Hi @heather, Thanks for following up. All looks good to me!

Matt

I was curious whether opening Developer Tools (in Chrome) would show any insight to this problem. To my surprise, the Add Sensor button worked while I had DT open! One time I had to refresh the page while DT was open in order to get the Add Sensor dialog to display. Might be a workaround until the problem gets fixed.

This issue is fixed in the latest PIO dev version. Details can be found in the PIO issue thread.

I can recommend the Mayfly Hardware page, along with the Features and Jumper Settings links found there.

As far as reading and writing to the various pins in code, I’d suggest the Mayfly Software page, and particularly the LearnEnviroDIY link there, which is a series of detailed tutorials to get you started.

Good luck,

Matt

Thanks. I have a couple of protoshields now, as well as some 2×10 male headers, so I’ve got options to work with!

Interesting -thanks Neil. I may try that fuel gauge as well.

It would be interesting to see if the anomalies in sync with periods when the Mayfly’s battery voltage is peaking, i.e., during maximum solar input.

It sounds like you have the sensor on a separate circuit from the Mayfly. If that’s the case, should the grounds tied together between these two circuits? I’m not an electrical engineer, so I don’t…[Read more]

Thank you, Sara, for the additional tips for working around this PIO issue. I haven’t gotten a response yet on their github issues page, so need to post it on their community forum for others who are experiencing the same issue.

The online shop is awesome news for those of us building stations in quantity! Thank you Shannon and SWRC!

Thanks @armas. I have filed an issue with PlatformIO and am awaiting a response. -Matt

Update: This looks to me like a PIO issue. Reverting to earlier versions of PlatformIO IDE, it works; i.e., it downloads all ModularSensors’ dependencies as expected, and my project compiles successfully. This is using a ‘minimal’ platformio.ini file that looks like this:

[env:mayfly]
platform = atmelavr
board = mayfly
framework = arduino
lib_deps…

Yes, that works for sure; I had to do so last week just to get a couple of Mayfly loggers built and shipped out to the field. Now I’m revisiting the issue in order to get my dev environment back in order.

Hi Beth,

Thank you for sharing your experiences! I’ve tried those things too, and I’ve definitely had them work for me in the past. I thought I had gotten pretty good at smacking PIO around and getting it to behave, but today is apparently not that day…I’ve repeatedly restarted VSCode, created brand new projects, as well as cleaning out the…[Read more]

Thanks for sharing this good work, Neil. This does get technical, and I have a lot to learn, but your experiences will be helpful. For the short term, our team is primarily interested in knowing approximately what the limits are, for a given site, for a given set of sensors, whether the available solar power will keep our stations running for the…[Read more]

Interesting, thanks Jim. I’ve been wondering whether one of our problem stations has a charge controller chip that’s impeding its charging, so we’re preparing to swap out the Mayfly to troubleshoot.

It looks like this power sensor from Adafruit could work: https://www.adafruit.com/product/4226

This sensor, with accompanying library from Adafruit, returns milliamps, millivolts, and milliwatts via I2C, so seems promising.

This is new territory for me, so if anyone has insights or advice, I’m happy to hear it!
