@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]

@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.

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:

@shicks I agree it would be good to see the software. For my systems I look to have it last 14days before it reaches 3.8V and it is a difficult target unless its being tested for and the time taken on the radio is also characterized.

I see the issue is how to keep the sensor readings delivered reliably while there is enough power, and then when…[Read more]

@@w3asa – Thanks for sharing your thoughts on our subscription plan pricing structure. We arrived at this pricing structure after exploring all the options for most equitably distributing costs across the diverse community of users and organizations. We hope users appreciate the extra value that Monitor My Watershed provides in comparison to other…[Read more]

We certainly understand how valuable it is for Monitor My Watershed users to share their data on their own websites. While there isn’t a direct way to share Monitor My Watershed webpages, there are several ways to automate the data download process for reprocessing and posting your data in a separate service. First, you can retrieve a csv file of…[Read more]

James, your station seems to be using power at a rate much higher than a usual CTD station.  Our Mayfly v1.1 boards with EnviroDIY sim7080 LTE board and a CTD sensor will see a decrease in the battery voltage overnight of 0.045v during a 12 hour period with absolutely no sunlight, and transmitting the data to the portal every 5 minutes.  Your s…[Read more]

Is there any chance to provide a finer price structure?  Perhaps a fixed amount (~$5) per station with some discount for larger quantities.  For example going from 3 to 4 stations would cost about four times as much per station!  Also I noticed that there is a price break for a full year subscription for the small plan but none for the medium an…[Read more]

(previous post deleted and restated)    @jp – interesting data. It very much looks like up to early October the solar was delivering enough power for the system.

Then with the seasons solar changing, the solar panel aspect is not delivering the power needed

What I would recommend is a) need to charge up the internal LiIon 4.4Ahr battery

1. …

@jp – interesting data. It very much looks like its the solar panel aspect that is not delivering the power with the seasons changing, and some loss of solar.  a) So anything you can do to help out a better solar aspect  – less shade would help, and  solar panels are best set at an optimal 120 from horizontal for that location (h…[Read more]

Thanks for the data, Our site has much more exposure to sun than in a redwood forest, and  is doing something similar:

Note the times on the website are accurate but when you look at the data the times are not accurate — sun isn’t up at 5am. I wonder why the clock reset..
The last…[Read more]

Hi @jp – I only install 2.5W or for a shady location I upgrade to 10W.   Can you share the site that is publishing on, and can see how fast the power went down.

The non recharge batteries could work – but you need to do a lot more power calculations to understand how long they will work.  4 batteries (4*1.6V =6V) will work for a boost plugged in…[Read more]

I think it’s reasonable to pay for the hosting of these data, and the price structure allows small organizations to afford a few loggers.  Are you planning to allow or make it easier for subscribers to use their data in real time on their website (via either iframe or another method?).   This would allow us to more easily fundraise (for ex…[Read more]
