A lot of people want to know about the status with UI4. As a quick recap, since late 2008 Vera was shipping with a basic browser-based user interface called UI2 (user interface #2), which is what's featured in the wiki. UI2 is considered stable and functional, but not as pretty or intuitive as we'd like. In January, 2010 we came out with UI3. It was all based on Adobe Flash and you draw floor plans and positioned the devices around. Unfortunately it proved to be a big CPU hog because of the very complex Adobe Flash design. So, in March we went back to shipping Vera with UI2 because it had more universal appeal, while we began working on a simpler user interface, code named UI4. The new documentation for UI4 is available (with screen shots) at: http://docs2.mios.com/doc.php?language=1&manual=1&platform=0&page=dashboard
While software is always a 'work in progress', by early July we reached a point where UI4 was better all around than UI2. When Kwikset began shipping their Z-Wave locks in July, we began shipping new Vera's with UI4 because you needed the new UI4-based firmware to take advantage of the new Kwikset features. We also started a beta program where dozens of 'power users' who have used Vera for a long time could get UI4 and test the newest firmware versions before they go public. This has been GREAT. No matter how much we test there are always issues that are uncovered in the real world that don't show up in the lab.
At the moment then all new Vera users are on UI4, as are the beta testers. We have not yet publicly released UI4 for the existing Vera users, who are still mostly on UI2 and a few on UI3. A lot of people want to know when UI4 will be released to all the existing Vera users and what's the hold up. The reality is that although for new users UI4 is better than UI2 and the docs are better, it's a lot harder to smoothly migrate from UI2 to UI4 than just to start with UI4 in the first place. The back end data structure is totally different, so migrating from UI2 to UI4 requires a conversion process, kind of like opening a very old document in a new version of your word processor. Even the UI2 to UI4 migration goes smoothly 95% of the time, because there are many thousands of existing UI2 users, that 5% who did have migration problems would generate more support requests than we could handle and we wouldn't be able to keep up with the support tickets. That's why we're being EXTRA cautious about not moving everybody over to UI4 all at once until we're sure that the migration will work without a hitch for 99% of all users.
We're very close. Hopefully within 2 weeks we'll release a UI4 upgrade path for all the existing UI2 customers. We recently decided against making it an automatic update (meaning you get nagged to allow the update every time you load the UI) because we figure some people who are perfectly content with UI2 and already know it won't want to learn a totally new user experience. So there will be an announcement here soon with instructions on how to upgrade.
