Ambient Weather WS-10-X4 Wireless Indoor/Outdoor 8 Channel Thermo-Hygrometer with Four Remote Sensors by Ambient Weather

I've had this for a couple days and so far I love it. Setup was very straightforward and it's working great. During setup, all the remote sensors and the base unit were reading the same temp and humidity. Once I placed the remote sensors where I wanted them I had to do a little calibration (I used a Kestryll) but it wasn't a big deal. Since calibration they've been very consistent with the readings I get on my Kestryll. A few notes: - The remote sensors already had the DIP switches set up, which was a nice touch. - The manual says not to use rechargeable batteries, but I think that's overkill except for outdoor sensors in very cold climates. For those, use alkalines. For indoor sensors and for the base unit, rechargeables are fine. I use Eneloops or Amazon Basics rechargeables. - It helps to let the sensors acclimate for 5-10 minutes before making any judgements about whether they're all consistent. Out of the box I had one that was reading 5 degrees above the others, but after a few minutes they were all within a few tenths of each other. - The display on the remote sensor shows which number it's set to (i.e., 1-8) so you don't get them mixed up. - The calibrated temp and humidity are only shown on the base unit. The sensors show the unadjusted temp and humidity. For example if you've got a +2 degree adjustment on a sensor and the base unit is show 62 degrees, then the sensor will show 60. The only two suggestions I'd make for improvement are: - Use soft-touch buttons on the base unit rather than the hard, clicky buttons. - The base unit's screen could use a little more contrast, especially since it's not backlit.

sensors works well with RFXCOM/HomeSeer, 4 sensors at this price = bargain! 1 F007TH sensor = $50

Works great for animal houses

I my first Ambient Weather Wireless 8-Channel Set 9 years ago. It is still working great. One of 4 sensors, the one that has been sitting outside for 9 years and survived through a lot of bad weather, finally lost its hygrometer function, i.e. it shows 20% humidity all the time. Maybe some water got inside. Instead of replacing the 'bad' sensor I bought exact same product (the central panel and 4 sensors). Now I have 2 central panels and 7 good sensors. I can monitor the temp/humidity in every room of the house, in the basement and outside from both the den and the MBR. I recommend it highly. Good bang for the buck.

The reason the four star designation is when the temperature sensors powered up they did not read the ambient temperature the same. Even though they were on the desk top next to each other the temperature they displayed were all different. I expected them to be at most within a 1/2 degree range and they were not. I wanted five areas monitored: outside, in the garage, in the unfinished basement, in the primary bedroom and in the living room. I am knowingly using an indoor unit outside (even though in a protected area where sunlight, rain or snow can not reach it) as such I have had to add a +5 degree addition to the displayed temperature. Ambient WS-10-X4 is nicely made and comes with four sensor units, all wireless and battery powered as is the base station. It does the job just not to the accuracy I desired. While I am not monitoring mission critical areas I still wanted the accuracy. The unit functions as was described in the product description. I acknowledge I am not using it in the manner it was manufactured for. I did not read the product description closely. I had looked at numerous weather sensor packages that could be used outside and I glossed over the fact these are indoor only. So make sure you read the product description and understand what you are ordering.
