I'm currently using OpenHAB with a couple Arduino sensor nodes. It works great. It does everything you've put in your required list and then some: rules engine, slick android app and browser interface, email / push notifications, data collection and charts. The only missing piece is the GUI for scene creation, but it's in the works. Also, great active community.
Here's some videos and tutorial of what I've got working:
I was in the same boat as you. All these "Home Automation" platforms take a lot of digging into to find out where their shortcomings are, what they're capable of. Although I did not do an exhaustive survey of everything out there, I did look at a few on your list, and ended up with OpenHAB.
