HI, Alan. Kudos on your "BOOK" for us struggling users of sat.trying to make it work. I am REALLY looking forward to it.
AS to your question, I cannot help direcly and am aslo very interested in other replies. I do wide variety of maintenance services and HVAC monitoring (and some repair) is one of them.
What I DO know works well is a LAND LINE connection. Cell service here is very spotty if at all. My house is in a DEAD ZONE, so I can't even amplify the nonexistent signal. Many of those whom I serve here in Idaho / Canada border keep their land line ON so as to not lose the number, some of which have been the same for generations. THAT WORKS VERY WELL. I can get the name of the product if anyone asks. (I am not at home) Costs under $200 for the phone connection and the thermostat. You can monitor and ADJUST remotely very nicely. WORKS GREAT. Better than snowshoeing in. Some of the houses / cabins have heat in all winter
Blessings to you,
