Nest Temperature Sensor (2nd gen) vs SwitchBot Meter Pro

The SwitchBot Meter Pro is better for most buyers. It measures both temperature and humidity, has a 3.6-inch display, costs less, carries a higher rating, and works with Google Home, Alexa, HomeKit, SmartThings, Home Assistant and IFTTT. The Nest Temperature Sensor (2nd gen) only reads temperature and only works as a Nest Thermostat accessory.

The Nest Temperature Sensor (2nd gen) is a Nest Thermostat companion with no display, no humidity sensing and no integrations of its own, whereas the SwitchBot Meter Pro is a standalone monitor with a large information display, humidity sensing and broad smart-home support.

No. The Nest Temperature Sensor (2nd gen) pairs directly to a compatible Nest Thermostat and has no Wi-Fi, Bluetooth or hub connectivity of its own. The SwitchBot Meter Pro works standalone over Bluetooth, with a SwitchBot Hub adding Wi-Fi, remote alerts and Matter.

The Nest Temperature Sensor (2nd gen) leads here, with a CR2 battery rated for about three years, while the SwitchBot Meter Pro runs roughly one year on two AAA cells.

Existing Nest Thermostat owners with a room that runs consistently too hot or too cold, who want the thermostat to read and prioritize that room and value a multi-year battery over a display or extra integrations.

Anyone who wants a self-contained temperature and humidity monitor with a big glanceable screen, threshold alerts and automations, plus Google Home, Alexa, HomeKit, SmartThings, Home Assistant, IFTTT and Matter support through a hub.
