Wifi Tuya Smart Temperature and Humidity Sensor, Smart Hygrometer Thermometer for Alert, No Hub Required, Compatible with Alexa and Google Home, for Home, Baby, Garages, Intelligent Linkage

Although we have thermostats upstairs and downstairs for our central heating, these don’t let us know individual room temperatures which can vary hugely from room to room. I bought a three pack of these little beauties for just over £20 which is far less than other comparable units.They are tiny, about 4cm by 1cm by 1cm, and wherever you choose to place them, they’re inconspicuous. The boxes contain a unit, instructions and a resetting pin (think iPhone). You will have to provide the two AAA batteries per unit.Once you have the Tuya App (use your phone camera to read the Q code in the instructions), it’s really straightforward to set up: with batteries in place, use the reset pin to set the device to blinking (pairing mode), then just follow the Tuya App instructions! (Choose the “+” to add, choose “sensor” then, in my case, “Wi-Fi” and you’re good to go! I renamed mine to fit the rooms in which they were placed.As I have Alexa, I also added them to my Alexa devices.All three units connected easily and on my first attempt.The temperature reading updates each hour, which is fine for me as I don’t expect sudden variations. You can set parameters outside of which you will get a notice and if you have Tuya (or compatible) aircon, you can set up ITTT operations.All in all, I’m really pleased with these units and will now be able to monitor individual room temperatures when I’m away from home.

UPDATED DEC 2024The remaining two sensors have gone the same way as the first one. So all ended up in the recycling bin, poor quality. Bought ThermoPro to replace these and no issues, so much better.Original Review - July 2024One of the three devices failed after a few months. Even with new batteries it will not install on the Smart Life app. It pairs WiFi wise to 2.4Ghz but will not install. Disappointing and will not but again. The other two are are still working but be aware they do NOT update the app that quickly. About once per hour so no use for anything where you may want near real time information on temperature or humidity.

Devices work as expected, app can be a bit sluggish to update data (can take 2 to 3 refreshes to actually get the current temp shown on the summary page). Can be linked to other smart home apps to get readings into other screens (Google Home)

I’ve been pleased with this product. I am using them in my house to monitor temperature and humidity levels in various rooms. Tested against other thermometers, I have found the temperature and humidity to be accurate. They were easy to set up (I already use smartlife) and linked up first attempt (via mobile broadband connection). I am replacing my first set of batteries after 4 months which I am happy with. Good value for money.

Easy to set up and they work with reasonable accuracy. You can change the name of each device in the 'Smart Life' app so that you know which location you are 'reading'.Deduct 2 stars because I can't work out how to link it to Alexa to "ALERT" me to temperature/humidity changes. The listing says: "SMART HYGROMETER THERMOMETER FOR ALERT, COMPATIBLE WITH ALEXA, INTELLIGENT LINKAGE". That sounds exactly what I wanted but.....I failed to find any way to get an "ALERT" via the "INTELLIGENT LINKAGE" to "ALEXA" and I failed to find any way to automate a fan or heater via "ALEXA" - which is what I wanted. Either I have failed to understand how to get an "ALERT" or the listing is misleading.The app does allow you to set up alarms via the app but the conditions have not gone outside the limits I set a couple of months ago and no alarm has yet gone off in the app. It may work but I don't know.Remaining battery life is displayed in the 'Settings' page of the Smart Life App. Mine is showing 46% after 7 weeks use so it will probably last 13 weeks, i.e. 8xAAA batteries/year for each sensor. That only costs £4.08 for Amazon Basics batteries but it is inconvenient and you may miss an alarm especially as it is likely to be worse in cold weather. Deduct 1 star for poor battery life. AA batteries would last almost 3 times as long.

I was looking for some thermometers that I could use to log temperatures in various parts of my home. As with lots of things that are manufacturered (and sold) from abroad, its often difficult to work out whether a product does what it claims.Sadly, this item wasn't what I was looking for, although I suppose it does do the basics.There was the usual amount of difficulty in getting the thermometers to be picked up by the app in my phone, but having installed power strips, lights and other similar devices, I was expecting that. The logging of temperature seems only to happen on an hourly basis, rather than more frequently, and does not update as quickly as I would expect. Likewise, while there is connectivity with Alexa, this is limited to being able to display the temperatures in the Alexa app - there seems to no way to Ask her what the temperature is, and for her to give you the answer, let alone set up a routine that reacts to the temperature or humidity.
