As for a release? Please read the latest Kickstarter/Blog update.
It's progressing quite quickly internally though and we have a fully working, albeit somewhat limited UI now.
I don't have an exact release date, but we're working as quickly as we can.
Please keep in mind that we need to offer support for a huge range of difference combinations of scenarios based on the sensor types we support, which is fairly complex on its own.
We also have to figure out sensible UI's for things like timers etc. but most of that is working by now.
I'm afraid that's all I can share for now, but once it's close to release, I'll do a blog post with a lot more details, as well as a Wiki entry explaining how to use it.
