Review on 🌡️ KeeKit Indoor Outdoor Thermometer: Digital Hygrometer Gauge with 3 Wireless Sensors for Home, Office, Restaurants, Bars, Cafe - LCD Backlit Display and Min/Max Record by Keith Cannon

I can see the outside temperature and humidity with a device mounted under my patio railing through a few walls and 40 feet from the base. What really amazes me is that I can control the temperature/humidity in my barn fattening workshop from across my house. The total distance from the base unit is approximately 75 feet through 4 interior walls, exterior wall, metal siding and exterior wall. from the barn! Incredible performance from this kit! Allows me to turn on the store heater and wait in a warm house until the store is warm enough without having to pack up and go to the store to check the temperature.
