This article inspired me and I set out to duplicate what Les did with the Clipper LTE board. After purchasing the Clipper LTE Kit and Pico 2 Plus board from Pimoroni, I was able to get everything working with a small workaround. I have yet to be able to get the 1NCE SIM card that came with the kit registered and connected to a cellular network and therefore had to use a Verizon SIM card instead. Although everything works great with the Verizon SIM card, I would very much prefer to use the 1NCE SIM card because of the cost of data.

Currently I have a DHT11 temperature and humidity sensor connected to the Pico 2 Plus and am publishing the temperature every 30 seconds or so to the MQQT topic, "TomsHardware" using the HiveMQ broker service. I suppose at this time anybody could subscribe to that topic and see the temperature in my office. Additionally, I am able to turn on and off and LED via commands published to the same topic.

I just happened to stumble upon Les's article regarding the Clipper LTE and am happy I did. I messed around with cellular connectivity several years ago but was actually only sending/receiving commands to control my microcontroller remotely using SMS text messages. MQQT opens up some new possiblities that I'm excited about.
