Smart thermostat with remote sensor

The fourth-generation Nest Learning Thermostat Pro Edition includes a second-generation Nest Temperature Sensor to manage comfort in a specific room. It targets homeowners who want automated schedule learning and app-based control for most 24V heating and cooling systems. The package supplies the thermostat, a trim kit, sensor, CR2 lithium battery, screws and box for a complete self-install.

Polished silver finish with larger display

A polished silver dial and a display 60% larger than before give clear visibility across the room, while Dynamic Farsight shows a clock or weather view automatically. Brightness adjusts itself for readability or can be set manually. The thermostat works with Alexa, Google Home and Matter, so voice and phone control fit into existing smart-home routines without extra bridges.

No C wire needed for most 24V systems

Installation proceeds without a common wire in the majority of homes, supporting gas, electric, oil, forced air, heat pump and radiant configurations. The thermostat requests permission before changing schedules and sends notifications to the Google Home app for one-tap approval. Buyers whose systems fall outside standard 24V wiring or who require multi-zone control beyond a single remote sensor should verify compatibility first.
