Part of the appeal of smart appliances lies in them being "smart". Let's face it. As fancy as a smart TV, smart bulb, or smart thermostat may sound, we really do not need another "smartphone" fixed on our walls or ceilings to complicate our lives. That's why Nest Labs is continually trying to improve the "learning" part of its smart appliances, starting with the latest 4.3 software update for its Learning Thermostat. Now users will no longer have to worry when lifestyles or seasons change, as the thermostat changes with them quickly as well.
