The SwitchBot Meter Pro is the far more capable temperature and humidity sensor of the pair, adding a 3.6 inch display with time, date and a weather trend, a humidity sensor the Nest Temperature Sensor (2nd gen) does not have, and support for Google Home, Alexa, Apple HomeKit, Samsung SmartThings and, through a SwitchBot Hub, Matter. It also costs less and carries the better owner rating. The Nest Temperature Sensor (2nd gen) answers with a longer battery life, about 3 years on its CR2 cell against roughly 1 year for the SwitchBot Meter Pro's two AA batteries, and it does one job well: letting a compatible Nest Thermostat read and prioritize the room it sits in. Choose the SwitchBot Meter Pro for a standalone climate monitor with a screen and broad platform support, and the Nest Temperature Sensor (2nd gen) only if you already own a Nest Thermostat and want it to stop over-heating or under-cooling a specific room.

What the differences mean

What it fundamentally is

The Nest Temperature Sensor (2nd gen) is an accessory with no display or connectivity of its own, existing only to feed a room's reading to a paired Nest Thermostat. The SwitchBot Meter Pro is a standalone monitor with its own screen, sensors and app.

Humidity sensing

The SwitchBot Meter Pro measures humidity alongside temperature. The Nest Temperature Sensor (2nd gen) measures temperature only, with no humidity sensor at all.

Display

The SwitchBot Meter Pro has a 3.6 inch LCD showing time, date and a weather trend. The Nest Temperature Sensor (2nd gen) has no screen of its own; its reading only appears in the Google Home app through the paired thermostat.

Battery life

The Nest Temperature Sensor (2nd gen) runs about 3 years on a CR2 cell. The SwitchBot Meter Pro is rated for roughly 1 year on two AA batteries.

Smart home reach

The SwitchBot Meter Pro connects to Google Home, Alexa, Apple HomeKit and Samsung SmartThings, with Matter available through a hub. The Nest Temperature Sensor (2nd gen) reaches Google Home only, and only through its paired thermostat.

Which one to buy if

What owners say

Owners of both single out how quickly each one sets up, though what each one is being set up for could not be more different. Nest Temperature Sensor (2nd gen) owners describe it solving one specific problem, a hot upstairs or a cold bedroom their thermostat kept misreading, and credit it with real energy savings, while some report the sensor failing to pair with a UK Nest Learning Thermostat. SwitchBot Meter Pro owners build it into a much bigger picture, pairing it with SwitchBot's outdoor sensor to read indoor and outdoor conditions on one large 3.6 inch screen and using its automations to trigger a humidifier or fan, though several note that full Wi-Fi, remote alerts and Matter all need a separate SwitchBot Hub to unlock.
