I ran across a few things some openHAB users might find relevant and interesting.
AdaFruit has developed and released a script to turn your RPi into a read-only mode. One of the cool features is you can use a jumper switch to boot into read/write mode for situations where you need to write to the SD card (e.g. system updates). This is probably not going to be reasonable for running your openHAB server itself, but if you have remote devices running on a RPi like sensors or weather stations this could make the devices behave much more like a microcontroller when it comes to power loss and the like.
MagPi Issue #63 (PDF download) has a brief article about using the Raspberry Pi and home automation. See pg. 62. Back issues can be downloaded from
The makers of MagPi have also released a new magazine called Hack Space. Like MagPi it is free to download and at least from the first issue it looks like there will be many articles of interest to home automation.
Plex Labs has released a new Plex Pass feature called Webhooks that allows users to set up HTTP calls from the Plex Mediaserver to configured URLs based on events on the server. This could be used for some alternative ways to interact with openHAB and it might provide features not yet available in the Plex Binding (I don’t use it so can’t comment).
