Adding IOT is just shameless pandering for clicks why not add bitcoin to it :-) I helped build similar devices (custom S100 based systems) 30 years ago at BHR group for remotely monitoring experiments at remote sites and using sensors to monitor pipelines was standard back then. Wish I had suggested we build our own modems out of BYTE for £30 instead of paying £300 for answer and £600 for answer originate.
