Review on 🌡️ ORIA Indoor Outdoor Thermometer with 3 Wireless Sensors: Digital Hygrometer & Temperature Humidity Monitor Meter for Home, Office, Bedroom - LCD Backlight, Black by Susan Forrest

I bought 2 of these. I placed 3 thermometers from the 1st set outside in my greenhouse and the other 3 from the 2nd set in the 2nd floor bedroom. I had the first set outside in my greenhouse for a few weeks before buying the second set. It seems to be working great. After I received the second set, both displays only show one of the sets. So both display the same thing (except for the top display for room temperature/humidity). Very unpleasant!
