Interesting – does the Mooshimeter show similar variability when reading while connected to the app, or only when logging with a 10s interval?
If the meter is working fine while connected but displaying slight variance in logging applications, my hunch is that the settling time (time between meter waking up and time between logging a sample) is insufficient. This would be a firmware issue. I’m changing the way settling time is handled to address some other concerns users have brought up with logging in the forum, so I will factor this feedback in as well. Expect a longer settling time in the next beta release.
