The X-Sense STH0A is a device that measures temperature and humidity, and it can connect to the SBS50 station to monitor several rooms, store data, and send alerts remotely. The tested kit includes four sensors, eight AA batteries, a SBS50 station, its power adapter, and a USB cable, with a suggested price of 90 euros. The STH0A can also be bought alone for 25 euros without the station. The SBS50 station can manage up to 50 devices, including up to ten thermo-hygrometers, and also works with smoke detectors, heat sensors, carbon monoxide detectors, or water leak sensors. The STH0A has a white square casing (also available in black) with rounded corners and a 2.7-inch LCD screen that mainly shows temperature and humidity. The screen includes icons for battery level, signal strength, and comfort, with a smiling face showing that the readings are within the set range. The device can be placed on a shelf, held at an angle with a foldable base, or mounted on a wall. It runs on two AA batteries, with X-Sense stating it can last up to a year. The product is claimed to have a five-year lifespan. To set up the system, the SBS50 station is plugged in and added to the X-Sense app by pressing its button for five seconds. Each thermo-hygrometer is added individually by placing it within two meters of the station and pressing its top button twice. X-Sense states that in an open space, the range between sensors and the SBS50 can be up to 500 meters, though this might be reduced in a house due to walls, floors, and metal objects. The X-Sense Home Security app (available for iOS and Android) acts as a central hub for home devices, showing the latest temperature and humidity readings, battery status, and signal quality. The app also provides more detailed data like dew point and vapor pressure deficit (VPD), and allows users to view historical data by the hour, day, week, month, or year. Users can set temperature and humidity thresholds and receive alerts if these limits are reached. The app also lets users calibrate temperature and humidity sensors and integrate with Amazon Alexa for voice control. More advanced users can access sensor data in Home Assistant using community integration from HACS. However, the SBS50 station only works with X-Sense devices and does not support other platforms like Matter, Apple Home, or Google Home. The X-Sense STH0A provides clear temperature and humidity readings and comprehensive remote monitoring. The app is easy to use, with customizable thresholds and alerts. The set of four sensors with the SBS50 station offers a cohesive solution for monitoring multiple rooms or existing X-Sense setups. More advanced weather stations like Netatmo or Netatmo Original offer extra features such as outdoor measurements, atmospheric pressure, CO2 levels, noise, and indoor air quality, but they are more expensive and do not include a screen.
