Thanks all for the feedback. I went out to the site yesterday. One of our staff had switched out a Digi modem for an EnviroDIY modem a while back and plugged the EnviroDIY modem into the Digi adapter board. I wonder if that had something to do with the issue?
I went ahead and switched out the logger, battery and modem as I didn’t have time to properly troubleshoot different components in the field. I’ll test what I pulled at my desktop and will share if I find anything notable.
