I agree completely! but not everyone offers BW upgrades at all and if you are cracking into the code or making small changes on the board you'd have to know a lot about the design to be sure you were getting correct cal constants and the like.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
