Heh, skimming over the comments it looks like no one has the same setup I settled on: Home Assistant as just a simple API. Home Assistant was pretty simple to install and connect to devices (I'm currently all Z-Wave), but I didn't really care for its built-in rules. But it provides a REST API to interact with everything connected to it, instead of having to fiddle with configuration files. So I have one system that makes sure the remote Home Assistant process is running, that provides a simplified API for everything else (mapping simple labels to the Home Assistant Z-Wave identifiers and handling the REST request for me), and a second one for actually controlling it with whatever rules I came up with. I've found it to be pretty stable overall.
