router. If you’re on windows or linux, you just ping the ip then enter ‘arp -a <ip>’ it will show the MAC address for the IP from your machine’s arp cache.

It does not show up on the DHCP table, nor does it reflect pings.

How do you know it sent data? Any chance you have packet captures?
I had set my router to track IP Statistics. There were 9 packets sent and received to that IP.
