Shannon Hicks replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 11 months ago
The very bottom-left corner of the schematic for board v1.1 mentions the two charge rates, which you can control using solder jumper SJ15. Here’s the description of that jumper from the Jumper Settings page:
SJ15: Lipo battery charge rate: 500mA (default) or 1A. This jumper allows you to select the maximum charger output current of the onb…[Read more]

Hi,
What is the maximum recommended amps from a 6 volt solar panel to the V 1.1 board? Is this different for previous boards? There are two solar inputs–are these the same input but different connectors?
Thanks
neilh20 started the topic MMW lost readings in the forum Monitor My Watershed 11 months ago
I’m seeing a gap in data downloaded from the MMW database – about 5 days worth of lost readings.
It seems to be across all my devices. I spot checked a couple of other devices, and they also seem to be missing.
I noted it here but it hasn’t got a response https://github.com/ODM2/ODM2DataSharingPortal/issues/685
The lost data initially came up…[Read more]
neilh20 replied to the topic Coding to send data from a non-Mayfly logger in the forum Monitor My Watershed 11 months ago
@oakleynode something to note is that the MMW/ODM2 packet design with UUIDs make an extra heavy packet. The packet design is not optimally designed for wireless conditions, the thingspeak packets are much lighter. If your site is on the edge of the wireless range, which varies a lot of with weather conditions, its going to have more trouble with…[Read more]
neilh20 replied to the topic Monitoring power consumption in the forum Mayfly Data Logger 11 months ago
@shicks surely the issue isn’t how long it lasts – it will always run out of power at some point, or even worse batteries loose capacity, what was working decays – the issue is how to reliably recover when it has run out of available mA. ?
The reliable bit – as in all engineering – is to add a buffer for real world component variations and t…[Read more]

If your sample/transmission rate is set to 15 minutes and you were getting that poor of a battery life out of your stations, then they definitely aren’t going into sleep mode, so I’d suggest investigating the code that’s running on the Mayfly to learn more about its behavior.
James P replied to the topic Monitoring power consumption in the forum Mayfly Data Logger 11 months ago
I don’t believe any lights are on during the 15 minutes between data transfers. In the summer and fall lights would start blinking every 15 minutes, then stop for 15 minutes, etc. I’m not sure if there was something happening during the 15 minute break. Once I get the battery charged up with a powerbank i’ll check the dip switches.
Crazy, today…[Read more]

Thank you!
I will see if I can setup a route and test it out.

If you can create a POST request, you can get data to Monitor My Watershed. There’s information about the POST format here:

<p style=”font-weight: 400;”>Hi there,</p>
<p style=”font-weight: 400;”>I’m trying to figure out if it’s possible to route our data to your website. We have a couple water quality monitoring buoys that currently send data to ThingSpeak (using HTTP POST I believe) and I’m wondering if your Monitoring My Watershed data sharing portal is an option…[Read more]
