The AMIR is a two-piece weather monitor: a battery-powered base station that shows indoor temperature and humidity, plus a wireless sensor that reports outdoor readings from up to 330 ft away on a clear line. The base also shows dew point, heat index, a mold index, daily high and low values, trend arrows and simple weather icons, and it accepts up to three sensors though only one is included. Accuracy is quoted at ±0.5°F and ±2% humidity in the normal range, which is tighter than many budget units that drift a degree or more. It suits people who want a quick read on a room and the yard without an app or Wi-Fi setup; it is not a full weather station with wind, rain or barometric history.

Rated 4.7 out of 5 across 76 ratings, buyers mostly report it does the basic job reliably and is easy to set up. Complaints are few and tend to be about the battery-only power and the single included sensor.
This weather station pairs an indoor display unit with a wireless outdoor transmitter. The main unit shows indoor temperature in °C or °F, along with indoor and outdoor humidity. It also shows outdoor temperature, weather icons, and a low battery indicator.
The display tracks maximum and minimum temperature and humidity values. It also shows outdoor temperature and humidity trends, a mold index, dew point, and heat index. The main unit supports up to 3 transmitters at the same time, but the package includes only 1.
The transmitter sends readings to the main unit over a 433 MHz radio link. It has an IPX4 waterproof rating. Both units update temperature and humidity every 30 seconds, and the atmospheric pressure weather reading updates every hour.
