The WiFi-enabled Smart Thermostat that connects to the Internet has received its first remote upgrade. New features of software version 1.4 include a password-protected lockout feature, so only authorized users can change the temperature; an updated five-day weather forecast; and an extended temperature range for low- and high-temperature alerts. The auxiliary heat-only system mode allows users to switch to a back-up heat source if their main heat pumps go offline. Thermostats now can be grouped so that changes on one will be made for all in the group, which can be helpful for managing multiple thermostats.
