Reply To: Mayfly unit stop sending data to the online site

For data you have on the SD card, you can upload it so that it appears online following these instructions: https://wikiwatershed.org/wp-content/uploads/monitor-my-watershed-quick-guide-uploading-data.pdf.  NOTE: The instructions mention that there’s a file size limitation.  That limitation no longer exists.

Sadly, though, if your data isn’t on the SD card and wasn’t posted online, there is no way to recover it. There is no other place the data would be stored.  The SD card is the only local data storage on the Mayfly.  If something happened that made the whole station go down and stop writing to the SD card, there’s nowhere to recover any data from.

For me to help fix the station so it will record and publish data again, I’ll need to know more about its current condition.  Are you sure the battery is good? Have you tried turning the station back on to watch what it does on your desktop? Do the lights blink when you turn it on? Which lights? Can you connect it to a computer and share the serial monitor output?
