Same here, but I want to say some bad things about old thermostats. My first house had propane heating, in a big tank that they would periodically come by and fill, so I had a visceral connection to how much fuel I was using. The previous owner had left the original 1960s mercury thermostats running the place, which meant that barring any initiative on my end the temperature was the same no matter if I was sleeping, at work, or whatever else it is people do. When I finally got around to replacing it with a digital programmable one, it cut my propane bill in half. Do you need to hook it to your smart phone? No, that's dumb. Do you need to choose between bleeding money vs. adjusting everything manually as part of your daily routine, like your grandfather winding the hallway clock? No, also dumb. Local digital is the way to go.
