Can I mount the outdoor sensor outside?

Does it show a weather forecast?

No. It measures temperature and humidity and keeps daily highs and lows, but it does not forecast.

Can I add a second outdoor sensor?

It is sold as a single-sensor kit. Plan on one outdoor location unless Newentor lists a compatible extra sensor.

Our take on the Newentor Portable Indoor Outdoor Thermometer Wireless Weather Station

The Newentor Portable Indoor Outdoor Thermometer is a battery-powered wireless weather station that shows indoor and outdoor temperature and humidity on a digital display. It records daily highs and lows, has a backlit screen, and can sit on a desk or hang on a wall. It is a small, low-cost unit rather than a full forecast station. At $19.99 at Walmart as of November 7, 2026, it sits at the low end of what compact wireless thermometers cost.
