Now i'm in possession of one I thought i'd give a bit of feedback and initial impressions...
Initial setup was fairly straightforward (elected to set up via Chrome from a wired desktop, but you can use an app over bluetooth or via default wireless). Seemed to take a few retries to pick up my WAN connection (Virgin Media Superhub 3 in modem mode) but easy going after that to set up an initial SSID and password for the wireless and get things up and running. I'd already set up a Ubiquiti login to use and the 2FA worked from the off, although it wouldn't recognise the username (I had to use the email address as the user part of the login instead).
Setting up a guest SSID I did by following instructions i'd downloaded and was simple enough. There is a portal option you can enable but I didn't want to use that.
To minimise disruption i'd moved over SSIDs and passwords from my old setup. My wireless devices (a mix of Android phones, tablets and smart devices) mostly connected fine with no complications. The only oddities were...
- A Google Home Max that was previously on my main SSID flat refused to connect. Even hard-resetting and setting up from scratch it refused. Yet a Home Mini connected with no issues. Later when i'd set up a dedicated IoT VLAN and SSID (following a best practices guide off Ubiquiti's site) it connected first time.
- An Amazon Echo seemed to have connected but wasn't working. Again, this seemed fine when I set it up on my IoT SSID/VLAN.
I've still got a cloud cam and a Google Home Mini to shift over onto the IoT SSID, but moving a Chromecast and a smart plug over was pretty painless. Having followed the aforementioned guide then I can stream to the Home Max and the Chromecast fine from my main SSID even though its also a different VLAN.
Most the setup for the device I did via the web portal. Its a wee bit fiddly finding your way around at first and what lives where (some things you change in the dashboard views, a lot of the meaty stuff is in the slightly less fancy settings screens and the slightly confusing beta 'new settings' that lives a level below that). I did fiddle around with some things on the app but I prefer having a bigger screen real estate to work with and it made it easier to have documents up at the same time to work from.
One minor quirk from the portal was I couldn't find any way to reboot the thing remotely except for ssh'ing into it and issuing a reboot command that way. The option's either not there or well hidden.
For those interested in the WiFi capability of the Access Point, this has replaced an Asus AC68 and before/after tests of signal strength in a couple of locations shows the UDM is ever so slightly better (a couple of dBm better on the 5GHz channel).
For those interested in the aesthetics, its a lovely thing. Solidly built, lovely finish and well presented right down to the packaging. It wouldn't seem out of place if it had an Apple logo on it. Definitely a device that would score well on 'spousal acceptance factor' but for any network cables you might have hanging out of the back of it! Having the ports arranged vertically on the back of the device seems a slightly odd choice on an aesthetic level, although I suppose putting them horizontally or in a cluster might've been a challenge.
