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.

This product is very popular due to the simplicity of the setup process; however it may need some tweaking to get accurate readings.

The main downside of this device is that the outdoor thermometer is operated only by batteries.  This device provides indoor and outdoor humidity and temperature readings, moon phase, forecast and barometric pressure. The console displays high and low readings and the time and date, but it cannot set alerts or connect to the internet.

This unit is brilliant and offers a lot of good features which make it the perfect choice if you have a low budget.

The WS-10-X4 comes with four sensors but another four sensors can be purchased as required. There is also an integrated sensor located inside the display console.

Unlike the other Ambient Weather in the top 5 list, both the sensors and the base unit all run on batteries only. However, many customers have reported that their batteries can last months at a time.

The main console has the ability to enable you to set alerts when the humidity or temperature reaches a certain level. It also displays minimum and maximum readings for each of the sensors you have connected. The main features of this thermometer are temperature and humidity readings. This thermometer does not collect enough information to give forecasts.

This is a brilliant value for money choice, but it doesn’t offer the full-range of readings that some of their other models offer.


  • Connect up to eight sensors
  • Alerts that notify you of temperature changes
  • Sensor available for the pool (additional cost)
  • Humidity and temperature displayed on base unit and remote sensors

  • Display can be wall mounted
  • Backlight is adjustable

La Crosse Technology V10-Wth-Int

This is another brilliant indoor outdoor thermometer from La Crosse technology.  This indoor outdoor thermometer performs perfectly for the amount of money it costs.

The main feature of the V10-Wth-Int is that it uses the La Crosse app which offers remote reporting. This app enables you to track and view weather conditions, receive push notifications and set alerts conveniently using your smart phone, tablet or computer.

The Differences Between a Home Weather Station and an Indoor Outdoor Thermometer

Although many people believe that home weather stations and indoor outdoor thermometers are the same things, there is a huge difference between them. So that you cannot be mistaken, we will talk you through some of the main differences.

Indoor outdoor thermometers are brilliant devices that measure the humidity and temperature both inside and outside. Most of these devices have a display screen that will also tell you the correct time and date. Some of the more expensive indoor outdoor thermometers may also show barometric pressure and forecast the weather but this is their limit.

Home weather systems have even more functions than this. They offer a more thorough report of the conditions in the local area and can also show you things such as wind direction and speed, UV, rainfall, solar radiation, heat index, dew point and wind chill.

To make home weather systems even more exciting, they are able to connect to the internet and to your smart home devices. This enables you to view historical and real-time conditions at any time, wherever you are by connecting to your phone, tablet or computer. These weather systems also pair with Amazon Alexa and Google Assist, which means you can ask them to let you know the current conditions both indoors and outdoors. They will then give you your very own weather report of exactly what it is like. They also have IFTTT compatibility which enables you to control your other smart devices with automatic triggers.

As you may have guessed, weather stations tend to cost more money than a standard indoor outdoor thermometer due to their functionality. However, if having a device that shows you reliable local weather conditions is important to you, then buying a home weather station is a necessity. We think that having a device that provides you with rainfall and wind speed readings as well as humidity and temperature is the best solution for a full view of the weather in the local vicinity.

Things to Think About

Choosing the correct thermometer for you may seem impossible. Let’s think about the factors to consider before buying your thermometer:

Readings included – you need to think about what is important. The basics include temperature and humidity, forecast, barometric pressure, date and time, high and low pressures. Other features you may find useful are rainfall data and wind direction and speed.

Accuracy – This is the most important thing to think about when buying your thermometer. An accuracy range for temperature of + or - 2ﹾF and for humidity of + or – 5% is usually acceptable.

Sensor placement – Outdoor sensors need to be shaded and not on a surface that radiates heat. If you are struggling to find a place, think about purchasing a radiating shield.

Smart home integration – For people who own a smart device, adding a weather station that connects to these is a great idea. You will be able to control your other smart devices depending on the weather.

Remote reporting and monitoring – you will need a Wi-Fi enabled device if you want to view your weather data on your phone or other devices.

Display – This is the main screen, so you need to pick something that is simple to use and high-quality. Think about how the screen is powered. The best are the ones that are connected to mains power. You also need to think about how many sensors you require.

Price – you could buy a cheaper thermometer that offers a few accurate readings or a more expensive weather system that has many features. It all depends on your budget and what you are looking for.

It is quick and easy to get accurate readings with a good-quality thermometer. Purchasing an indoor outdoor thermometer that has an internet connection can give you accurate readings when you’re away from home.

Choosing the correct thermometer for you may seem like a hard task, which is why we’ve helped you out by giving you our top 5 thermometers for 2018. Our number one model may not be the cheapest, but it certainly offers value for money.
