Hi there! Does the Mayfly have an I2C address associated with it? I’m trying to use Wire.h to transmit data between two Mayflys. If it does, where could I find it, for both the 0.5b and the 1.0. Thank you!

WOW! That’s awesome it worked for you as well. Hope it ends up being helpful!

I will say, it wasn’t a quick process. It was a lot of jumping back and forth between ThingSpeak documentation and code, but I was SUPER excited when it finally uploaded.

Aaaah, ok, that makes sense. Thank you!

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]

Hi there! I recently received an email from Thingspeak stating that they are planning on shutting down their legacy Thingspeak server this month. I’m working to convert my Thingspeak channels over to from mqtt.thingspeak.com to mqtt3.thingspeak.com.

I’m using a Mayfly v1.0 alongside you all’s SIM7080 card. It publishs…[Read more]

Hopefully the fix won’t be too bad.

Thanks for posting that code so quickly! I didn’t have time to look at it until today. I had an older version of Modular Sensors downloaded and so I tried running it with the code you sent and with a few edits in order to get it logging to thingspeak, it was practically plug…[Read more]

Sorry, I know this is a silly topic to start an entire thread after, haha. Was any example code regarding the new Enviro LTEBee’s running off of SIM7080. I was having trouble locating it (I’m still learning Github).

That worked! Just had to download it from the link you sent.

Really excited to start working with the v1.0! Thank you all for your great hardware, communication, documentation, and quick responses!

Hey Neil! Sorry it’s been a while, but just a quick update. I was able to get it to work. I ended up purchasing a new XBee cellular modem (same type) alongside the Digi IoT Development Kit.

Also, I don’t think I currently have a python editor. What is a good one that you would suggest? Thanks

I just had a thought. The fact that the software works with the Digi WiFi S6B. Do you think that means its an issue with the actual cellular connection as opposed to the code?

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.
