Even though FlexVolt sensors have a pretty long battery life, roughly 10 hours depending on use, it would still be nice to be able to keep an eye on the battery level, right?  It would help to know when the sensor battery is low.  It would also be nice to know how much life the battery has left.

Battery monitoring required changes to the FlexVolt firmware – the programming in the sensor microprocessors.  I implemented and tested battery monitoring in the FlexVolt firmware today, and now it’s ready to go!  All sensors that ship out from now on will have the updated firmware so that they can transmit battery status to the apps.  Next I will update the apps to make battery status visible, including some sort of ‘time remaining’ status, and notifications when battery is getting low!
