ThermoPro TP-59 Indoor Temperature and Humidity Monitor Review

Having an indoor temperature and humidity monitor in your home is a popular choice. You can choose the old analog standalone temperature gauge and humidity sensor, but these are much less popular these days after the development of highly accurate digital units.

And today many monitors have handy additional features that make them even more useful and attractive to users. Features can include things like temperature and humidity monitoring and alarms, backlights, Fahrenheit to Celsius selection, touch screens, remote sensors, etc.

There are many reasons why you might want a temperature and humidity monitor in your home, including monitoring the conditions in:

• critical environments, such as greenhouses, wine cellars, animal enclosures, music rooms
• various spaces in your house, like the basement, attic, garage, or your baby’s bedroom
• areas of concern, such as monitoring for excess moisture in various locations throughout your house
• various locations throughout your home, simply because you can and you’re curious.

And the ThermoPro TP-59 can do all of this and more. See our review of the best and not-so-good points below.

TP-59 Unboxing – What’s in the Box?

On receiving the TP-59, I was a little surprised by how small the box was. It only measured approx. 4.5” x 3.5” x 1.25” / 12cm x 9cm x 3cm. This isn’t good or bad… I just thought the packaging would be bigger.

Inside the box is the unit itself (bubble-wrapped) plus 2 x AAA batteries and instruction booklet.

TP-59 Specifications

Here are the stated specifications of the TP-59:

• Bluetooth range = 260ft / 80m
• Temp range = -4°F ⇨ 140°F / -20°C ⇨ 60°C
• Temp accuracy = ± 0.5°F
• Humidity range = 10-99%
• Humidity accuracy = ± 2% relative humidity

The unit itself measures approx. 3.25″ x 4.1″ x 0.8″ / 82mm x 104mm x 21mm (WxLxH).

Using the TP-59

The TP-59 indoor hygrometer and thermometer was very easy to start up. You simply installed the 2 supplied AAA batteries and it started automatically. There is no on/off switch, so the unit stays on 24/7 (unless you take out the batteries)

On the Front

On the screen it displays the following:

• Humidity (%), plus high/low humidity for the last 24hrs and humidity trend direction
• Temperature (°F / °C) plus high/low temperature for the last 24hrs and temperature trend direction
• Comfort level (Dry, Comfort, Wet)
• Bluetooth connection
• Low battery indicator

The Comfort Levels are defined as when the humidity levels are:

• 10-30% = Dry
• 31-60% = Comfortable
• 61-99% = Wet

There are very few buttons to change settings on the unit itself… only:

• °F / °C selection
• Bluetooth
• Back light
• Clear high/low temp/humidity

The only things to really select in normal operation are the °F / °C selection (once that is set to your preference, you probably won’t change it), and the back light. You may also want to use the clear high/low temp/humidity button to reset these readings.

The back light works ok. The grey LCD digits stand out well against the orange backlit background.

On the Back

On the back of the TP-59, you have:

• Access to install the batteries
• The desktop stand allows it to stand upright on a flat surface
• Rubber pads for grip so that the unit will not slide when laid on an uneven surface
• A hole for wall mounting the unit
• A magnet to make the unit stick to metal (eg. you may want to stick it on the fridge or magnetic whiteboard)

Installing/Using the App

I use an Android phone, so all comments relate to the Android version of the App.

Installing the App was easy. There is a QR code on the box and inside the instruction booklet. If your phone does not scan QR codes, then you can go to the App Store and search on “ThermoPro Sensor”.

The App does not have many downloads/installs. It also does not have the best feedback rating, so I was a bit dubious when I downloaded and installed it. However, once installed, it is pretty easy to use.

Once you install the App, you have to connect the phone to the TP-59 via Bluetooth. If the Bluetooth icon is not visible on the TP-59, you have to press and hold the Bluetooth button on the unit to enable pairing. Once you enable Bluetooth on your phone, they should connect. The whole process was a bit clunky, but with a little perseverance, it was ok. Just follow the steps in the booklet.

Once connected and you are using the App, there are not many settings to play with within the App. You can rename the device, set high/low alarm setting levels, and switch between °F / °C. You can also connect multiple devices and select the one that you want to view the stats for (ie. You can place multiple remote units in various locations around your house).

When viewing the stats for a particular remote unit, you can view:

• the temperature in °F / °C
• humidity
• historical charts of temperature and humidity for the last 24hours, 1 week or 1 year.

There is a minimal (a few seconds) delay between temperature/humidity updates on the device and the corresponding update on the App.

I noticed via the App that the device was trying to do a Firmware update which tried and failed quite a few times. After a few hours, it succeeded, so not sure why it wasn’t successful the 1^st time.

I also noticed that the App seemed to lose the connection to the device. The temperature and humidity readings would still update, but the graphs would not update. After closing the App and restarting it, the charts started working ok again.

Overall, in my opinion, the App is a bit clunky. However, it is not needed to operate the unit itself, so you may not want to install / use it. It is needed to remotely monitor the unit and to track the historic temperature and humidity levels (for up to 1 year). It may be handy if you have a few units around your home or out in the garage / basement / greenhouse, and you want to monitor multiple regions from one point. So, it’s up to you whether to use it or not.

Overall Opinion of the TP-59 Indoor Temperature and Humidity Monitor

The ThermoPro TP-59 indoor temperature and humidity monitor was easy to set up and use.

The unit is very easy to use. With few options to play with, you can’t get into trouble. Its display is excellent with big numbers to make reading easy at an angle or distance. The screen is reflective which does distract slightly as you can see reflections in the screen. The display is monochrome which is a little boring, but works well with the back light active.

The App, in my opinion, was a little clunky to use but tells you everything you need to know. I am not a fan of Bluetooth connections… The App will only work when your phone is connected via Bluetooth to the unit. Personally, I would prefer a WiFi connection so that you can read the measurements wherever you have an internet connection, instead of having to rely on a direct Bluetooth connection.

Conclusion

If you are after a simple-to-use indoor temperature and humidity monitor, then the ThermoPro TP-59 is a good solid performer. It does not have all the bells and whistles of some of the other higher-priced indoor hygrometer and thermometer competitors, but it does the job well and tells you what you need to know.
