## Description

Made with a plastic outer casing, the YoLink YS8003 monitors indoor temperature and humidity and sends alerts through the YoLink app when readings reach criteria you set. LoRa connectivity helps the sensor communicate across areas that can be challenging for residential Wi-Fi, including basements, sheds and detached garages.

Pair it with a YoLink Hub to connect to the app and access third-party integrations with Alexa and IFTTT. The app displays current readings and historical graphs, giving you a practical way to check room conditions and see how they change over time.

## Where it shines

Use the sensor to keep an eye on rooms or equipment where changing temperature or humidity matters. Set personalized alert criteria and receive email or smartphone banner notifications when a reading reaches a preset value. That makes it easier to stay informed about spaces such as a basement, porch, shed or free-standing garage, including locations where Wi-Fi coverage may be challenging.

For example, place the sensor in a room where humidity needs monitoring, then use the app to review current conditions or look back at historical graphs. If you want a response to happen automatically, YoLink automation can pair readings with compatible YoLink Smart Plugs or Smart Mini-Plugs to operate a connected device, such as a dehumidifier. Those products are sold separately.

## Highlights

LoRa provides long-range, low-power communication for the YoLink system. The sensor can also be paired with a YoLink Siren Alarm for an attention-getting alarm. App alerts are adjustable to your criteria, so notifications can reflect the conditions you want to monitor rather than requiring you to check readings continually.

The sensor is battery powered, and its low power consumption supports battery life of up to 2 years or more depending on use and activity. It uses standard AAA alkaline batteries, lithium batteries are not required. A digital display type is listed for the sensor, while the app provides current temperature and humidity readings alongside historical graphs.

## Tips for day-to-day use

Start by connecting the sensor through a YoLink Hub, the central controller that links YoLink devices to the internet and cloud. The hub is required for app access and Alexa or IFTTT integration, and it is not included with the sensor. Once connected, choose alert criteria that suit the room or equipment you are monitoring. You can then use the app to review readings and receive email or smartphone banner alerts when a preset value is reached.

## Before you decide

**Does the sensor work with the YoLink app on its own?** It needs a YoLink Hub to connect YoLink devices to the internet and cloud. The hub enables app use and third-party integration with Alexa and IFTTT, it is not included with this sensor.

**How do temperature and humidity alerts work?** Set your preferred criteria in the app. The sensor can send email and smartphone banner notifications when a preset value is reached, and the app displays current readings and historical graphs.

**Can it trigger another device?** Yes. YoLink automation can pair the sensor with compatible YoLink Smart Plugs or Smart Mini-Plugs to trigger actions, such as turning on a dehumidifier when humidity is high. Those devices are sold separately.

## When it makes sense

A solid pick if you want app-based temperature and humidity monitoring in a room or outbuilding, with configurable notifications and the option to build YoLink automations. Its low-power LoRa communication and historical graphs make it useful for keeping track of changing conditions beyond a quick spot check.
