What modem are you using with this setup?
TDDCR started the topic loggingInterval being ignored on v1.1 board. Logs every minute no matter what. in the forum Mayfly Data Logger 1 year, 9 months ago
We have some Mayfly stations set up already and I’m trying to launch a new one with the v1.1 board. Everything seems to be working fine except for the fact that it ignores whatever loggingInterval I put in and it just logs every minute. It writes to the SD card and sends the data online.
To test if there was some minor issue with my sketch, I went…[Read more]

Can you email me at mayfly@envirodiy.org, I have a few other questions about the software libraries and hardware combinations for your setup.
WFUWater replied to the topic Reading -9999 on all Sensors in the forum Mayfly Data Logger 1 year, 9 months ago
Unfortunately, we do not have any other boards. Would it be worth it to purchase a new one? Or is there more troubleshooting we could do with the current setup?
Shannon Hicks replied to the topic Reading -9999 on all Sensors in the forum Mayfly Data Logger 1 year, 9 months ago
Do you happen to have a spare Mayfly board, or any other Arduino-type board that you could run the sketch on?
WFUWater replied to the topic Reading -9999 on all Sensors in the forum Mayfly Data Logger 1 year, 9 months ago
Hi Shannon, thank you again. We were finally able to get a voltmeter and test the connection. There is voltage being applied to the sensors when the channel scanning sketch is running, but the program still says no sensor detected and to check the physical connection. We have tested both sensors. Could there be an issue with continuity?
Shannon Hicks replied to the topic Error Compiling for board EnviroDIY Mayfly 1284p in the forum Mayfly Data Logger 1 year, 9 months ago
The warnings you posted above seem to indicate that there’s a clash with the Sodaq DS3231 library. Did you by chance happen to install that library separately into your Arduino/libraries folder? ModularSensors already includes its own version of the DS3231 library which will conflict with the Sodaq library if they both exist on the same computer.

I have modified the sketch by replacing the UUID list in the original NoCellular sketch with my UUID list from Monitor My Watershed.
