ThermoPro TP351 Bluetooth Hygrometer Thermometer for House, 80M Temperature and Humidity Monitor, Remote App Control Humidity Temperature Sensor, 2-Year Data Storage Export for Greenhouse Room Home

I needed to monitor temperatures in an outdoor hutch for guinea pigs. This has proved ideal. Given the price, I thought that it was worth a try especially as other temperature monitors cost several times more. It is definitely worth a try - and there will be another one of these monitors in our greenhouse very soon.

Perfect for what I needed. I have solar thermal that heats the water tank - never sure how hot the water is in the morning (and if it needs a boost) - placed this inside the hot water tank jacket to give me a rough idea - works perfectly.

The functionality this device provides is brilliant.I’d give it five stars if: It was waterproof. This would make is massively better than any competitor.The other slight niggle is the range. The product description really highlights its long range BUT this is a bit misleading. I suspect its correct in clear line of sight but not if walls or vehicles are involved.

Can lay in bed now and see what temp we have in the greenhouse down the garden. I really like this device so bought two more, one each for the polytunnel and greenhouse on my allotment.

A clever accurate gadget for tracking external temperature.

If you need a little extra then this is pretty good, especially for the price. You can get a set of thermometers/humidifier sensors for around the same cost with a display and what not. So this has to offer more to be worth it.And the app is a really good addition. Sure, it’s not something everyone will use and if not this isn’t ideal, but if you do then it’s a game changer. The range is very good for this.In terms of accuracy we have found that it measures both temperature and humidity really well. All our devices show very slightly different values but all close enough to be accurate enough. This is in with them so we’d say it’s accurate. You can export the data from this, which is probably a specific use case and works fine.Overall it’s a very good device if you need the features. We’re happy with it.

This is exactly what I was after. I've already got a couple of other temperature/humidity monitoring devices from this same brand but they're the ones with the screens on them. I wanted something to go inside a storage cupboard that we don't open very often so didn't need a screen, and this little device fits the bill perfectly. Looking in the app on my phone, it shows the temperature and humidity to be exactly the same as what I'm seeing from the other 2 devices with the screens when I've left them all side-by-side for a while. It's surprisingly small and compact, the wrist strap that's attached to it has proven very useful for hanging it up from a clothes rail inside the cupboard (I thought it would be better to have it hanging in free air rather than sitting flat on a surface somewhere), it comes with batteries, it was a doddle to set up in the app, Bluetooth range is decent enough to be connected from several rooms away, and overall I am extremely pleased with the product. I've come to trust this brand now as I've been using their monitors for a few years and have experienced zero issues with the hardware or the app.

CONS-Fahrenheit only, how odd. There is nothing in the manual about changing to celsius, nor can I find a setting when I search around. Not so great for a device being sold in Europe (which has a CE mark on the enclosure).-uses replaceable AAA batteries (a set of low-end batteries are included). Better to have an internal rechargeable battery-indoors only-yet another appPROS-connected via bluetooth right away (after downloading app and adding device)-app has two useful screens (temp and humidity), and you can track both via the hour, day, week, month, or yearNOTES-I am not familiar with Fahrenheit, so I’m going to have to think twice about actually using this (a quick glance and seeing that the temperature is 70 would mean deathly hot, not comfortably warm). I’m not willing to have to faff with a chart to see what the temperature is in Celsius.
