So, just installed the WiFi module two days ago, and the short answer is "not really." I have an AI Prime on my QT tank, so very familiar with myAI (and Mobius at least for MP10s).
The physical install of the WiFi module on my Photon 24 v2 was straight forward and took about twenty minutes. You do need to melt some red wax holding the cables with a hair dryers, and be careful to realign the optics if they get gently knocked out of place, but really pretty easy and painless. When it came to connecting it to the app, the process unfortunately was a bit more frustrating. I'd say it took roughly 15-20 tries, including resetting the wifi board, uninstalling/reinstalling the app when it kept crashing and wouldn't open again, adding/removing the light in the app, etc. Maybe I just got unlucky and YMMV, but definitely sub-optimal. That said, I was able to finally get it connected, which is obviously a huge plus.
Having now spent some time with Nexus app, I can safely say it's a step up from the remote, but still a very fair cry from myAI. Basically, you go in and set a "Sunrise" and Sunset" time and then for each of the six channels separately add/remove individual adjustment points based on desire ramp up, max intensity, and ramp down, with the only default option for moonlight being cool blue. I actually prefer the violet for a moonlight, and since you can't add adjustment points outside of the sunrise/sunset times which I found a little annoying as I played with settings, I set both to 12pm effectively eliminating it and then adjusted everything else I wanted from there. This seems to be an easy enough work around, but still a little awkward. You also have to click through the entire scheduling setup process from the beginning if you want to make any changes.
Other things in myAI not in Nexus include, ability to see/set all six channels for a single adjustment point or time at once, ability to scale the entire intensity of the schedule up/or down (two finger drag in myAI), ability to save/switch between different stored presets, ability to test spectrum settings across your scheduled day without doing a separate manual override, ability to see the spectrum chart output for a given setting (to the extent accurate in myAI), no automated acclimation setting, etc.
In short, it's just very basic but serviceable. I don't want this review to come off too negative, as I do very much like the light, particularly at it's price point. But people shouldn't go into this thinking that the app, at least currently, is going to be anywhere near as refined as myAI or Mobius. Again, not surprising given the likely difference in development cost and time. All in all, I'd say this is a survivable initial app, but could greatly benefit from additional upgrades in terms of layout, design, functionality and error handling, which I very much hope are in the works and part of the product's evolution.
