Criacr Digital Thermometer Hygrometer, Mini Indoor Outdoor Temperature and Humidity Monitor, Wireless Room Hygrometer Gauge with Large LCD Display, ℃/℉ Switch, 328ft/100m Range for Home, Office

The very device I have been looking for. A small device, yet the display is easily read, the numbers are very clear. Distance between sender and receiver is good. In my case 5-6m plus thru an outside wall and into the motorhome. The device allows me to remotely monitor the temperature and humidity in my motorhome over these cold winter months. A minimum temperature warning alarm (ie zero degrees) would be a good addition to the unit but hey, I am happy with what I have got, which was at a good price. I have not checked the accuracy. My motorhome internal guages tell me approx the same temperature and humidity. I need an indication not a precise measurement. As for "warmth" in the features above . . . no idea what this is referring to ? Update June 2021:- The sender remains in the motorhome, with the receiver in the house kitchen. The unit worked well over the winter period. When the outside temperatures dropped below zero, I could see at a glance what the conditions were inside the motorhome, so it gave me peace of mind. The units are still using the original batteries. Still recommended

Initially unsure, going by other reviews, about the accuracy. Followed the instructions and left to settle for an hour and was surprised that there was only 0.4 degrees difference between the 3 readings. Initially there’s was over 3 degrees difference but once settled the 2 readings on this thermometer have remained 0.2 degrees apart and within 0.5 degrees of our fridge thermometer.

This is a great little product. The LCD is crystal clear, and easy to read, with the outdoor temperature being prioritised over the indoor temperature (inasmuch as the former is four times the size of the latter). Setup was ridiculously easy - just put the batteries (not included) into both the display and the sensor, and they automatically pair. My only concern here is whether there might be crosstalk with other nearby units as there doesn't seem to be any way of specifying a channel or identifier. The unit only displays the indoor temperature and humidity, and the outdoor temperature and humidity (the latter is a nice touch as most external sensors only measure temperature). There is no clock. But that's fine - I don't need yet another clock. As other reviewers have noted, the temperature reading seems accurate, when compared side to side with other thermometers including a laser thermometer. Overall I would really recommend this. I might be tempted to get another, for use elsewhere in the house, with the caveat being my aforementioned concern of crosstalk. Update: March 2024 The outdoor sensor has died. But considering I bought this in Aug 2019, I think almost 5 years is probably acceptable and at this price I may as well just buy another.

Worked as soon as the batteries were installed, very easy. seems quite accurate. Intructions say the Celcius/ Fahrenheit switch should not be changed with the batteries installed.

So easy to see what the outside temperature is, from inside

Overall a good value for money basic hygrometer. It’s accurate for giving indoor and outdoor temperature, but that’s it! Very small screen, so not easy to read like my previous one. Also, does not provide humidity status. Fine for indoor and outdoor temperatures.

Excellent device, not too big and doesn’t have the unnecessary displays that most have.

Could have been a great small indoor and outdoor temperature monitor, but very unreliable. My first unit lasted 18 months before the display started to fail. Thought I was just unlucky so purchased another, but the replacement lasted only 3 months before it started to show spurious temperature values (53 degrees outside in Nov) :( Not just bad luck - Don't waste your money
