Ambient Weather WS-2902 Osprey Wi-Fi 10-in-1 (Best Overall)

The Ambient Weather WS-2907 came out as the favorite for many reasons including its price and capabilities. The wireless outdoor sensor is powered by a solar panel (there is also a battery compartment that is used as a backup just in case the solar panel stops working). This brilliant system works 24/7 to give you the most accurate measurements.

Every 16 seconds the wireless outdoor sensor sends information to your indoor display. Your indoor display can be placed anywhere indoors as long as it is within a maximum of 330ft of your wireless outdoor device, or 100ft if there are lots of walls in the way. The indoor display is powered by a wall adapter.

The Ambient Weather WS-2902 has a lot of basic features that you would expect, including:

  • Measures barometric pressure
  • Measures the indoor and outdoor humidity and temperature
  • Forecast
  • High and low temperature readings
  • Date and time on the main display

In addition to the features above, it also has some more advanced features which makes it even more versatile. These include:

  • Rainfall measurement
  • Wind direction and speed
  • UV and solar radiation
  • Heat Index
  • Dew Point
  • Alerts for all parameters
  • High and low readings
  • Smart Home integration
  • Remote reporting and monitoring

This weather system provides the full experience. It offers an amazing level of functionality which compared to its relatively low price, makes it value for money. This is why this is our number one indoor outdoor thermometer for 2018.

Some of the interesting features of this device have been explained in more detail below:

Accuracy – The Ambient Weather products are well-known for the accuracy they provide their customers. This latest weather system (the WS-2902) is no exception to the rule. This is currently the most accurate device on the market. It has an outdoor temperature range of between -40ﹾF and 149ﹾF. The indoor temperature range is between 14ﹾF and 140ﹾF. The temperature accuracy is + or - 2ﹾF which is very small compared to lots of other devices. It offers an indoor and outdoor humidity range of between 10 and 99% and has a humidity accuracy of + or – 5%. This weather station will always give you an accurate report which is always available right at your fingertips.

Smart-Home Integration – This weather system can connect to your smart home software such as Amazon Alexa. This will then enable you to ask your home system for an accurate, up to date report on the weather. This product gets even better; once you have discovered the weather report you can then control other external smart-home devices such as blinds, sprinklers, switches and lights.

Wi-Fi connected for reporting and monitoring remotely – The Wi-Fi enables your device to connect to the Ambient Weather Network or to Weather Underground. These sites use details from lots of thermometers to build up a full-picture of the conditions in your local area. It enables you to look at the historical data and create alerts, all of which can be done from your phone, tablet or computer.
