If anyone here is still interested, I tried the Utilitech GB-00Z-1 Glass Break Detector with the Almond+ and it at least appeared to work for me. It paired right away. I chose "other" vs. flood or smoke as the alarm type during the pairing process and it shows up as a generic alarm sensor. The test button on the detector does not trigger an alarm on the Almond (it doesn't on the SmartThings Hub either) and so I used YouTube glass breaking audio samples to test rule triggers. It wasn't a scientific, reliable or repeatable test, but it appears to operate similarly with the SmartThings Hub. Battery level showed 94% which doesn't appear unreasonable.
