WiFi Temperature Sensor Smart Thermometer: Digital Temperature Monitor Gauge with Waterproof External Probe, App Alert & Buzzer Alarm, Rechargeable Battery, for Freezer, Refrigerator, Fish Tank

A great product. I stuck the sensor on the copper hot water tank and I can see when we have hot water and when we need to switch on the emersion heater.

I'll start this review with a warning: I am a geek and don't apologise for that. We have recently moved house and have an air source heat pump and sometimes the hot water seems tepid instead of hot. I wanted some way to monitor the water temperature in the hot water tank 24/7 and this promised to do exactly that. The setup was easy: install an app, pair the device with your phone, connect to the home WiFi and it was working. I installed it in a stat pocket in the tank (designed for this exact purpose) and it all works. The probe goes into the pocket and the meter attaches to the tank magnetically. It has a very obvious and bright red display (no problem for me as my water tank is in the garage but if this were in my bedroom at night it would drive me mad). It all couples to the Tuya IoT platform so I can actually monitor it myself and control other parts of the system based on its output.

I've set this up with a cheap portable sim modem to monitor and alarm if the temperature in my motorhome goes too high or low for my dog. It's great and reliable.

I brought this as I wanted to remotely monitor the temperature of my hot water tank. Easy to install, worked first time and temperature seems to be reasonably accurate. Paired it with “Smart Life” app and now I can see the tank temperature remotely. Important note, that this unit does require an external power supply for continuous operation.

Not bad little device, I use it now to measure the top of my hot water cylinder. Handy because I can instantly see how much HW we have on my phone. App is a bit clunky but works. Be warned though, this does not last long after a charge so you have to leave it plugged in to a USB. So not much good if you haven’t a socket nearby.

I’ve read the reviews of this sensor and they don’t make sense. The only way you can measure the accuracy of water temperature of a water tank is if the pro is actually touching the water. If you put this against your hot water tank, it’s probably going to be 20 to 25° below what the water actually is in the tank. I’m certain that this item is not being advertise correctly it is no good for measuring hot water in a tank If it cannot touch the water. It doesn’t matter whether you push it through the insulation on the outside of the tank it’s not going to Work.

I liked that is small, with a bit of autonomy/battery, but after about 3 weeks it started going offline every now and then. Now is completely offline and I doesn't want return. Unfortunately the unit is in another country and I can't return it.

I needed to remotely monitor the central heating flow temperature of a communal heating system and this product fulfilled all my requirements perfectly. It was extremely accurate and matched the controller temperature measurement without any need to offset the temperature in the app. It connected easily to a distant WiFi router and has so far not lost the signal. It connected seamlessly to the Smart Life app I already had on my phone. Not sure if it's a function of the temp sensor or the app but it it displays a very useful temperature/time graph. I would highly recommend this product.

Bought to give warning when wood burner water temperature gets too high and it works pretty well with the temperature probe clamped to the burner water outlet. The probe cable is a bit short so the device is quite close to the hot wood burner but so far it hasn’t melted. Would be nice if a probe cable extension was available but so far I haven’t found one. Would also be nicer if there was a physical button on the device or a way via the app to acknowledge the alert.
