I've had my 3rd gen Nest Learning thermometer for several years. This past winter I've noticed that when it goes into Eco mode the temperature consistently falls below the minimum temperature I set in the app. For instance, I set the minimum to not fall below 65 degrees, yet it consistently dips to 61, 60, 59 degrees unless I wake it up or manually change the temperature. I've had my furnace serviced and all sensors appear fine on that end.
Has anybody run into this issue? No matter how many times I reset it, etc. the thermostat will not rest at 65.
