The WoFpy end-point should be usable.  Can you give an example URL that you’re trying?

Are you setting up a system to regularly poll Monitor My Watershed?  If this is something you plan do to automatically and frequently, please email help@monitormywatershed.org so we can talk directly with to make sure you’re using the most efficient endpoint possible.

Can you explain what issues you’re having?

Are you trying to use the library or to modify it?  The instructions you linked are for making changes to the library itself.

There’s an example of using an Arduino as an SDI-12 slave in the Arduino SDI-12 library.

The a-la-carte example isn’t usable as written any more. It got to be too big so I filled it up ugly pre-processor conditionals and snippet markers to use for continuous integration and documentation.

There are virtual functions all over the library, which definitely are eating up memory. I think almost the entire inheritance chain for sensors,…[Read more]

If the communication works sporadically, it’s more likely to be an electrical issue than a code issue.  Coding issues *usually* cause it to not work at all.

The -9999 is the library’s value for a failed reading.  When you get in in SDI-12, it most often means the sensor didn’t respond or the response was garbled.  Because the Mayfly’s voltage (a…[Read more]

The instructions for manual installation on the https://www.arduino.cc/en/Guide/Libraries are telling you how to find the right location to put the unzipped folder.  Once you have the right folder, you cut and past the files.  That’s it.

To update libraries, the easiest way is to delete everything in the library folder and re-download.

Can you c…[Read more]

Changing the address via the Yosemitech library is not hard.  I would strongly recommend you do that rather than mess with two adapters and two serial lines.  No matter what, I’m positive that the default addresses are not 0x04 or 0x0B as you have them coded.  Those are just my favorite addresses for them.

If you really want two separate co…[Read more]

There’s no enable pin broken out, so it must have automatic flow control.  That’s what you want.  This one, right:  https://www.amazon.com/ALMOCN-Adapter-Module-Converter-Indicator/dp/B09998FY4X?th=1

You said:

Currently the RS485 wires connected to the Y510-B into the mayfly are as follows: GND to GND, RXD to D11, TXD to D8, and VCC to sv5.

Sorry, I coded up the ThingSpeak publisher ages ago only to prove to myself that I could get an MQTT publisher working. I’ve never used it beyond that. I don’t have a paid account so after the trial period I was locked out and I’m not willing to do much testing on an account tied to my personal email.

Anyway, the code for ThingSpeak is in the…[Read more]

AltSoftSerial only works on pins 5 and 6. That’s why there’s no place in the code to declare the Tx and Rx pins. It’s strictly limited to those two.

<div dir=”auto”>Is there a reason you have the two sensors on separate RS485 adapters and power supplies? I’m fairly certain that the two sensors operate on the same supply…[Read more]

It’s been a while since I’ve used Atom.  Are you sure the program is compiling without errors and actually being uploaded?  If there are errors in the build, it won’t actually be uploaded.

Done.  Sorry for the delay.  Let me know if you have any issues adding a sensor.

The conductivity probe was already there.  I’m adding pH now.

I’m not sure if it’s possible – or if it is, it’s not going to be easy.  When you log in with your phone or your computer, you go through a series of browser pages where you submit form data with your credentials, etc.  I would guess that you’d have to manually figure out what the URL for each of those pages is and manually create each of the p…[Read more]

I haven’t looked into it much, but I would guess that module, and several other bee-shaped LoRaWAN modules would work just fine with the Mayfly.  There is *not* any direct support for any sort of radio communication right now in ModularSensors.  I would love to have support for it, but still a “someday” feature right now.  Right now most of our st…[Read more]

No, I don’t think I’ve seen that.

I’d put it in the power up, since it’s supposed to happen right away and setting the pin is nearly instant and won’t slow down other things powering up.

I added 10 extra ms of wake time in v2.1.3.  You can revert everything back to the original by adding a second argument of 0 to your send command functions.

Doh, yes, Shannon’s right!  I didn’t look closely enough before I deleted it, but there probably is a missing UUID!

Looking back, I replaced all the UUID’s with <<REMOVED>> for you so because you probably don’t want those to be public.  I can’t see or revert it to the original, but looking at it, your last measurement has just "":-9999} so it l…[Read more]

Hmm.  Does Hologram show any data being transferred?

Monitor My Watershed is known to sometimes drop or not respond for no apparent reason.  But usually if one station is working all the time and another isn’t it’s either the UUID and tokens or the internet connection.  When you’re looking at MonitorMW, are you seeing anything at all?  The num…[Read more]
