Update:
AICO has been working on the software (both iOS and firmware) and it seems as though they take the reviews seriously! The firmware has been pleasantly updated so that in power save mode the smart egg is recognized after a number of days of being unused.
In addition they have added the ability to edit the buttons for existing remotes.
It doesn't seem as though they've added the ability to actually add buttons (maybe I haven't figured it out) and the order of the buttons is still odd, but it's good enough to get a 5 star review (I would do 4 stars, but most people on the App Store have much lower standards so...)
Just got my smart egg & it works great so far (have only added remotes via the preset list, added remotes via programming and creates some scenes). The only issue I have at the moment is with the thermometer as it indicates that the device is much cooler than it actually is, I adjusted the temperature and hopefully this will address the issue. I will be testing out the proximity feature soon.
My only gripes are (1) being unable to move/change the order of buttons, remotes or scenes. (2) being unable to add buttons to preset remotes. (3) And when creating scenes the time delay is much shorter than indicated (i.e. 1 second is more like a half second). Other than that it works as expected!
