Hi Silver Mica,
Can you tell me what version of firmware you are using? Logging reliability has been a big focus of the beta development and has improved. If you’re not in the beta program already, I recommend joining it and updating your meter firmware. The latest release is 1470628829.
Another thing that’s improved in the latest firmware is adherence to the logging interval and feedback through the LED blink patterns. Check out moosh.im/wiki for more documentation.
The beta should be pushed to production next week (finally).
Hope this helps, best
PS. Thank you Ville for good answers!
