Sensi Emerson Room Sensor vs X-Sense STH0B Smart Thermometer Hygrometer

The X-Sense STH0B Smart Thermometer Hygrometer for general monitoring, since it adds alerts, dew point and CSV history at a lower price. The Sensi Emerson Room Sensor is the better buy only if you own a Sensi Touch 2 thermostat and want to average room comfort through it, where its three year warranty also helps.

The parent device each one depends on. The Sensi Emerson Room Sensor is a Bluetooth accessory of the Sensi Touch 2 thermostat with no integrations of its own, while the X-Sense STH0B Smart Thermometer Hygrometer reports through an X-Sense SBS50 base station and supports Alexa and Home Assistant.

No. The Sensi Emerson Room Sensor connects over Bluetooth specifically to a Sensi Touch 2 thermostat and has no standalone Wi-Fi, Zigbee, Z-Wave or Thread radio. Without that thermostat it has no job.

Yes. The X-Sense STH0B Smart Thermometer Hygrometer has no Wi-Fi of its own and communicates over a proprietary 868 MHz radio, so an X-Sense SBS50 base station is required to receive the readings and pass them to the app.

The Sensi Emerson Room Sensor, at three years. The X-Sense STH0B Smart Thermometer Hygrometer is covered for two years.

No. The Sensi Emerson Room Sensor has no smart home integrations of its own, and the X-Sense STH0B Smart Thermometer Hygrometer supports only Alexa and a community Home Assistant integration. Neither supports Google Home.
