Never mind!  “download Sensor data”  seems to be working now.

“download Sensor data” was very slow to respond (several hours) now it doesn’t seem to work at all.  Does anyone know the status of this? Is there another portal to download station data?

I thought it wasn’t working on my Mac using Chrome but realized the download is slow.  Took about 5 minutes to download a 6 MB file but no problems with the file.

Since the data server still appears to be down is ther any way to download data via TSI which does seem to be working?

here is attachment

I note the data server is still down.  My Mac response is attached.  “download.html” doesent show in my download file which I assume is because file doesn’t exist.  Any update on the status of a fix?

Thanks

I tried to sign in today to pay for the GMI medium plan at $49/mo.  The store doesn’t recognize any of my credentials.  Do I need a different account?

Is there any chance to provide a finer price structure?  Perhaps a fixed amount (~$5) per station with some discount for larger quantities.  For example going from 3 to 4 stations would cost about four times as much per station!  Also I noticed that there is a price break for a full year subscription for the small plan but none for the medium an…[Read more]

Thanks for the input, Dan@wachusett.  I think I figured out my problem – it was the bubbles in the stream as you can see in the attached photo when I was co-locating two sensors! I moved the sensor probe about a foot to calmer waters and now the results look normal.

The MMW server is working now but there is a data gap between 5/12 @15:00 and 5/13 @ 07:15.  Will that data be restored or will we need to rely on the station SD card?

I have been getting “server error(500)” for the last two days on all stations I attempt to load.

@shannon I noticed that the specs for the Hydros 21 indicate 4.0 volts minimum.  The junper on the Mayfly board is set for 3.3 V.  Would you recomend changeing that to 5.0 Volts?

Thanks!  I’ll plug that into my code.

@shannon I am setting up a new sensor station using the hydros 21 (due in tommorow) but I am not using the turbidity sensor.  I deleted that section of the code but I wanted to add the humidity sensor.  What do I need to put in the variable list?  Here is what I have:

Variable* variableList[] = {
new MeterHydros21_Cond(&hydros),
new Me…[Read more]

Some LiPo batteries have the JST connector reversed and that may be your problem.  Check the battery with a VOM to make sure the red wire is + and black is –

@shicks.  I tested the converters you recommended and they appear to work as expected:

dropout voltage is 8 Volts and will support input voltage to 31.5 V (max on my bench PS).

No load draw is 3.64 mA at 12 V and 2.83 mA at 31.5 V.

A lower cost option is a three terminal non-isolated converter at $2.76 ea vs $12 for the PlusRoc.

Thanks!  I just ordered two.  My four port sampler project uses 12V motors which draw about 0.4A so I guess that would be an option to use the 12V output and LiPo 3.7V batteries.

I assume this converter uses switching so it should be reasonably efficient.  I’ll le you know how they work.  Good old amazon – I should get them tomorrow!
