U UNNI Indoor Outdoor Thermometer Wireless Weather Station — Metal Black, 330 ft Range, Backlit Display

The U UNNI Indoor Outdoor Thermometer is a battery-powered wireless weather station that displays precise temperature, humidity, and comfort indexes from up to three remote sensors across a 330 ft range.

This compact metal-black weather station combines a Swiss-made Sensirion sensor with U UNNI's patented wireless transmission to deliver reliable indoor and outdoor measurements. It shows temperature and humidity, plus derived values like heat index, dew point, and mold risk, updating every 30 seconds. The unit offers a backlit, easy-to-read display and supports tabletop placement or wall mounting, making it practical for home, office, greenhouse, or workshop use.

How accurate and wide-ranging are the readings?

The system uses a high-precision Sensirion sensor for tight tolerances and broad coverage. Indoor and outdoor temperature and humidity ranges cover most everyday and extreme conditions, with small error margins to help you track changes reliably.

• Indoor temperature range: +14.2°F to +122°F (accuracy ±0.5°F).
• Outdoor temperature range: -58°F to +158°F.
• Humidity range: 1%–99% RH (accuracy ±2%).
• Updates every 30 seconds for near real-time monitoring.

How far can the remote sensor transmit and how many sensors are supported?

U UNNI's patented wireless technology pushes reliable signals up to 330 feet in open space, letting you monitor distant locations such as a backyard, garage, or detached greenhouse. The base unit can pair with up to three remote sensors—just assign each to a different channel to view multiple spots at a glance.

• Transmission range: up to 330 ft (line-of-sight).
• Multiple sensor support: up to 3 remote sensors.
• Channel switching: ensure sensors use different channels for clear data separation.
• Refresh interval: approximately every 30 seconds for each sensor.

What extra environmental data does it provide and why does that matter?

Beyond raw temperature and humidity, the display calculates helpful comfort and risk indicators so you can act before conditions become problematic. These derived metrics are useful for plant care, avoiding mold risk, and gauging perceived heat or chill in living spaces.

• Heat index: shows how hot it feels combining temperature and humidity.
• Dew point: indicates the temperature at which condensation forms.
• Mold index: estimates relative risk of mold growth from humidity trends.
• Clear display of each metric for each sensor location on demand.

How easy is it to read, mount, and power the device?

The display uses bold characters and a 10-second backlight for visibility in dim areas. The housing supports both tabletop placement and wall mounting, and the included outdoor sensor is rugged and battery-operated for flexible positioning.

• Large, black digits on a backlit screen—tap to illuminate for 10 seconds.
• Tabletop stand or wall-mount option for flexible placement.
• Battery powered (batteries not included in warranty) for easy installation.
• Durable metal-black finish that fits modern interiors.

Who is this for? This U UNNI weather station is designed for homeowners, renters, gardeners, hobbyists, and small-business operators who need dependable indoor/outdoor climate data. It suits anyone wanting clear, actionable environmental readings—especially those monitoring plant rooms, wine cellars, nurseries, garages, or remote structures—without wiring or complex setup.
