Home Climate Monitoring

The Taylor STH0A31 kit combines three wireless hygrometer thermometers with a single SBS50 base station. It is designed for households that want simultaneous temperature and humidity tracking in multiple rooms. The system connects to the X-Sense Home Security App through the hub, allowing up to 12 users to view live data and historical graphs from their phones. Builders who need wired sensors or local-only logging will not be served by this cloud-dependent design.

Accuracy And Range

Each sensor measures from 32 to 140 degrees Fahrenheit with a tolerance of ±0.36°F and relative humidity from 0 to 99% with ±2% accuracy. Readings update continuously and the app stores maximum, minimum and average values over 24/7 periods. The Swiss-made sensing element maintains this precision across the full operating span of -4°F to 140°F. Environments that exceed these limits or demand laboratory-grade certification fall outside the intended scope.

Wireless Integration

The base station communicates with the sensors and the app using 2.4 GHz Wi-Fi only; 5.0 GHz networks are not supported. Power comes from alkaline cells rated for roughly one year of operation, with low-battery alerts sent to the app. The hub emits an audible alarm when thresholds are breached and its volume and tone are adjustable. Installations lacking a stable 2.4 GHz signal or preferring Power-over-Ethernet backhaul cannot use this kit.

Questions about this item

Will the SBS50 base station connect to my existing 2.4 GHz router without needing a 5.0 GHz network?

Yes, the base station is compatible only with 2.4 GHz Wi-Fi and will not connect to a 5.0 GHz network.

How can I confirm the three STH0A sensors are reporting accurately after I place them around the house?

Open the X-Sense Home Security App to view live readings; each sensor shows temperature within ±0.36°F and humidity within ±2% RH, and comfort icons on the sensor display give a quick visual check.

Does the package include batteries for the three sensors and the SBS50 base station, or must I buy them separately?

The box contains 3 × STH0A hygrometer thermometers and 1 × SBS50 base station; alkaline batteries are not included and must be purchased separately.
