Nest Labs is pushing out a v3.5 update to owners of the Nest Learning Thermostat
at 9PM Eastern today. The firmware upgrade includes two new modes, beginning with Cool to Dry, which turns on air conditioning to reduce humidity. A Sunblock setting should meanwhile prevent the thermostat from turning on unnecessarily when direct sunlight is hitting the Nest's sensor.
Improved fan scheduling options let people dictate what hours a fan comes on, and how long it stays on during each burst. Nest is also promising updates to its iOS
apps, which will introduce alert messages and thermostat-style interfaces. To get the v3.5 firmware, a thermostat must have an active Wi-Fi connection.
