It's on Ethernet, not wifi. Only one Ethernet port, on the back. The 00 21 b9 02 72 4c address does show on Iox finder, and when I login to that on the Portal, I get a completely different account. None of my devices are there and the devices (and scenes) that show on the Admin Console aren't mine. It's like someone else's system.
I'm brand new to Eisy, just got it to replace a ISY 994. The new Eisy R2 shows the mac address on a sticker on the bottom of the unit as 00 21 b9 02 72 4c. Iox finder shows the mac as 00 21 b9 f2 72 4c. Note that the 4th octet is different than what is shown on the Eisy label. f2 vs 02. What's up with that?
