X-Sense STH0A Wi-Fi Thermometer Hygrometer with LCD

Wi-Fi: The X-Sense STH0A is an indoor thermometer hygrometer with an LCD, battery power and app-based monitoring when paired with the separate SBS50 base station. Its display shows temperature and humidity locally, while the app claims include graphs, alerts and plant-related dew point and VPD readings. Buyers wanting app access should factor in that hub requirement.

The stated temperature and humidity accuracy ranges provide concrete guidance for indoor monitoring.

What to know before buying

Listing details to confirm

The app and remote functions require the SBS50 base station, which is not included. The listed 1-pack contents specify one STH0A sensor. The listing's colour field instead describes the sensor and excluded base station, so treat that field as a bundle clarification rather than a colour description.

Aggregate ratings are strongly positive overall, with most ratings in the five-star category, but a smaller spread of lower ratings shows that experiences are not uniform. No review comments are supplied, so these figures do not identify specific strengths or problems. For buyers, the separate SBS50 requirement remains an important practical condition regardless of the rating profile.

Frequently asked questions

Does the STH0A provide app monitoring on its own?

No. The listing says the SBS50 base station is required for app features and is not included with this one-sensor pack.

What does the display show?

The listing describes a 2.7-inch LCD showing temperature, humidity, Wi-Fi and battery status, and a comfort indicator. It also says the unit has a Celsius and Fahrenheit switch.

Can it be used outdoors?

The listed usage is indoor, so this is not presented as an outdoor monitor.

What are the stated accuracy figures?

The manufacturer claims temperature accuracy of ±0.36°F (±0.2°C) between -4°F and 140°F (-20°C to 60°C), and relative humidity accuracy of ±2% between 0 and 99%.
