We have two Nest E thermostats that are not coming up to temp at the times for which they are set. For example, our first level thermostat is set to be 68 degrees by 6:30AM. At around 9:30 this morning it was only 63. Now, at 11AM, it's 66 and saying it won't be 68 for another hour and 20 minutes. This is the first time I've noticed this issue with the first floor thermostat, though I've noticed our basement thermostat has been behaving this way since this past fall as it got cold enough to need it. We've had these thermostats a while, and they worked perfectly in the past, so it's not an installation issue. As for current settings, Eco Temperatures is on, Nest Sense is off, Time-to-Temp is ready, True Radiant is on/ready, Choose Max Duration is 5 hr (default), Sunblock is on/ready, and Leaf is ready. Thoughts, anyone? Many thanks!
