The Systeminfo Binding enables you to read system information through Sigar. The system information provided through this library can be extended with some additional important features. For example, reading system temperatures for your Raspberry Pi.
Earlier this week my first Raspberry Pi arrived by mail. What a great little device. I intend to use it to replace my Mac Mini. That Mac is currently running an openHAB server. Where the previous model B was said to be somewhat slow for larger openHAB installations, the hardware specs of this new Raspberry Pi 2 model B have increased. I expect it to be faster and fast enough for my purposes.
