Mac ID Confusion

C8 hub I configured for a friend at my house. Took it to him today. Hooked up ethernet cable, configured WIFI due to location issues. In his router I set up a reserved IP using the macid on the unit.

After re-booting, etc. Could not connect to hub. Searched router for macid. Couldn't find it. Went to remote admin and hub showed up. Under hub details it showed the macid correctly. But the IP was totally different. Went back into router and that IP showed a different macid. thus a different IP.

So apparently there are 2 different macid's in the hub. One for ethernet and one for WIFI. But nowhere does the WIFI one show up. And in the hub details it doesn't apparently show the correct one. It did show the wifi connection and the wifi name.

Yes. That is pretty standard for a device with more than one network interface.

When connected to WiFi, the hub doesn’t show its WiFi MAC address in the settings page?

I've never seen it any other way on a device that offeres both Wi-Fi and Ethernet connectivity. AFAIK each connection needs it's own MAC.

It shows the wrong macid. Nowhere in hub settings or info does it show the wifi macid.

I agree. But the hub only shows the one. No where does it show the other one.

Maybe the hub UI prioritizes showing the Ethernet MAC because it’s used for other things, like logging into the diagnostic tool?

Either way, if you reserve an IP address for a device’s Ethernet card, its WiFi card will always have a different MAC address and will be unaware of that DHCP reservation.

Look in the router’s settings page to find the hub’s IP address and MAC address while connected to WiFi so you can make a new DHCP reservation.

I agree with all you say, but the macid should show up somewhere on or in the hub setting. Without remote admin I could never have found it. Looking in the router would not help if I don’t know either the Mac or the ip.

This page finds hubs IPs on the local LAN https://findmyhub.hubitat.com/

It is made to be easy for people who are not up to speed on home networking. They would not even know what a MAC is or what to do with it even if it was provided.

Oops...I did miss this in your post above:

I wasn't aware that when connected via Wi-Fi the Details page still displays the Ethernet MAC. I've never actually had any of my hubs connected via Wi-Fi so hadn't run into this. I can see how that got you turned around a bit.

Yeah, I kinda guess my main gripe is that the MAC isn't listed anywhere. And when it's connected to WIFI the mac shown in Hub Details should be the WIFI mac.

Maybe something they should look at in further updates.

I would put that under the feature request tab. It's not a bad idea.

Thanks for putting the request in:
