Using a Wi-Fi connection, as opposed to Bluetooth, this makes the Temp Stick more reliable than the average temperature monitor. The use of Wi-Fi also makes it possible to connect to the device and monitor temperatures remotely, whereas a Bluetooth connection requires relatively close proximity to the device itself. With the Temp Stick, setup is as simple and straightforward as it could possibly be, and once it’s set up, the device is exceptionally simple to use. You can even set up a mobile hotspot with the device, which is perfect if you need to use it while on the road.
The Temp Stick Wi-Fi thermometer is advertised as being easy to set up in just three minutes, a metric that it more than lives up to. It usually takes even less time than this to get going with the Temp Stick. The device comes factory calibrated, but users have the option of making adjustments to the calibration as they see fit. This is a useful feature if you have other devices in your home and you want to synchronize them.
Any wireless temperature monitor that you use is only going to be as useful as the app that allows you to view and monitor the data. If the app is awkward to use, or the visualizations unclear, it isn’t going to be of much use to you. Whether you are an iOS or Android user, the accompanying app is simple and straightforward. It also allows you to access the entire history of archived data from the device. However, even if you don’t own a smartphone, you can use a laptop or computer to access a web-based interface for your device.
Battery Level and Connection Loss Alerts
One of the most useful features of the Temp Stick is the ability to set up automatic alerts whenever the battery level dips below a certain level, or the device loses Wi-Fi connection. This is an often-overlooked feature that other remote temperature monitors lack; it is an essential feature for the most important applications, those where temperature fluctuations need to be responded to as quickly as possible. The Temp Stick takes readings as every five minutes, although you have the option of setting a longer interval if you wish. If the Temp Stick misses a reading, because of power or connectivity issues, an alert is automatically sent. The Temp Stick will continue to monitor and log temperature, making up to 100 entries, until it can connect and upload the data again.
Adjusting Recording Intervals
The ability to adjust recording intervals is great for extending the battery life of the Temp Stick. It provides options to record the temperature at 5, 10, 15, 30, or 60-minute intervals. Unfortunately, this means that true real-time temperature monitoring is impossible with this device, however, the five-minute interval time should suffice for most people’s usage. One thing to note is that the first two readings the device takes will be one hour apart; after the second initial reading has been taken, the device will begin recording according to your preferred time interval.
With any remote temperature monitor, you want to be sure that the readings being taken are as accurate as possible. Fortunately, with the Temp Stick you don’t have to worry about this side of things. The Temp Stick is designed to operate in commercial freezer environments, where accuracy and reliability are of paramount importance. As a result, it is one of the most reliable and robust devices straight out of the box. The Temp Stick also has a comfortingly wide operating temperature range, performing without any issues at temperatures between -40 F up to 125 F. It can also handle any level of humidity (0 – 100%).
No Subscription Fees
This is a crucial selling point for many people. Remote temperature monitors used to require some form of monthly subscription, something which pushed them over the boundaries of affordability for many users. With the Temp Stick, there are no hidden costs or fees for you to worry about; once you have paid for the device, that’s all the money you need to spend. You might pay more upfront for the Temp Stick compared to other remote temperature sensors, but you definitely get what you pay for.

Additional Thoughts on Temperature Sensors
Ensuring a stable temperature is critical if you are storing old and fragile materials, or if you have plants and animals in your home that require a particular constant temperature. Many people use temperature monitors to ensure that musical instruments such as guitars are kept at an optimum temperature, preventing them from slipping out of tune due to temperature fluctuations.
These devices connect to a Wi-Fi, cellular, or Bluetooth network to allow them to communicate with smartphones and the corresponding app. With this connectivity, constant monitoring becomes simple and straightforward, whether you choose to use your smartphone, tablet, or laptop or computer to monitor the data.
In the past, these devices have been bulky, unwieldy, and most importantly, expensive. In fact, many of these devices used to require the users to pay excessive monthly subscription fees. By contrast, the newer generations of these devices are small, portable, and much more affordable than they used to be. The older generations of devices were only suitable for professional usage, or a narrow range of specialist home users. Now, these are devices that the average person can easily afford to purchase and install wherever they are needed in the home.
There’s a variety of different manufacturers operating in this space today, producing devices that can appear to be largely similar from the outside, but which in fact differ from one another in several key ways. For this article, we have taken a look at a number of the different options out there for consumers who need a wireless temperature monitor, and come up with a list of five of the best devices everywhere. These devices all combine affordability and functionality, and represent the best value for consumers today.
Factors to Consider When Buying a Remote Temperature Monitor
Any of the devices listed above can provide reliable remote temperature monitoring (also known as WiFi thermometers), but the right device for you will depend on your individual circumstances and needs. Note, if you are interested in an indoor thermometer feel free to read our guide on indoor outdoor thermometers, we have a detailed breakdown for you. For this reason, it is important to carefully investigate any device that you are considering buying so you can be certain that it will do everything you need it to. The following are the most important factors to consider when choosing a remote temperature monitor (also known as wireless thermometers or WiFi thermometers):
Your size requirements will depend upon where you are planning to install the device. For example, if you just need a device to monitor the temperature of a whole room, you can often get away with installing a relatively large device without it being intrusive. However, if you want to monitor the temperature of an instrument from within its case, for example, you will need a smaller unit.
Many of the larger temperature monitors allow or require the use of an AC power supply. On the other hand, smaller units tend to be battery powered. Of course, with batteries that can last a year or more, this isn’t an issue for many people.
The type of connectivity you should aim for will depend on a variety of factors. Wi-Fi connected devices will offer the greatest range, and allow you to access the devices and their data remotely/ Devices that use cellular data also offer this feature, but they will require additional subscription fees, and will only operate in areas where there is a cellular data signal. Bluetooth devices are short range, and their ideal range will be reduced by any physical obstacles such as walls and furniture.
Some devices also use a proprietary wireless signal to communicate between devices and sensors. Both Bluetooth and proprietary connections are best suited for situations where you only need to monitor temperatures within a single location and don’t require remote access to data.
Some remote temperature monitors are best at recording temperature logs, but offer little in the way of alerts to temperature fluctuations. This is fine for many people’s setups, especially where the devices are only being used in the home. However, where the need to keep a constant temperature is more important, and any changes to the temperature need to be addressed straight away, you should look for a device that offers SMS or email alerts.
Home or Business
While remote temperature monitors are generally not marketed specifically towards businesses or individuals, it stands to reason that the more accurate devices would be better suited for business use. For example, if you are monitoring the temperature of a walk-in freezer for your business, the stakes are much higher than they are for your garden greenhouse. Make sure that any temperature sensor you buy offers an appropriate level of accuracy and a suitable range of operating temperatures.
The devices on this list represent the best temperature monitors available for the average user. Whether you need to monitor your home or place of work, a remote temperature sensor offers a convenient and reliable way of ensuring opti
