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]
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
@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]
What version of Mayfly board do you have? And what brand of cellular board? There are a lot of combinations of hardware on EnviroDIY stations, and some are much more efficient than others. Also, do you have a spare Lipo battery that you can fully charge separately in your office and then put it into the station? If your logger is only wor…[Read more]
Hi thanks for responding. I’m sure our system is undersized for our location. Today was a pure sunny day, last week we installed an extension pole and cable so the solar is up plenty high to get direct sun. But today we got no readings sent via cellular.
Our battery is a LiPO 4400mAH 3.7V.
The solar panel is a 1W 6V
Open Circuit Voltage:…[Read more]
An update – I’ve found I2C bugs in some of the ST3100’s devices – that I couldn’t get a work around. It may be to do with the AVR I2C master. Some other engineers are using it with an STM32 / ARM system that they aren’t seeing the same problem https://github.com/neilh10/STC3100arduino/issues/1
From using the STC3100 -…[Read more]
