Neil & Matt, thanks for that very good news from your testing!

I’m really glad to hear that everything seems to be working well again!!!

We think we found and fixed the major issue with slowness and 502/504 Gateway errors that have been increasing since this spring!

Please let us know if you see any slowdowns from the web-browser or gateway errors from devices trying to post data, just in case there’s yet another issue we didn’t notice.

Hey All, we found an issue that cropped up in late June on the database server for Monitor My Watershed. We’ll be doing a planned maintenance shutdown today at around 12:30 ET to fix the issue, and it will likely take about an hour. We’ll let you know when it is back up and running.

Matt, I’m glad you found the update helpful! I would be interested in connecting with you to more of your perspectives and long-term needs, if that’s of interest to you.

Thanks Robert, Cal, Jim and others for this thread, and to @shicks for providing all those updates on the Hologram situation.

I would like to add that our team overseeing the Monitor My Watershed portal has also noticed some issues on our end, which are separate from the Hologram issues, and we are working on improving MMW services.

Brian, you can use that DS18 temperature sensor on any of the digital pins (labeled on the Mayfly as: D4, D5, D6, D7, D10, D11), and because it’s OneWire, you can connect many DS18 sensors to a single pin using the I2C Hub (which generically connects multiple Grove connections in parallel). It just won’t work using I2C protocols.

Hey Matt and Neil, we’ve had a bunch of server-side issues in the last few days, so I’m guessing that’s more the problem than anything on your device. Part of the issue was a 5.5 hour internet outage to our servers caused by a Comcast fiber-optic line issue on March 31 in the afternoon. But we’ve had other issues that we’re trying to track…[Read more]

Hi Evan, I worked with Bobby Schulz to develop the https://github.com/EnviroDIY/Trigger library to un-inhibit an ISCO water sampler when turbidity was measured above a certain value. https://github.com/EnviroDIY/Trigger/tree/master/hardware/ISCO-Mayfly-Trigger

The Trigger library is quite generic, as it will send a pulse or change the polarity on…[Read more]

Hi @Evan, thanks for the heads up that Sparkling plots and Time Series Analyst are not connecting to the database. The data are safe, it’s just a connection issue for the visualization tools. You can follow our progress on the Hot Fix here: https://github.com/ODM2/ODM2DataSharingPortal/issues/473

Jim (@w3asa), I think the tutorial @fisherba mentioned back in Aug. 2018 is this one: https://envirodiy.github.io/LearnEnviroDIY/

We last updated it in April 2019 with our v0.2 release: https://github.com/EnviroDIY/LearnEnviroDIY/releases

So it is written for ModularSensors v0.21.2.

Otherwise, it is “complete” (but there is always room for…[Read more]

Following up on Beth’s comment on enclosure, the radio signal should get through the plastic case just fine, but the bigger issue is keeping distance between your antenna and any other metal, especially wires and battery but also including your solar panel. I’m always careful to place my antenna in the top of the box, keeping the wires, battery…[Read more]

Hmm. I wonder if it is somehow connected to our last release on Thu. Jan. 23. As Sara mentioned, we didn’t touch the code related to the HTTP post request, but at that time we did make some changes to our virtual machine host OS and our router.

Does it make a difference if you post to monitormywatershed.org, which is now our primary hostname,…[Read more]

@rachel.murray, that’s great to hear that you were able to get the YosemiTech Y4000 sonde working with our Modbus Mayfly Wing Shield and associated documentation. I developed all of that for a team at Winona State University in Minnesota, but I hadn’t been aware of anyone else trying to integrate the Y4000 with our EnviroDIY stack. So that’s…[Read more]

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…
