The current deco app cannot show yet, but that function under development.

If you have PC, you can check your network BSSID cmd: netsh wlan show interface
BSSID will match your unit mac

How can you tell which devices are connected to which M5?

And what is the corresponding command if you're on a Mac? High Sierra?

Nevermind, found it .

Hold down Option key while clicking the Wifi menu.

What's the ETA on that functionality? The network with my M5's has only TP-Link home automation devices on it so finding out that info is not possible.

Well the BSSID didn't work, in fact it listed a mac that doesn't match any deco that I have. The command game me results of a BSSID:ac:84:c6:6b:e6:da and the physical deco right next to my computer is ac:84:c6:6b:e6:d8

I am also seeing this - my Deco BSSID MAC address reported from the network adapter is different from any device on my network (Deco or otherwise - I have them all logged with IP Scanner Pro.
It's very close to my Deco Mac though - last two digits are wrong. Does anyone know why this is?
