I also have numerous Sonos zones & Nest for heating.
The Vera pretty much does what I want to do - lights on in the morning, lights off at night etc plus some voice announcements via Sonos.
I’m thinking of making the jump to SmartThings - not for any particular reason, but I like to play. Bonus would be fun with IFTTT & a nice app for my Apple Watch. I also am thinking of adding Hue in the future.
One of the most powerful things about Smartthings is its ability to integrate with third-party systems using a protocol called OAuth. Everything from IFT TT to harmony universal remote to visual dashboards like smarttiles to rules engines like smart rules, etc.
This currently works only for US accounts. It’s supposed to work for UK accounts, but it turned out multi region authorisation fails because the third parties are being directed to the US servers and they can’t find the UK account there. Smartthings without this integration just isn’t the same system. Support is very aware of the issue, it is being worked on, but I wouldn’t even start evaluating the system until this problem is fixed.
Much discussion in the following topic (this is a clickable link):
No timeframe has been given other than that they consider it a top priority and they’re working on it. It obviously hasn’t been easy to fix, as the problem was evident the first day of the launch. You will find comments from ST staff in the other thread, it’s probably best to continue the conversation there.
