Thanks for the followup.

The problem I’m currently having is getting SD card logging to work reliably. I was happy to see that 10 minute intervals have been introduced in the latest beta firmware!

The problem I’m having is that logging just either seems to stop working or work unreliably. Is it normal for the meter to create a bunch of files with only one line each?

So far, I’ve just been trying to log the temperature using the internal sensor with a measurement interval of 1 minute.

How can I troubleshoot this? Is there anything I can do to make sure logging is working properly? It’s kind of hard to tell just by watching the LED.
