@panda Thanks for the input. My first thought was Hologram due to lower cost to get started. Long term commitment to data plan is another issue which I am not sure of. At this point, I am going to be trying lots of different things to arrive at a configuration that works for me. In a perfect world (lots of time and money) I would try both with two different setups connecting to the same sensor network and using the same code. Since my world is far from perfect, I thought I would ask. Hearing your experience with Hologram helps... functionality is also high on the list, and it seems like it is working good for you.
