I finally dug into this.  As I commented on GitHub, I think this loss must be related to a server update or hotfix.  The server did get the data, so it might be recoverable. I doubt it’s related to the older issue.

Hi Shannon. So I just received a few more panels. The stereo jack cables are going in relatively easily with these. I think I received some damaged hardware, causing the stereo jack cable to be very difficult to get plugged in. And causing a bad connection to the logger.

@paulwilson Yes, the payment page for Monitor My Watershed subscriptions will begin accepting payments on 01 January 2024. Thank you for supporting Monitor My Watershed!

I’m very much a fan of ModularSensors and the discussion board as a place to be real with technical issues.   I do so appreciate the unique place EnviroDIY has been curated to be, to try some remote wireless terrestrial monitoring. Its the nitty gritty of environmental monitoring and the engineering it takes.   Its tough to find out what these ser…[Read more]

Am I correct to assume that the payment page will open after the first? I tried to pay for 2024 now and got the message “This product is currently out of stock and unavailable.”.  Thanks.

I have a multimeter that can measure amperage. I’m not sure how to get it inline with the circuit though without putting together a couple wires with the proper jst connectors…I’m not an expert in this and don’t want to short the board.
Any suggestions on where on the board or how to test?
Thanks!

I haven’t had much luck getting to 0.5mA with mega1284, it was with the Mayfly 0.5b- https://www.envirodiy.org/topic/testing-power-consumption/#post-15252   My notes on measurements is that it was between 2-2.5mA.  I did get well beneath 0.5mA   on another project with mega2560, but that was a lot of hardwork, and also ended up with a higher valu…[Read more]

You could also try putting an ammeter in line with the main battery (with no solar or USB connected) to monitor the current of the board during use.  When it’s sleeping, you should see a current of about 0.6mA  for your configuration.  If you measure a sleeping current above 1mA, then something is probably wrong, either the board isn’t properly sl…[Read more]

Thanks for all your help. I believe that the bigger solar panel with >1A peak current, a 1A charging current to the board (jump SJ15), and a freshly charged battery should remedy the winter issues.

Regarding consumption, I took one unit home, mostly charged a LiPo 3300mAh battery, here is what I found (no external sensor connected, transmitted…[Read more]

@jp – the charger relationship doesn’t quite work that way. The 5V 2.0A is typically the stated maximum the charger can supply – however for the battery charger circuit there are limitations. I use a USB Meter to determine what is actually going on.

The Mayfly 1.x charger circuit is to 0.5A as default  but can be changed to 1.0A. I always change…[Read more]

Thanks Shannon. I was actually talking about the stereo jack. See attached image.

Since we transitioned to the new panels it has been very difficult to get the stereo jack from the panel plugged into that adapter cable. Any recommendations on that are welcome.

I’ve had a 5v 2.0A usb charger plugged in for 3.5 hrs. The yellow charging light is still on. I think it should take ~2.5 hours to fully charge a 4400mAh battery with a 2.0A charger, so it should be done.

Does someone know if the board is getting any feedback from the battery on whether it’s accepting a charge or not? If there is not feedback…[Read more]

Thank you for the quick response, we are looking forward to the new modbus adater.  Meanwhile, we made some quick changes to  existing wingboards to power the Y-551A from the 12v available on the V1.1 rev B, with good results.   One station is back to normal and the other should be as soon as the updated wingboard is installed.  Thanks!

Thanks! So the yellow light was on because solar was charging, that’s good news. I assume that light is powered by the sun and not the battery.

Our next step will be to replace the battery if the full overnight charge doesn’t work. I’ll set those two DIP switches to off after I try to fully charge the battery.

They’re spring-loaded quick connect jacks.  The wires go in the round holes not the rectangular ones.  If you tug on them and they don’t come loose, then they should be connected properly.  If they pop out, then you’ve just got to insert them further.  I usually use my fingers, but you could also use something like needle-nose pliers to push one…[Read more]

A description of the operation of the LEDs on the Mayfly board can be found here:  https://www.envirodiy.org/mayfly/hardware/details-and-specs/

For the one you asked about, it’s under part C:

C- Power LEDs and DIP switches:  LEDs indicate board power (green) and USB power (orange).  Useful for easily seeing if the board is on and if USB power is…[Read more]

Yesterday I attached a powerbank to the usb-c port for a little over two hours. Two yellow lights were on, one near the usb-c port and one lower down. I also installed a 10w solar panel. When I detached the powerbank, the yellow light near the usb-c port turned off but the other one stayed on. The station held voltage for two hours after that,…[Read more]

Any tricks on getting the new solar panel jacks plugged into the 2-pin adapter cable? They are really difficult to get in and I’m wondering if something was damaged while it was being plugged in due to the effort of getting the plug seated.

The Yosemitech Y-511A needs 12v to operate, so it won’t be happy if you modify the Mayfly jumper to set the 12v output to 9v.  I’m not familiar with the operation of the modbus wing you’re using so I can’t comment on its operation, but we have a new modbus adapter board with it’s own beefy 12v-boost Grove adapter board that will be available in…[Read more]

Thank you very much for the answer. No, the rain gauge was deployed as it came out of the box. The sensor was leveled during installation, but the pole was not re-leveled since then and it was there for two or three years. I was asking Meter for help and asked them directly if there is some posibility to adjust it and they said “no” so I am bit…[Read more]
