@vogelrnws I wonder how its going. I see that Teensy is moving to a Teensy4.0 CortexM7

@vogelrnws I had been looking at porting it to another processor and been using it and digging into the code. I’ve looked at some of the RP2040, but I’m cautious about its ability to go into low power – but haven’t looked at it in depth.

The SDI-12 lib uses a software based UART – running at 1200Baud, so 1200Baud is pretty slow and it does handle…[Read more]

@neilh20 @shicks @vogelrnws

Hi all! Thank you for all of your feedback and tips! I spent some time this week looking at the mqtt3.thingspeak.com server and I was able to get a channel up and running on it.

Overall, it’s not drastically different than mqtt.thingspeak.com. The main aspect being removed in the legacy Thingspeak server is the API…[Read more]

@vogelrnws nice to se the layout. That battery holder looks pretty solid and as you said 2 *12V * 9Ah gives 216WHr of capacity. a LiIon at 4.4AH @ 4V is 16Ah.
Its great to have a discussion about the mechanical side, what works, what doesn’t work so well.
Seems like on of the challenges is that uSD is right up against the side of the cabinet -…[Read more]

@vogelrnws Ah, ok! Awesome, thank you. And is there a place to put the apn in the main code?

@vogelrnws Hi there! So I uploaded the files onto the Xbee and used a python editor to change the main.py file. Is there any arduino code you would recommend using alongside this approach?

@vogelrnws Ok, thank you. If you need my email, zholloman54@gmail.com

@vogelrnws I was spending some time looking at the cellular stuff and I decided I’d try to use the python example you used, but I can’t seem to access the files through the Google Drive. Also, I don’t think I currently have a python editor. What is a good one that you would suggest? Thanks

@vogelrnws, thanks for the digi link… this does seem like something that could work very well to send information to AWS from a XBee modem. There are still several steps to figure out in terms of getting a Mayfly program to execute the python code that is on the modem, perhaps like calling a function?, with the sensor data as the message…[Read more]

I wonder if the AWS interface can be done through some form of @vogelrnws  python that runs on the Xbee LTE? JMight be worth looking for something that runs on the raspberryPi in Python for AWS, and then seeing if they could be adapted to Xbee LTE python.  (so easy to throw out an idea – but I have no experience with AWS)

@vogelrnws thanks.  Would you have an overall schematic of it. Sounds like Solar to +12V.  Then guessing +12V battery that is the main power source. Then  Teensy3.5 supply 3.5to5.5V, possibly also Xbee LTE boards

Probably a carrier board for the Teensy3.4 and LTE board?

@vogelrnws, We are using 4G LTE modems that are recommended by EnviroDIY with the LTE Bee Adapter. Verizon will send us SIM cards once we give them a list of IMEI numbers for the modems. Fortunately, our agency has access (with approval) for certain AWS storage/computing services, so I can take advantage of this since this project is relatively…[Read more]

@vogelrnws  sounds great .. the Teensy 3.5 is a great board and amazing support. If you’ve figured out remote upgrade as well, very noce.  I wonder if you would create a separate thread for it ~ perhaps “using the Teensy 3.5”. One of the biggest issues for me is always how to make a system, low power and solar powered.

Thanks for your input @neilh and @vogelrnws.  I work for a state agency, so I have limited options when it comes to IT related endeavors, especially things that are new (like technology from the last 20 years). I am basically trying to follow pathways that have been lightly trodden, rather than attempt to blaze my own trail.

I am in the process…[Read more]

@zeke-holloman do you want to send me the thingspeak details on my email neilh20@wLLw.net and I’ll try them in my setting.  I have a historical thingspeak account which has exceeded its free quota, so I can’t create more devices.

The hologram account should work with the Xbee LTE ( I have an XB3-CA2-UT-001) if setup, and I started with…[Read more]

@vogelrnws Thank you for sending that. I’ll be sure to take a look at it if ThingSpeak doesn’t work.

@neilh20 I tried running the code with your ModularSensors library, and it still didn’t work. The apn I’m using is hologram. If I am using a Hologram SIM card, is that correct, or should I change the source to something else? Also, what is…[Read more]

Hi there @vogelrnws. Honestly, It’d be awesome if you could send that code. I’m still considering my options on the method to publish the data, but that could be helpful!

@neilh20, ok! I’ll try that. For some reason (not really sure why), the code all of a sudden started saying that it couldn’t connect to the internet for clock sync. I’m…[Read more]

@vogelrnws

Hi there! Yeah I registered the MQTT device via ThingSpeak. I used the MQTT Explorer you suggested and I was able to post some data to Thingspeak by typing literal values into the Explorer. This leads me to think that it’s an issue with the Mayfly code.

@neilh2o I’m curious as to how you set up the ThingSpeak using POST. I’m not…[Read more]

Hi there! Thank you @neilh20 and @vogelrnws for all of your help! Yeah, based on what I’m seeing, I don’t think its been connecting at all. I have been checking the channel I’m using whenever I’m trying to connect and no data has been popping up in the fields. It’s only got like, 5 fields, so it’s not too complicated either. Sorry, I’m somewhat…[Read more]
