Thanks for the responses! Unfortunately, I am still having trouble posting data to the web. I had this working before the switch to Limnotech, so I’m wondering if there are some other changes that I’m unaware of that could be causing the problem.
I’m attempting to post data using the “logging_to_EnviroDIY” sketch on GitHub (after updating the registration token etc in the code…).
My current xbee config settings are as indicated in the readme:
AH – Network type: Infrastructure 
IP – IP Protocol: TCP 
DL – Destination IP Address: 18.104.22.168
DE – Destination Port: 50
AP – API Enable: Transparent Mode
