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

Purchased 2017/11/4, out of 4 exterior sensors, 1 sensor went bad this year, 100% success!

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.

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.

This thermometer system is nothing but the best. I purchased it to monitor the temperatures in different places where water pipes may freeze. An added bonus to the system is that customized high and low alarms can be set for each transmitter channel for the temperature and humidity. In my case I set my alarm to warn me if a temperature reading gets too close to the freezing point. Another nice feature is that if a transmitter fails, it can be easily replaced with a new one without the need of replacing the entire system. I live out in the country so I don’t have anybody in range to receive any signal interference from. I have tested the range of the transmitters, which I am certain that operating range can be 100 feet away! The only disadvantage is that the transmitter and the display console use AAA batteries. If you can get past that, this is a great system to purchase!

We had a power outage for 9 days. In order to see what our freezer temps were, we had to open them. Not what you want to do. I was worried this wouldn’t work for how we were going to use it, but it does!! Our big freezer is in the garage which is 30’ from our house. We have 3 of the sensors in our house fridge / freezer / drink fridge, fourth one in the garage freezer. It reaches the main display in the house! I’ve not taken the time to set the min or max temps. But the rest of the set up was easy peasy. I almost sent this back cause when I first opened it I only used one of the sensors. It happened to be the fourth sensor. It wouldn’t show me the temp. Well after I put batteries in the other 3 sensors I was able to finally flip to the 4th sensor (which displays in the same place as the main sensor display, you have to toggle between the two)

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