Indoor Outdoor Thermometer Wireless with 3 Remote Sensors, Digital Hygrometer Indoor Thermometer, Temperature Humidity Monitor Gauge with 200FT/60M Range

Work very well. 2 in sheds - over 30 feet from base and always transmit good signal. Very pleased with purchase.

I've had this unit now for 6 months and found it to be really good. Its a nice size and easily readable. In a number of reviews people have complained that you can't change the display on the remote sensor units from Fahrenheit to Centigrade or visa versa - THIS IS NOT CORRECT. Yes you can and very easily. They mistakenly think that by changing the display on the receiver unit it will change the display on the remote sensors as well....it does not. These have to be changed separately. Admittedly the instructions supplied don't really explain it but this is how you do it: - Open the battery cover of the sensor unit. - Just to the left of the '1-2-3' slide switch there is a small hole. - Insert a slim object (ie small screwdriver etc) into the hole and gently press down until you hear / feel a click. - You will now find the display on the remote unit has changed from Fahrenheit to Centigrade or visa versa. - Repeat for each remote sensor.....simple....!! I've posted a video showing how to do it. If I had to be super critical its a shame that you can only view the Max / Min figures for each channel one at a time on the receiver unit and not all at once like my old Technoline unit did. You have to cycle through each channel individually to look at the figures but this is a minor niggle so it still deserves 5 stars in my book.

I wanted to know the humidity in my log store and outside temperature near the cars; does both of these jobs well, but the accuracy is a bit off as it doesn't agree with itself when you line all 4 sensor up on a table next to each other: they can read up to a degree different. I would think that there would be a way to calibrate them better, but don't know how. Wireless connection pretty good. Occasionally one drops out, but the re-connect when brought closer then seem OK still when put back in position.

I wanted to be able to regularly monitor the temperature and relative humidity in my workshop, new log cabin and loft. The main unit sits in my upstairs office so that I can see at a glance if I need to switch on heaters or dehumidifiers in the outbuildings. The main unit also records the temp' and humidity in my office. I found the instructions overly complicated but the actual installation was incredibly easy. I simply popped the batteries into the main unit and then into each monitor numbered 1 to 3 - as I did this they each showed up on the main unit. I then placed each of the monitors in their relative building and checked to see that they were updating regularly. That was it - Job Done !! This unit enables me to see at a glance what is going on without having to climb up into the loft or leave the house - very useful when its dark or raining. I am sure that it will very soon cover it's cost by saving electricity as I don't need to leave heaters on ''just in case''. Monitoring the loft unit has already shown that our investment in improved insulation and ventilation is definitely paying off. The best thing of all is that I now feel I am in control of what is going on 24/7 from the comfort of my office.

In the UK you NEED this product! You just bon’t know it yet!

Excellent. Easy to setup. Works perfectly as described

Doesn’t work, max 3-4 meter range , doesn’t connect after 3-4 meters, waste of money

Accurate temperature readings with good transmitting range.
