@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?

Awesome, thank you. That worked

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

it seems I have to add your contact email to allow the share. I’ll see if I can post the zip file. It didn’t like the .py files before

@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

I misspoke on the DC/DC supply. It is a Meanwell DDR-15G-5. Pic of the guts on that polycase is attached.

@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]

Thanks, good for reference – the critical aspect of any plastic outdoor box is I understand polycarbonate and those IP65 seals 🙂 Keep out the falling rain. Those ants like to get in if they can, so it is a challenge. I really appreciate the detailed guide of what to think about with https://www.envirodiy.org/mayfly-sensor-station-manual/…[Read more]

We use a polycase 12x10x6 customized enclosure for under $85 with everything predrilled https://www.polycase.com/yh-121006.

We made a custom din rail bracket to hold the two batteries. 10W panel for solar but charger will accommodate up to 30W

Ahh very nice.  I’m sure its worth it to get a standard design for all climates, and able to cope with keeping some sensors warm.   Seems like the cost is going to go up dramatically though. Powering is a lot of cost and of course IP65 space is costly (for those batteries!!).  I wonder if it is open sourced, or a private contract design.  I use…[Read more]

AWS for Xbee

https://www.digi.com/resources/documentation/digidocs/90002219/container/cont_aws.htm

12V to 5V is a DC/DC Din Rail supply P/N: MDR-20-5. The board takes in 5V and and has a 3.3V LDO onboard for those 3.3V parts that pull more than the teensy 3.3V output can provide.

@neilh,

Yes, we have solar to the charger and into (2)12V 9aH batteries (in parallel). The Teensy and Xbee are on a custom motherboard we designed. Has lots of the IO broken out and spots for Adafruit GPS, RTC battery, ESP32 (older requirement) and Wiz850io Ethernet.

See pic attached

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?

Teensy 3.5 topic set up.

@Both

Working on the google drive link for the XBee files if either one of you want them in the future.
