GoveeLife Hygrometer Thermometer H5104 vs Nest Temperature Sensor (2nd gen)

Full Smart Temperature/Humidity Sensors comparison in 2026

Updated October 2026
Data from Amazon and official Govee and Google sites.
2026 verdict
While the Nest Temperature Sensor (2nd gen) only exists to steer a Nest Thermostat, the GoveeLife Hygrometer Thermometer H5104 is the better temperature and humidity sensor on its own terms.
It adds humidity sensing, a 3.1 inch LCD, temperature and humidity alerts, automations, history records and a 1.5 year warranty, and it works with Home Assistant over Bluetooth. The Nest Temperature Sensor (2nd gen) measures temperature only, has no screen, no alerts and no history of its own, and pairs only with a compatible Nest Thermostat; what it offers in return is a rated 3 year battery on a CR2 cell and a 37 g body that disappears on a shelf. Buy the GoveeLife Hygrometer Thermometer H5104 to watch a room's temperature and humidity, and the Nest Temperature Sensor (2nd gen) only to tell a Nest Thermostat which room to heat or cool.

What the differences mean

Standalone sensor or thermostat accessory

The GoveeLife Hygrometer Thermometer H5104 works on its own through the Govee app and Home Assistant. The Nest Temperature Sensor (2nd gen) connects only to a Nest Thermostat, so without one it does nothing.

Humidity

Only the GoveeLife Hygrometer Thermometer H5104 measures humidity. The Nest Temperature Sensor (2nd gen) reads temperature alone, which is all a thermostat needs from it.

Screen, alerts and history

The GoveeLife Hygrometer Thermometer H5104 shows its readings on a 3.1 inch LCD, sends temperature and humidity alerts and keeps a history. The Nest Temperature Sensor (2nd gen) has no screen, no alerts and no history; everything it measures shows up on the thermostat.

Battery

The Nest Temperature Sensor (2nd gen) is rated for 3 years on a single CR2 cell. The GoveeLife Hygrometer Thermometer H5104 runs on two AAA batteries and Govee does not publish a rated life.

Which one to buy if

What owners say

The two groups buy these for different jobs, and it shows. GoveeLife Hygrometer Thermometer H5104 owners praise accuracy that matches between units, a readable screen with min and max values and the app's exportable history, which some use to settle humidity disputes with a landlord or track a greenhouse; their complaints are that it is Bluetooth only, so remote monitoring needs a Govee hub, and that it works with no voice platform. Nest Temperature Sensor (2nd gen) owners talk about comfort: a Nest Thermostat that finally targets the room people are in, and lower bills from scheduling by room. Their warnings are about compatibility, with UK buyers in particular reporting it would not pair with their Nest Learning Thermostat, and pairing that sometimes hangs before it finishes.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
