Yes, the IP address for https://data.envirodiy.org and also now https://monitormywatershed.org were changed on January 21 to 50.236.137.123.
This could change again in the future.

You can always find the IP address using a website such as https://ipinfo.info.

Can you really not just use the URL with your wifi XBee module?

Sara, thanks for your link to the bug on the XBee3 LTE-M RF Module. That is helpful to know that some of the issues folks have experienced were due to a known hardware bug. Do you know if the hardware fixed modules are available to purchase yet?

Also, regarding your concern about adding a manually soldered capacitor chain, your link describes why…[Read more]

I forgot to mention that YosemiTech also makes a multi-parameter sonde with an optional wiper. http://www.yosemitech.com/en/product-20.html

This is an approach to having a wiper on the DO probe, as none of the stand-alone DO probes have a wiper (unlike Turbidity, Chlorophyl and Blue-Green Algal stand-alone sensors, which have models with built-in…[Read more]

I highly recommend the YosemiTech DO sensors, which use optical sensing technology for long-term stability. https://www.yosemitech.com/en/product-cat-11.html

They use Modbus communication and can be user-calibrated. Here are their two main models (the Y505 is new and not on their website).

Y504 (standard model):

~$650 each (plus shipping plus…

@dkalo, The Mafly logger is now fully open source hardware!

We have released the Eagle .brd and .sch files for the latest Mayfly v0.5b board, at
https://github.com/EnviroDIY/EnviroDIY_Mayfly_Logger/tree/master/hardware

We also packaged things up nicely, including additional documentation from @shicks, into official releases,…[Read more]

@srgdamiano, thanks for making it really clear that the issues folks have been facing are primarily on the side of Digi’s LTE-M XBee3 hardware/software, and the work you’ve done with the ModularSensors code are all work-arounds to deal with the instability of Digi’s LTE-M XBee3 hardware/software when running on the Mayfly hardware.

I had failed…[Read more]

@srgdamiano, thanks talking to me on the phone Wednesday afternoon, explaining to me all your recent advances and successes.

All, I just answered that question on GitHub here: https://github.com/EnviroDIY/ModularSensors/issues/162#issuecomment-459879699

Here it is, also pasted below.

From what I understand, to get the Digi XBee3 LTE-M module…[Read more]

@srgdamiano, that is great news. Do your recent discoveries lead to a clear path for getting this to work with ModularSensors on the Mayfly?

Kevin and David,
Here’s a heads up that the after some testing, we pushed those development branches to the master branch of https://github.com/EnviroDIY/ModularSensors. The Maxbotix should work well now, and it should be much easier to find the right version of the code. We’ll give it an official release soon.

Kevin and David, thanks for posting these issues with the MaxSonar. David, thanks also for the photos!

I’ve also had funkiness with my Maxbotix deployments this summer when using the EnviroDIY ModularSensors library. For me it just seemed like it was repeating the last values.

David, thanks for showing everyone that quick fix and for helping me…[Read more]

@neilh, thanks for all of these tips. I’m just now diving back into all this, and actually need to make a lot of progress in the next 10 days.

I decided to still go with the Acculevel, because I needed the extra depth range.

Do you have any working Arduino code for the Acculevel? or even the nanolever. It would be a great place to start. My goal…[Read more]

Sara has done some great coding work with her SensorModbusMaster library, primarily in support our use of the high quality and inexpensive sensors from YosemiTech. We’ve developed a specific library for all YosemiTech sensors, which makes accessing all of the power functions quite easy: https://github.com/EnviroDIY/YosemitechModbus. All of this…[Read more]

MillerG, can you paste in the error codes you get with your first sketch?
Also, I reformatted your first sketch so that it would render better, but I’m slightly worried that I may have messed something up when I did it. Can you confirm that the first sketch is correctly rendered? Thanks!

DaveE, No problem! The circuitry is designed for 12V batteries and can handle up to 15V or so to accommodate for a fully charged lead-acid batter. We just didn’t want anyone to daisy-chain a pile of other batter types much beyond 12V, which is why we listed 12V.
We hope to be providing full documentation on the new v.5 Mayfly boards soon!

MillerG, thanks for posting your question here!

In the meanwhile, have you successfully run the “Simple File Example” sketch? It’s here: https://envirodiy.org/mayfly/software/simple-file/; and also on GitHub here: https://github.com/EnviroDIY/EnviroDIY_Mayfly_Logger/tree/master/examples.

Last, if you are using an SD card that is larger than…[Read more]
