The YoLink Smart Wireless Thermometer Hygrometer transmits up to a quarter mile over LoRa through a YoLink hub. The Sensi Emerson Room Sensor connects only over short-range Bluetooth to a nearby Sensi Touch 2 thermostat.

The YoLink Smart Wireless Thermometer Hygrometer sends temperature and humidity alerts by app, email and text with no subscription. The Sensi Emerson Room Sensor has no remote alerts of its own.

Sensi Touch 2 thermostat owners who want it to prioritize or average an uneven room and value the three-year warranty, without needing long-range monitoring, alerts or broader integration.
