I spent some of my weekend setting up OpenHab[1] on a rPi2 and a Z-Wave multi-sensor device[2] that gets me temperature, light level, humidy and movement. I have some more troubleshooting to do as the z-wave device worked great on USB power right next Pi (with a z-wave controller stick) but as soon as I put it on battery power on my front porch, its been flaky.
OpenHab was a pretty straightforward install. Its a java-based server app (built on jetty I believe) that has a system of bindings for different devices and a slightly quirky DSL for defining models and views/layouts (items and sitemaps) I don't know what else comparable is out there in this space, but it seems quite powerful and flexible. They have a database of devices that meant that even though the device I was hooking up wasn't one of the best-known brands, it was straightforward to set up - though maybe I got lucky. I've read a couple of places that z-wave devices can be flaky, but I've not done the troubleshooting yet to see if I'm getting data and its not displaying properly or what. I've got a wifi-controlled power outlet on the way which I'll hook up next. I got a big pack of arduino/rPI-compatible sensors but 0 docs came with it (not even labels on which is which) so I'm waiting on the vendor to deliver the promised docs. 1. http://www.openhab.org/ 2. http://www.iwasdot.com/configuring-a-aeon-labs-multi-sensor-with-openhab/ /Sam On Sun, Jan 24, 2016 at 8:53 PM, Karl Dubost <[email protected]> wrote: > > Le 20 janv. 2016 à 05:56, Sam Foster <[email protected]> a écrit : > > * per-room / non-central heating.
