Some features of MMW are still down due to some complex server issues.  They’re still working on it but haven’t given a specific date when everything might return to normal.

The database still has some issues with sparkline plots and a few other things.  The team is still working on it but don’t have an estimate on when things will be back to 100% functional again.

We just got the sensor and haven’t done any comparison tests alongside the Gen 1 sensor to see if there’s a difference, so I can’t comment yet on anything data-wise, we just know that there’s not a communication issue with the Mayfly now that we’ve adjusted the timing of the commands in our library.

We recently received a Gen 2 Hyrdos 21 CTD sensor from Meter Group and have confirmed that it works just fine with the Mayfly Data Logger, and using our Modular Sensors library, with just a very small adjustment made to the library.  We’re in the process of updating that now, so you should be good to order them and use them when they arrive.

Monitor My Watershed is still down and not showing stations on the main page when you click “Browse Sites”.  The data team is still working on repairing the site. But don’t worry, data is still being collected and all of it is available if you know the site code for the station you’re interested in.  For users that have their own sites or are following sites (My Sites), as a temporary fix, you can go to your My Sites (https://monitormywatershed.org/sites/) or Status (https://monitormywatershed.org/status/) pages to access the data.

You can also use Monitor My Watershed’s Time Series Analyst tool:  https://monitormywatershed.org/tsa/
You’ll be able to see all the stations on a map, and then click on it to take you to the usual TSA visualization for the station data.

Yes, it’s been down most of the day.  The MMW data team is working on it.

The new LTEbee adapter boards were finally delivered yesterday, I listed them in stock on the Shop page this morning.  Most of the people who have been looking to purchase them have already placed their orders.  But for anyone else interested in them, they are back in stock.  I also added the protoshields to the EnviroDIY shop, they were previously only available on Amazon.

If the Mayfly board still works when powered from a battery, then there’s a couple of possibilities of why the computer might not see it.  One is that the main power slide switch is defective, since that switch does 2 things – one pole is to provide power to the regulator that powers the whole board, the other pole is to provide power to the FTDI USB-to-UART chip on the Mayfly (FT232RL) that normally allows the computer to “speak” to the Mayfly board.  Sometimes one or both poles of the power switche can go bad if there’s a little bit of corrosion or dust inside the switch housing.  This can usually be remedied by rapidly sliding the power switch back and forth a few times.

The second (and probably more likely cause since you have 2 bad boards acting the same) is that a bad microUSB cable damaged one or more of the pins inside the little microUSB jack on the Mayfly.  Without all of the pins properly functioning, the computer won’t be able to communicate with the Mayfly.

There is a 6-pin header near the Mayfly’s SOLAR jack that can be used to program the board without using the onboard microUSB jack or the FTDI chip.  This is how I usually program all of the thousands of Mayfly boards I’ve used in the past few years because it is much easier than having Windows assign a new COM port for each new Mayfly that I connect to my computer.

I’d suggest ordering one of these FTDI programming boards: https://www.amazon.com/Adafruit-FTDI-Friend-Extras-ADA284/dp/B00NAY1VJ2

It comes with a little 6-pin coupler to allow you to plug it right into the FTDI jack on the Mayfly.  And because it uses the same FT232RL chip that’s on the Mayfly (v0.5b and earlier), you shouldn’t have to install any new software drivers on your computer.  Windows will, however, assign a new COM port to this new FTDI board, so you’ll have to look for that under your Arduino IDE’s Tools–>Port  list.

Be sure to plug it into the Mayfly in the direction shown in the attached photograph, otherwise you’ll be connecting the power and ground pins to the wrong pins and it won’t work.  This FTDI board uses a the older style miniUSB jack, which is larger than the microUSB jack on the Mayfly, so make sure you’ve got one of those cables instead of the one you used for connecting directly to the Mayfly.

The LTEbee adapters have been stuck in shipping transit for over 2 weeks, and then there were customs processing delays.  They been scheduled for delivery for the past few days but then get rescheduled.  Supposedly they’ll be delivered tomorrow (Monday) and I’ll list them as available in the EnviroDIY shop page in 5-packs as soon as they arrive.  I’ll also send single units to Amazon to restock the inventory there, but they typically take almost a month to restock, so ordering from the EnviroDIY shop page will be the quickest option for people who want 5 or more.

I’m still finalizing testing of a circuit for this, parts are on order but due to supply and shipping delays, I don’t have them yet.  Hopefully I’ll have something to report next week.
