DaveG, since you inherited a monitoring station from a previous owner, you didn’t get the full training we give station owners when we teach a workshop and/or install a station for them. I would suggest looking through all of our EnviroDIY Monitoring Station Manual since we thoroughly document all of the information about station assembly, i…[Read more]

For the solar connecter, I colour the socket and the jack in an acrylic orange so that there is a visual match. The LiIon battery in a cooler blue. Of course have to be careful to only get the acrylic paint on the outside of the jack and not have leak inside. Its not perfect, but provides a little clue.

Suspect Mayfly1.1
The cable I was using also went bad and I’ve marked it as suspect – its a distinctive pink cable. I’ve inspected the Mayfly USB c on Mayfly1.1 with an Eye Loupe, and it is hard to inspect but nothing jumps out, seems OK.
I did have a USB current monitor in the testing before hand, and the current had gone up to 1.2A while…[Read more]

Are you saying you’ve got a bad cable or a bad Mayfly? Have you tried a different USB-C cable? The pins in USB-C connectors and cables are extremely small and are easy to fail. And when the pins in a cable’s connector get bent or damaged, we’ve seen them inflict damage on brand-new boards, so I’d suggest trying a new cable or two.

Matt, you are correct that it appears the solar panel was connected to the spare LipoBatt JST socket on the Mayfly, which causes the board to see those high levels during the day. The voltage regulator on the Mayfly can theoretically be damaged if you put more than 6.5v into the board via the LipoBatt jack, so they should definitely fix that as…[Read more]

These were just deployed 3 days ago and have been doing this from the beginning.

I am curious, did this just start or when you look back on battery voltage has it been doing this foe a while ? TomG2

We have 2 stations we’ve recently deployed which are reporting ~7.5 volts during the day and 4.2V at night (graphs attached).
I suspect that the solar cable was accidentally plugged into one of the LIPO BATT ports (with the battery is plugged into the other LIPO BATT port). They’ll get that corrected asap, but I want to ask @shicks: Would this…[Read more]
