Dave, thanks for this. It is interesting. Do you know more about it? Do you need a cellular carrier/SIM card? I’m curious how they’re transmitting the data, i.e., on whose network. It’s not clear from their web site, and I can’t find anything in their specifications (or I’m missing it, as it’s still hard to me to understand all these communication protocols).
