I found this product as an alternative to Zigbee connected sensors. I have no Zigbee-router between the Zigbee Bluetooth-protocol and the usual Wifi-protocol, and didn´t like the idea of having to invest 50€ in one at the moment.
People have told me that Wifi-sensors EAT battery and that the Zigbee Bluetooth was much less battery hungry. That might be true, but I have had this sensor now, since almost a year and never hade to change the three AA-cells even once.
The sensor was easy to set up by inserting the batteries, starting the Tuya-app, clicking on the “+” for adding a device, choosing “sensors” and then “Temperature and humidity sensor – Wifi”. Filling in the name of my WiFi network (You need to actually be connceted with Your mobile to the network You want to install the sensor on AND have the “mobile data” turned OFF, so that ONLY ONE IP-network – the Wifi-network – is active, the sensor can´t bind its IP to the mobile network as it has no 3G/4G/5G capability). Mind You that these products can ONLY be connected to 2.4GHz Wifi, so DON´T select a 5GHz Wifi, even if You have one available. Fill in the password of this Wifi and press “Next”. If You keep both the mobile and the sensor reasonable close to the Wifi-router, it should install in a snap. If it doesn´t, the usual suspects are: sensor and mobile not on the same Wifi-network OR wrong password OR to far away from the router for installation. Once installed the sensor can function at greater disance, so You can move it to the desired position.
Click on the now installed sensor in the app and You should have a similar screen as below. You can switch between temp/humidty at will and see the graph of readings below.
The reason that this WiFi-sensor preserves batteries quite well, seems to be that its NOT sending its readings as a push message all the time, but rather only as a pull message when You ask it of its readings through the app. That is if You dont ask it to set an alarm, like: “IF temp falls below 10 C THEN push alarm message to the Tuya-app in the mobile”. Then of course its SHOULD push a message, IF this happens often it might drain Your batteries.
Also I have found these push mesages, that seems to go through Tuyas servers before reaching Your mobile, to be a bit unreliable, sometimes they do and sometimes the do not act as instructed. So don´t use these push alarms if You really need to know.
As You can see it has both the Smart Life and Tuya Smart app logos. They work fine with both AND with Nedis Smart Life app too. As well as with Siri, Alexa and Google Home however this I have not tested.
I will rate this product 85/100 for pricing, ease of installation, ease of use and battery life, only minus is unreliablity of alarm messages.
