Nice work Bryan! Now if only the pi zero W would become widely available for $10 the bottom line cost of the HM will drop down quite a bit...
I was working on the page this morning and all device registrations were sort of paused while I was making some changes. It should be up now, and your device will appear within an hour, of immediately if you reboot it and wait until the LCD displays the IP address.Edited to add: The HM doesn't show up on the device registration page now. The old RPi 3 one is still there but it just times out. Not sure why it doesn't show up with the zero but thought I should let you know.
