On my GitHub, I have updated the app to also broadcast the mooshimeter battery voltage. Now I can have my phone beep or send a text message, etc when the meter battery gets low (using a Tasker sketch). I updated the Readme at the first post above. I think I am done with my updates. Famous last words :)

Also, on my GitHub, I updated my tool I have used to display what the mooshimeter app is broadcasting. https://github.com/DuaneOne/Broadcast_Intent_Tool/tree/master It is really just a simple receiver with a simple display of data received. So folks can see how it works, and use it without restriction. For those wanting to write their own receiver code, the tool will also send out a single value (pi), no units, in mooshimeter broadcast format for testing.
