SwitchBot Indoor (Editor’s Choice)

This device’s fantastic 120m Bluetooth range means you can operate it from your smartphone virtually anywhere in your home. Thanks to this impressive length, it could be ideal for use in your garden to monitor things like the greenhouse’s temperature.

The SwitchBot Room Thermometer accurately measures humidity and temperature and has a whopping 36 days of local data storage. Additionally, you can store unlimited readings if you export the info to the partner app.

It has a simple and functional design and can be placed free-standing or wall-mounted. The high-quality LCD display gives it superior visibility, which is also boosted by the large display font.

Govee WiFi (Luxury Choice)

If you want advanced functionality and readings, this product’s WiFi connectivity and its partner app are brilliant. Pair the device with your smartphone using the high-speed WiFi connection, and then get a myriad of data, graphs, and features via a designated app.

This includes the ability to export data in CSV format to a computer, and it stores up to two years’ worth of stats. The Govee WiFi Room Thermometer is a great product for those who want to integrate it with a smart home system or play with the figures.

It is highly accurate and can measure temperature with tolerance up to ±0.54 degrees Fahrenheit or ±0.3 degrees Celsius. You can see various functions, too, like preset temp and humidity ranges that trigger app alerts.

ThermoPro TP49 (Best Value)

This handheld unit uses just one AAA battery for operation. It has a low power consumption rating, so one battery should last for a long time. It also refreshes every ten seconds to provide accurate readings.

The ThermoPro TP49 Digital Room Thermometer is a compact model that features a simple emoji system to denote comfort level in the room. Therefore, you can see at a glance if your house is too dry or wet or if the temperature needs adjusting.

It measures temperature and humidity with a large range. This includes temperatures between -50 to 70 degrees Celsius and 10 to 99% relative humidity. The LCD screen is large for convenient use, and the readings are displayed in a clear, bold, digital font. Lastly, depending on your preference, you can switch the units from Celsius to Fahrenheit.

NOKLEAD Hygrometer (Best Easy to Read)

You will love the colour-coded bar included in this product’s display if you want a clear visual indicator of your home’s comfort level. It sits in the middle of the screen and ranges from dry to wet. You can quickly see if your room temperature or humidity levels need adjusting.

The NOKLEAD Hygrometer is great for desktop use and is highly portable. It is free-standing, and you simply fold out a stand at the rear. Alternatively, the back has sticky pads. Thus, it can be wall-mounted in a greenhouse or garden shed.

The temperature and humidity readings are highly accurate and can measure ranges of 14.2-140-degrees Fahrenheit and 10-95% humidity. In terms of tolerance, it has an accuracy range of ±1 degree Celsius and ±3% humidity, respectively.

Beurer HM16 (Best for Accuracy)

The emoticon key of this device allows you to monitor comfort levels in your home or office to improve your quality of life. It shows a simple set of different smiley face emojis. Each has a different meaning and relates to an ideal, dry, or humid condition.

The Beurer HM16 Room Thermometer is highly accurate, too and has measuring ranges for temperature and humidity of 0 to 50 degrees Celsius and 20% to 95%, respectively. We like that the unit of measure can be switched from Celsius to Fahrenheit.

For easy installation, this device can be free-standing using the fold-out support. Alternatively, it has a hanging insert for wall mounting. In terms of power, it runs on just 1x CR2025 battery, which is included.

ORIA Wireless (Best Design)

This handy two-pack is a solid choice if you want a pair of devices to monitor the temp in multiple rooms. The products are relatively small and can be placed out of sight virtually anywhere. Moreover, they both have a ranging loop at the top, so you can thread them through items for security.

The ORIA Wireless Thermometer has a highly accurate MEMS sensor and can read both the temperature and humidity. It operates with a small margin for error, including ±0.5 for temperature and ±5% for humidity. Combine this with real-time updates, and you have a reliable gadget.

To get readings, it has Bluetooth connectivity, and you can download the accompanying app. This allows you to get immediate notifications, but there is also a smart notification system. Here you set reminders, and it will ping an alert when the temperature or humidity reaches a specific value.

Aycorn Digital (Best for Kids)

If you have newborn or young children and need reliable room and bath temperature readings, this device is perfect and fun. It is completely waterproof and will also float on the water’s surface to ensure your kids’ safety during bath time.

Thanks to the bright crab design, your little ones will enjoy it and could use it as a toy, too. Aside from this, it is still highly accurate and has some safety features. For example, if the reading is above 39 degrees Celsius, a red LED light will flash, and a message will appear on the screen.

Easy to use,  you can get temperature readings within one second with this Aycorn Digital Bath and Room Thermometer. You should be able to assess the screen quickly, too, as it has a large font. If you do want to operate it in a bedroom, it has two feet and can be placed free-standing.

How to Choose a Room Thermometer

As you can see, there is a brilliant range of different room thermometers, so you may struggle to know which one to choose. First, think about where you want to use it and who it’s for. Next, check out the four important factors listed below in our simple buying guide.

Functions

Firstly, what functionality does the device have? As a bare minimum, it should provide a temperature reading in both Fahrenheit and Celsius. Many products like these, however, also act as a hygrometer and offer other text like humidity, date, time, and a comfort level indicator.

Aside from the simple functions, look at what you can do with each setting and how much data is available. For example, some items can store historical info, while others provide enhanced usability through graphs and charts.

Connectivity

Secondly, can you connect to the room thermometer? Some monitors only display capabilities, and you have to control and view them using the built-in screen.

However, others have Bluetooth and/or WiFi connections, so you can pair them with an external device like a smartphone or tablet. These products have greater flexibility and often include a free-to-download app with advanced features. Usually, you can operate the program and change settings without touching the room thermometer. Consider if something like this would be useful or if you only require a static device.

Power

You should also look at how the room thermometer is powered, which could affect where and how you use it. 

Battery-powered devices give greater flexibility and allow you to use them easily in different rooms or take them on holiday. However, there is the increased cost of continually buying new units.

In contrast, mains-powered models can function continuously, but you are limited to where there are electrical sockets.

Design

Lastly, we advise considering the design and style of the room thermometer. For example, you may prefer a particular colour, shape, or model. Usually, these devices are functional and do not particularly stand out, but there are also units suitable for children, and some are available in different colours.

The display plays a significant part in the overall design too. LCD screens are usually the best quality and offer the clearest readings. Don’t forget to also look for features like a backlight, which can help improve visibility in the dark.

Summary

Our top pick is the SwitchBot Indoor Room Thermometer due to its fantastic connectivity, high-quality display, and smart features. This compact device has a simple but elegant white casing and can easily fit on a shelf, coffee table, or bedside cabinet. To control it, you can connect via Bluetooth and download the SwitchBot app for your smartphone. It has a brilliant range of up to 120 metres, and you get a notification if you go beyond this area. In terms of functionality, it is highly accurate and can measure temperature and humidity. It also refreshes every four seconds.
