I like libre a lot, but, as other users will know, the factory calibration can be a bit iffy at times, and there's no hypo/hyper alerts.
However, a few weeks ago, xDrip+ was modified so that it will collect data from Ambrosia System's Blucon Nightrider transmitter.
The Blucon gets placed on top of the libre sensor, then it bluetooths readings every 5 minutes to xDrip+.
That means you can use xDrip+'s various features to calibrate against bg tests, set up hypo/hyper alerts, get predicted low warnings and a whole stack of other things.
I've been using it for a week now, been bg testing a lot more than usual to get a sense of whether I trust it's readings against blood. Have to say I'm pretty impressed with it so far. Being able to calibrate removes a lot of the uncertainties of libre and the alerts are great.
Blucon is a one-off cost of just over £100, runs off a replaceable watch battery, isn't waterproof so needs to be tagged onto the sensor with a plaster to allow removal for showers. The makers say it's warranted for a year but I suspect it'll last longer - it's just a circuit board and nfc reader so I'm not sure there's anything there to wear out. There's a £20 import tax in UK but there's a post somewhere on their facebook page about a way to reclaim that.
xDrip+ is free open source software which is covered by disclaimers saying it's a "use at own risk" gig, but it's used regularly by dexcommers and seems to be widely acknowledged as reliable.
All in all, it's a cheap and cheerful way of getting alerts with libre, so thought I'd mention it for anyone interested in getting alerts without going full dexcom or haven't the technical skills to build limiTTer etc. Not dissing dexcom in any way, I'm sure it's a wonderful product, but for various reasons I decided I didn't want to use it.
