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

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.

It seems reliable so far after using it for 6 months. The 4 remotes were reading all within a degree from each other and can be adjusted on the main unit if needed. I like that they report both degrees and humidity. We use it to measure temp/hum in our garage, inside two dog kennels in the garage and in our heated doghouse out in the yard. The main unit is inside the middle of the house and is about 60ft away from the farthest remote that’s in the yard kennel. It has no problem maintaining contact. I do also like the flexibility they built in to let the user determine how they want the 4th remote set up: you can set it to alternate between the main unit (so in our case the house temperature) and the 4th remote. But you can also set it to just show the main unit or just the 4th remote (we set it for this last option). I want to compliment the manufacturer for building in this option because too often nowadays we’re dictated by software programmers working in their little cubical how to use our stuff... The only point for improving I can think of is to make it a bit easier to differentiate between temp and humidity. The display has nice large numbers but they are the same size and shape for both temp and humidity . Maybe make the humidity a little but smaller?

Whether you're like me making decisions about passive cooling in your home, or just curious what the temperature is in different places in, around or outside your home, the Ambient Weather Station has you covered. The radio sensors work really well and have a great range. I made wooden mounts for them so I know they're reading the Air temperature rather how warm the walls are. Easy to set up, easy to configure and all of the sensors connected right away after I plugged the batteries in the Weather Station. One thing I wish - I know it would shorten battery life, though a backlit screen would be amazing. It is hard to read in low-light.

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 is well made and has a good manual. I had two issues. One display digit was not showing. I have an electronics design background and have used "zebra strips" and was sure this was the issue. This is a rubberized strip making electrical connection between a row of contacts on a circuit board and matching row of connection points deposited on the LCD display. I think a screw mounting the board was too tight warping it just a little preventing full zebra stop contact its full length. Three of the remotes read identically and one a half degree more - excellent and were correct. The base station read about 2 degrees high but that is within specification. It is easily user adjustable so now everything is matched. Typically, a temperature error in something like this is an offset error so the adjustment corrects throughout the range. I might have given it 4 stars due to the minor issues I had, but I think it is a 5 star product, especially for the price.
