Hi,
Thanks for the quick reply! I am not getting any red lights on the modem at all. I have the Mayfly plugged into my pc right now and the only lights are the orange charge light, the USB/POWER lights, and D8 is lit up as green right now.
The modem seems to be correctly seated according to the instructions. We previously were able to get this…[Read more]

Does the red power light on the lower right of the modem turn on? If not, the modem isn’t getting power. Pin 18 should be the right pin number. I’m not sure why it wouldn’t be powering up. Have you ever messed with the solder jumpers?
If the modem is powering up, you might have a baud rate problem. Try setting the modemBaud to 57600 even…[Read more]

Also double checked hologram.io to check to see if the sim is active, it is. I’ve also tried swapping the battery out, taking the sd card in/out, and have messed around with
const int8_t modemVccPin = 18;
and have swapped it from 18 to -1 as per the commented code, but it has not worked.

Hi,
Continuing to run into a problem connecting our Mayfly to LTE, getting an error: “Could not wake modem for clock sync”.
I’ve seen this posted a lot but I still can’t find any concrete reasons as to why I’m getting this error. I’m using the “DRWI_SIM7080LTE” sample sketch and using a HYDROS 21 to connect.
I’ve generated, formatted, and…[Read more]

Hi Paul! Thanks for suggesting a biennial subscription. I’ve added it as an option for each of the plan levels.
You have the ability to modify your subscription, so if you need to change to an annual plan after two years, you can do that from your Monitor My Watershed Shop account.

Nevermind! We’ll just buy the 6600 mAh battery
Elliot Ma started the topic Buying new batteries + sim card problems in the forum Mayfly Data Logger 1 year, 11 months ago
Hi,
We’re looking to buy new 3.7 V 4400 mAh batteries for our Mayfly 1.1 and it seems that both the Adafruit and the Digikey vendors on the parts list table are both sold out. Any recommendations on replacement batteries that we could look for or are we okay with buying any general 3.7 V 4400 mAh batteries we can find that have similar…[Read more]

I’m thinking ahead to 2025 and beyond. I have funds available until early next year (2025) that I can use to pay for EnviroDIY web hosting. My question is can I pay a year in advance? For example in December 2024 can I pay for both 2025 and 2026 (Medium annual plan) OR is it only possible to pay for 2025 at that time. Thanks. Paul
