Citizen Hackers

Recently some citizens have been hacking a blood sugar tracking device called the Dexcom G4. They have created a phone app called NightScout to access it on their phones.
The advantages of this hack are that it will be infinitely more convenient for parents, and they won't have to stay within 20 feet of their child to check the blood sugar. They won't have to sit in the back of classes at school or follow their children around wherever they go. They can leave their children at home, for example, and they can still check up on them once in a while.
The disadvantages of this hack are that there would be serious trouble if the sender stopped broadcasting, or parents relied so much on it that they wouldn't wake up in the middle of the night to check on their children. If the sender stopped broadcasting and the parents were away, it would be catastrophic because they would know what was happening to their children. Then they would rush home, but it might be already too late.
In conclusion, I do not think NightScout is a great idea unless the parents still stay relatively close to their children.
