@w3asa Did you look at this example: https://github.com/EnviroDIY/ModularSensors/tree/master/examples/DRWI_Mayfly1. I think it’s almost exactly what you want.

Sara Damiano replied to the topic Grove 4 pin terminal board in the forum Mayfly Data Logger 1 week, 5 days ago
To close the jumper on the Mayfly, you need a soldering iron. If you don’t have access to one of those, you might need to go back to the trinket.
You could also order a replacement pendant logger from Onset: https://www.onsetcomp.com/products/data-loggers/ua-003-64

Sara Damiano replied to the topic Secure Connection SSL help in the forum Mayfly Data Logger 2 weeks, 3 days ago
I don’t know if the Mayfly is powerful enough for any of the SSL libraries, but you shouldn’t need one. The SIM7080G itself can handle the layers of secure connection. The Mayfly should only need to tell it to use the secure connection. Look in the examples for secure connections in the TinyGSM library. Essentially all you need to do is call
TinyGs…

Sara Damiano replied to the topic Atlas Scientific Dissolved Oxygen Sensor Not Reading in the forum Environmental Sensors 3 weeks, 5 days ago
It’s been a long time since I played with the Atlas sensors, but from my notes, power cycling them can cause the whole logger to crash. If you want to power down Atlas sensors between readings, you need an I2C isolator. See the warning here: https://envirodiy.github.io/ModularSensors/group__atlas__group.html. The simple logging program should p…[Read more]

Sara Damiano replied to the topic Trouble locating information on new LTEBee in the forum Mayfly Data Logger 3 weeks, 6 days ago
The maximum transmission unit (MTU) for TCP is 1500 bytes. That’s why your transmissions over that size are failing. The commands TinyGSM uses for the SIM7080G are too low-level to break it up; you’ll need to do that yourself or submit a PR for TinyGSM. The XBee commands are higher level; it does the break-up for you.
My first guess for the…[Read more]

Sara Damiano replied to the topic Please Help! Meter CTD Gen2 being blocked by Yosemitech 511-a in the forum Environmental Sensors 1 month, 4 weeks ago
The ModularSensors library is running the SDI-12 sensors in “concurrent” mode and the modbus communication only happens when initiated by the logger. So the two sensors really should not be trying to talk to the logger at the same time. ModularSensors first asks each sensor to start taking a reading, then goes back and asks each one for its r…[Read more]

Sara Damiano replied to the topic SensorModbusMaster in the forum Miscellaneous 3 months, 2 weeks ago
I also responded on GitHub (https://github.com/EnviroDIY/SensorModbusMaster/issues/25), but the endian-ness of your sensor simulator is not compatible. You simulator seems to be sending CDAB mixed-endian. SensorModbusMaster only supports ABCD or DCBA.

Sara Damiano replied to the topic wofpy Timeout in the forum Monitor My Watershed 4 months, 2 weeks ago
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.

Sara Damiano replied to the topic 0.33.0 release testing in the forum Mayfly Data Logger 11 months, 2 weeks ago
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]

Sara Damiano replied to the topic Hydros CTD-10 Regularly Dropping Out (-9999) in the forum Environmental Sensors 1 year ago
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]

Sara Damiano replied to the topic Problems with libraries on the Mayfly Data Logger in the forum Mayfly Data Logger 1 year ago
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.

Sara Damiano replied to the topic Pin locations for Yosemitech Y510-B in the forum Mayfly Data Logger 1 year, 2 months ago
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
or0x0B
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

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.

Sara Damiano replied to the topic Connecting SIM7080 to New Thingspeak in the forum Mayfly Data Logger 1 year, 2 months ago
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.
