Soft (or virtual) FloatHub Available
Very cool, in looking at something on FloatHub's support site I just came across this:
FloatHub is making a software only version of their product available. Basically, you can use a small computer (including a Raspberry Pi it appears to run the FloatHub software and upload your monitoring data to FloatHub's servers. FloatHub has a free monitoring option, which is understandably somewhat limited, and makes this software available for free under MIT's open source license. All-in-all pretty cool if you're a little geeky.
