Ahh, that could be it. When you connect with WebBLE and the meter viewer it shouldn't reset anything, but yes, if you re-upload code with the Web IDE then it will.
You can connect with the Web IDE and it won't reset anything - just don't click the 'upload' button or type
reset().If the power runs out then the data will be lost as well. It'd definitely be possible to save the data to a file in flash memory (maybe each day at midnight) so it wasn't lost, but that wasn't implemented in the code for the tutorial.
