network device has joined the network
network device has joined the network

I have recently been receiving multiple "network device has joined the network at <time>" alerts at random times during the day. When I check the app for a list of network clients, I have 13 "network device" clients showing in the Offline Clients list. In the information for all of these clients, it says "Random MAC address detected."
Is this something I sould be concerned about? Could someone be attempting to get into my network? What is a "network device" client?

Wow, 46 devices on-line,,,, All those you show ARE HARD WIRED, Wireless devices have the 'wireless' icon before the '>'.
So, that to me indicates you have some switches maybe? Also, the MAC Addresses are 'fake', like Android and iOS devices do with Private Addressing.
You are left with a task that could take some time I guess...
- Go to EVERY one of the 46 devices or thier applications, and look at the Wired settings for it and look for a match of the IP Address OR the MAC Address.
- Turn ALL off, and one at a time turn them on. As each one is turned on, Edit the name...
Probably some might be camera's I guess, and not easy to reach or power off and on too I'd suspect.
In my case I had the problem with iOS devices, the Generic name, like iPad, Phone, Watch was given and the icon for the device did match... only problem I have, we had 2 of each in the home... and worse, Private Addressing was one, so they appeared as NEW DEVICES on every connect to the LAN when we came home with them,
If any do have Private Addressing on (I don't think camera's or wireless Tapo sockets) have that feature.
Still, all our Amazon devices provide a specific Amazon name to the router, but it doesn't indicate what it is, like an Echo Show or just and Echo. Even our Keurig Coffee machine showed as an Android name I recall.
Seems you have your work cutout for you.

Oh, in the Deco app, on the Client list, on the top right is a sort/display selection...
You can change it to be IP Address, like this:
We just had a Power Drop here with a Thunderstorm, and my list is this:
I am pretty sure I know what the 'amazon' one is, only device missing, and that would be the Amazon Prime TV stick. Since the TV wasn't on possible it didn't provide the name or has changed its IP Address.
It can take some 'work' getting the list named correctly. The Echo Show and Alexa Echo had similar names like the one I think is the TV stick.
