<div id="video-block-RNV5ZRMP5PORX" class="a-section a-spacing-small a-spacing-top-mini video-block"></div><input type="hidden" name="" value="https://images-na.ssl-images-amazon.com/images/I/D1tco3MuIGS.mp4" class="video-url"><input type="hidden" name="" value="https://images-na.ssl-images-amazon.com/images/I/61GUBYqZogS.png" class="video-slate-img-url">&nbsp;Pros:
- Well laid out display that can be configured to display most of the temperature information anyone would desire.
- Additional weather related information is also displayed that most casual weather observers would want to know (barometric pressure, phase of the moon, etc.)
- Access to simple functions is straightforward.
- Provides alarms based on time, temperature, humidity, dew point, (and on WS-11 barometric pressure.)
- Most data sources can be calibrated.
- Once calibrated, sensors are accurate within Ambient Weather specifications.
- The back-light changes color to reflect either the indoor or outdoor temperature if desired.

Cons:
- Console displays a lot of information and is a bit busy.  It is difficult to view for those with vision impairments.
- The graph function is limited by the resolution of the LCD display.
- Accessing some of the more advanced features isn't particularly intuitive, so that infrequent use will probably require consulting the manual.
- The alarm functionality only applies to the first external temperature and humidity probe.
- The WS-110 is limited in the sort of information in can provide by the nature of the sensors it uses.  It is a very capable device for monitoring temperature data, but could be a disappointment if the owner has more general weather interests.

I received a pre-production version of the Ambient Weather WS-110 to review and test.  Actually, I first received a WS-11, however unfortunately the console was not working.  Such failures are to be expected in the development process and Ambient Weather sent me a replacement console by second-day air.  That is certainly commendable customer service.

This reviews includes a video that contains 2 photographs and 4 video clips of the WS-110 in various modes of operation.  Because it was impractical to eliminate the background noise, the video is silent.  Practically speaking all that is missing is the audible confirmation of the button presses.

If you are interested in either the WS-11 or WS-110 I urge you to download a copy of the documentation so that you can go though the available features.  At the time of this review, the documentation wasn't on the Amazon product listing, but you can download it from the Ambient weather website.

Where appropriate, the review video includes a citation to the manual section for the feature that is being demonstrated.

Even if the packaging was also pre-production, Ambient Weather had already come up with an eco-friendly design that used mostly cardboard and had an absolute minimal about of plastic to product the fragile electronics.  Included in the video is a photo of the packaging.  Setting up the WS-110 is straightforward if you follow the manual instructions.  One thing to keep in mind is that this device requires 4 AA batteries for the console and 2 AAA batteries for the remote temperature and humidity sensor.  Batteries are not included in either unit.

The WS-110 and WS-11 are very similar.  The main difference is that the WS-11 includes a forecast based on barometric pressure and allows for alarms based on barometric pressure.  If you are interested in this model, keep in mind that barometric pressure is a limited mechanism to forecast the weather and can be particularly unreliable in areas like California.  If you really are interested in getting a warning of possible severe weather, you would be far better served by purchasing a weather radio that can receive alerts from the National Weather Service such as the Ambient Weather&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-WR-091-Rechargeable-Emergency-Pocket-AM-FM-WB-Weather-Alert-Radio-with-Digital-Tuner-Flashlight-Headphone-Jack-AC-Adaptor/dp/B00EYI8GTQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather WR-091 Rechargeable Emergency Pocket AM/FM/WB Weather Alert Radio with Digital Tuner, Flashlight, Headphone Jack, AC Adaptor</a>.  Such alerts are generated by professional weather forecasters with access to much more data than barometric pressure alone.

The WS-110 omits the barometric pressure alarms and forecast icon and instead has an indication of the phase of the moon.  This might be a better chose especially if you are in a part of the world were barometric pressure is a poor predictor of the weather.

Both the WS-110 and WS-11 come with a F007TH wireless thermo-hygrometer.  A photograph of this device is included in the video.  Either console can display data from up to 8 devices like this.  You can mix and match the following devices: the Ambient Weather F007TH thermo-hygrometer, the F007PF floating pool and spa thermometer, the F007T temperature sensor, and the F007TP temperature probe.  We already have in operation a F007TH wireless thermo-hygrometer from an WS-07 console, so I configured the new F007TH with the second device ID. As designed, the WS-110 found both probes and started displaying their data.  As you can see in the first clip on the video, a very pleasant way to keep an eye on your environment to have the console in so called "scroll" mode which has it display all external probes one after the other in 5 second intervals.  The ability of having 8 temperature probes opens up a wide range of potential applications.  I intend to put the second thermo-hygrometer in the attic to monitor the effectiveness of attic fans.  If you are interested in improving your energy efficiency, this is a way to monitor temperatures in multiple locations.

I compared the accuracy of the instruments against our Davis Vantage Pro-2 weather station and the indoor and out temperatures were accurate to the specifications of the devices.  I also made some tests to confirm the range of the remote sensor.  Taking the F007TH to the far end of the yard, over 200 feet, did not cause the signal to be lost.  I then placed the F007TH inside the steel glove compartment of our 1965 Buick wagon that was in the garage.  The heavy steel construction of a 50 year old example of Detroit muscle did not block the signal.  So for most uses, you should be able to place a remote sensor a any desired location.  One thing to keep in mind though is that the number of wireless devices is constantly multiplying.  Most homes nowadays have Wi-Fi, wireless phones, and perhaps wireless music relay devices.  You may have some problems with interference between the all the wireless devices in your home.  These Ambient Weather devices use the 433 MHz band.

Both the WS-11 and WS-110 have a very elaborate system of adjusting back-lighting based on the temperature.  It attempts to emulate our own intuitions of which colors would correspond to different temperatures.  I suppose some people will find this feature really cool, but honestly it feels a bit silly to me.  In order to experience this feature you need to look at the console and course you could just as easily read the temperature value to a tenth of a degree.  However, if you find this feature appealing it is designed with care and can be customized to the point that you can have the colors progress in a range suitable for your climate.  If you are a pragmatist like me, you can select a single color and that is probably preferable for ease of reading.

One of the features of both the WS-11 and WS-110 that is of limited value is the graphing feature.  There simply isn't enough resolution in the LCD display to make much sense of the graph.  The third clip on the video cycles through the available graphs.  This is rather commonplace as many weather station consoles suffer from the same limitation.  The only station I'm aware of that has high resolution graphs on the console is the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-WS-1200-IP-OBSERVER-Solar-Powered-Wireless-Internet-Remote-Monitoring-Weather-Station/dp/B00O9ZR6K4/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather WS-1200-IP OBSERVER Solar Powered Wireless Internet Remote Monitoring Weather Station</a>.

If there is a feature that stands out on both the WS-11 and WS-110 it is the ability to set an alarm based on temperature or humidity.  There is some limitations on this, you can only use the first external sensor for alarms.  Still, this opens up many uses, especially for improving your energy efficiency.  For example you might use such alarms to be more systematic about using room air conditioners or space heaters.  You can also set alarms based on time, humidity, dew point, and on the WS-11: barometric pressure.  The alarm is loud enough to be heard in a room and adjacent rooms.  However, you might not hear it if you are too far away, so it won't serve as a "whole house notification."  Should you miss an alarm, there is an icon on the console indicating that an alarm has gone off.

The alarm feature is as good an example to point out the general downside of this type of electronic device.  There are only 4 push-buttons to access every feature and the user-interface is terse and arbitrary.  For example, there is not a consistent button to confirm a selection nor is there any uniform way to exit a mode.  On a device with so much capability, the setup mode is a long sequence of options.  The second clip in the video cycles through all the configuration options.  In the case of the alarm setup mode, you can either wait 30 seconds and it will automatically return to the normal running mode, or if you want to immediately return to the running mode, you'll have to cycle through all the possible parameters that can be alarmed in order to get out.  Some attempt has been made to reuse buttons in an intuitive way, but these 4 buttons are seriously overloaded with functionality.  Basically you'll have to either memorize an operation or go back to the manual.  The vast majority of electronic devices have user-interfaces with a few overloaded buttons, so it is hardly a surprise.  Nonetheless following the status quo is a burden on WS-11 and WS-110 users, and the awkward user-inferface may discourage you from getting the most value from either the WS-11 or WS-110.

In summary, the WS-11 and WS-110 are definitely niche products.  They should be purchased because you really want the particular collection of features they have.  Ambient Weather alone has a wide line up of similar devices, so you should make your selection based on your true needs and interests.  If your main goal is simply monitoring temperature, the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-WS-07-Big-Digit-8-Channel-Wireless-Thermo-Hygrometer/dp/B00BWUOVE8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather WS-07 Big Digit 8-Channel Wireless Thermo-Hygrometer</a>&nbsp;is simple and easy to read.  If you desire having the highs and lows displayed, then the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-WS-08-X2-Wireless-Indoor-Outdoor-8-Channel-Thermo-Hygrometer-with-Daily-Min-Max-Display-with-Two-Remote-Sensors/dp/B00EW463SS/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather WS-08-X2 Wireless Indoor/Outdoor 8-Channel Thermo-Hygrometer with Daily Min/Max Display with Two Remote Sensors</a>&nbsp;might serve your needs.  If you desire additional meteorological data like barometric pressure and forecasts based on pressure, perhaps you should consider the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-WS-1171A-Wireless-Advanced-Weather-Station-with-Temperature-Dew-Point-Barometer-and-Humidity/dp/B003OSSH9G/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather WS-1171A Wireless Advanced Weather Station with Temperature, Dew Point, Barometer and Humidity</a>.  If you have a greater interest in astronomical matters, perhaps the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-WS-1173A-Wireless-Advanced-Weather-Station-with-Temperature-Dew-Point-and-Barometer/dp/B00BQFWYF2/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather WS-1173A Wireless Advanced Weather Station with Temperature, Dew Point and Barometer</a>&nbsp;would be a better match.  If you are really interested in monitoring your overall weather conditions, perhaps you spend a little more and get a complete weather station like the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-WS-2080-Wireless-Home-Weather-Station/dp/B003OSJ08S/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather WS-2080 Wireless Home Weather Station</a>.  For that extra cost you get an automated rain gauge, anemometer, and the potential to connect your station to your computer if your interests further grow.  For a modest additional investment, you would end up with a complete weather condition monitoring system that is expandable.  Nonetheless, the WS-11 and WS-110 do have their place.  Either model could be extremely helpful in making your living space more comfortable while lowering your energy costs.
