I've been using node-red to tie together disparate 'home automation' systems. It makes it really easy to toy with glue logic, which then gets written up properly once I'm happy with the behaviour. eg, this is a 'flow' I use to turn my desk lamp off when I turn the room lights off - http://i.imgur.com/ZuVHhaN.png http://i.imgur.com/ZuVHhaN.png Of the inputs on the left-hand side, the top row takes a setter from an mqtt queue (via which I tie in with homekit/Siri), the middle row polls Hue's state for the room, and the bottom row listens for IR remote events. And then the blue element labelled 'Desk' is actually a switch on a web UI; it just happens to have a happy side-effect of marshalling the various inputs together. This 'flow' went from inception, to "I'm happy with it" in 5-10 minutes, and allows my Wemo switch (the output/actor on the right) to integrate with several products that the vendor have zero intention of ever supporting. It's easy enough that I only included the IR inputs as they took less than two minutes to add, making a very low barrier to "wouldn't it by nice if .." It's not code-free (I feel like I'm near-constantly writing functions to translate values between different systems), but it's an incredibly rapid way to build IoT-style automation.
