The CloudNest thermostat costs $129 and installed in about 25 minutes on a standard two-wire system. It needs a common wire for full features, and my 1990s furnace did not have one, so I used the $19 adapter.
Over six weeks the app reported a 9 percent drop in heating run time compared with the same weeks last year, but that winter was milder, so I would not treat that number as savings.
The scheduling is good. The geofencing was unreliable: it marked me away twice while I was home.
