@mbarney, do you know if the REVX plan/sim card you had success with is the CATM version (50mb for $5) or the 4G version (10 mb for &12)? With the new modems I have not been able to register on the network (cereg 0,3) using the 4G plan and sim that worked for a couple years with the old xbee modem.

@shicks,  RevX systems technical support has…[Read more]

@mbarney, thanks for the settings.   What was the sim supplier that you used – a Verizon direct, or an MNVO like REVX.

I did get an email earlier this week from SimCom that there 7080G was now certified by Verizon, so good to know it works 🙂

@mbarney on Mayfly 1.1 I connect SJ17  – that enables the Blue Network Status LED, and indicates the progress of the LTE-CATME connection.   Off – no power,   ( I think)  ON – attempting connection,   FLASHING – connecting

@mbarney just wondering did that work for you with the Mayfly1.0 .  Do you have any changes you made to the program. Many thanks

@mbarney and others,

After doing some research, we decided that shutting down our old servers for 30 minutes would not likely force the DNS on devices to refresh.

Our plan is to set up proxy forwarding on our LimnoTech server to instantly forward all data to the AWS servers. We plan to do that today, and will also set up a forwarding log to…[Read more]

@mbarney, wouldn’t that have been great if the Hologram pause worked! Thanks for trying it out!

Have you seen any of your sites start reporting again in the last 24 hours? The couple that I’ve been tracking have not, which is disappointing. I definitely recognize how painful it would be to manually power cycle these stations.

We’ll likely try to…[Read more]

@mbarney, @neilh20, thanks for pinging us.

As @heather mentioned, we released MonitorMW v0.12 yesterday at that time, which has some major under-the-hood improvements to substantially improve reliability, including now being hosted by AWS (zone: us-east-2; Ohio). For details read  our v0.12.0: Update to Python 3.8 & Django 2.2; Migrate to AWS…[Read more]

Hi @mbarney and @w3asa, LimnoTech’s team is working hard on a fix. Please see my reply on Matt’s other post for a bit more detail.

@mbarney, @neilh20, thanks for your posts. The switch from the LimnoTech server to Amazon Web Services happened shortly after 13:00 EST on December 7. LimnoTech’s team is seeing that their production server is still receiving data from devices, which means that data is not going to the new AWS production. @aufdenkampe and his LimnoTech team are…[Read more]

@mbarney Hello Matt,

I am running into a similar problem with my Maxbotix sensor code…having difficulty integrating the code into my DRWI modular sensor code…. do you mind sharing coding tips to add this sensor module?

@mbarney & @neilh20, the CSV downloads are not an effective way of accessing data gaps, because that mechanism relies on the same corrupted catalog crosswalk that underlies the problem with the sparkline plots.

There are really only two ways for you to assess data gaps:

• Keep a record of server response codes from RESTful POST requests, from…

The sensors the student ordered have the stereo plug and a red cable.

@neilh, we have a calculated temperature compensation in Modular Sensors if you ever need it. It’s extremely negligible in groundwater temp ranges.

@mbarney, the Meter discrepancy is a bit annoying. Was your March order a bare wire or stereo plug?

@mbarney  its a common problem with low power, sleep circuits.

Just to be clear/restate what the issue is. When in “sleep” mode and powered off, all instrument pins (and actually all other processor pins) need to be set to output low, or input with preferably pull down.

On power-up, the pins are activated output and set high within 50mS so as…[Read more]

@mbarney the trace looks good for the waking portion. What I see on  my system is that it wakes every minute and then sleeps inbetween.  So if you have it on a 15minute setting it will do above, then sleep/wake 14times. The current can be read when it goes to sleep.

For the differential case I would think you would have two sets of dividers.  BT…[Read more]

@mbarney an observation, the power is being turned off on the off board ADS1115, but not for the Turner. The ADS1115 Analog inputs are only specified for Vdd+0.3V. If either of the Turners inputs are above this, then it will feed through to the ADS1115 Vdd  Sw5V.  Probably won’t account for what your are seeing.

I found a I needed to know when i…[Read more]

I’m sorry I’m late to this.  But @mbarney the problem with turning off power to I2C devices isn’t universal.  It depends on how your external I2C device is wired.  If the SCL and SDA of your external device are directly pulled up to the incoming Vcc, then when you turn off the switched power, suddenly the system SCL and SDA will be pulled *<…[Read more]

Hi @mbarney  I have come across the I2C issue, and trying to remember what I did, or solution. There was an update that  could fix it, but of course that is a fork.

It might have been that a wrongly soldered I2C for a humidity device caused the problem for me. Arduino paradigm is typically normal use cases.

The Mayfly 0.5b has pullups R8 & 10 o…[Read more]

Thank you @mbarney!  That’s all correct!

And just FYI, prior to version ~5 of PlatformIO, libraries were only updated in the PlatformIO registry when the registry crawler got to it and noticed the change.  So sometimes it would be a day or two before you could see the updates using the pio lib update or similar commands.  With the current ve…[Read more]

Hi @mbarney, I’m combing through the forum topics with no replies, hoping to get some answers for folks, and found this one you posted last July. I’m sure you already discovered this, but the three example code links you listed no longer return 404s. Perhaps @srgdamiano was reorganizing the examples at the time?

• DRWI_CitSci.ino
• DRWI_LTE.ino

Haha, that worked! Thanks @mbarney.
