A couple more to add to your list:
Belkin WeMos - remember those old vacation timers with the big round dial and the little pins you had to set? WeMo's are the #IoT equivalent: http://www.belkin.com/us/Products/home-automation/c/wemo-home-automation/

SmartThings - I'm just getting started with SmartThings automation around my home, but so far I'm very impressed. My first project was automating the garage door. ST posted a blog about it here: http://blog.smartthings.com/how-to/how-to-openclose-your-garage-door/
