Here is another budget priced Aliexpress item. Firstly, let me say that this device is widely available on Aliexpress from many sellers and at a range of prices. I paid £6.52, which is the lowest priced version I found and it took about two weeks to be delivered to me in the UK with free shipping from China as I bought three of them. Tuya make several other humidity sensors, some round and some square, some battery powered, some USB powered.

In the box, you receive the sensor/display itself, a USB power cable, and a well written and nicely printed user guide. Build quality is lightweight but seems of good quality with nothing looking likely to fail or fall off anytime soon.

This USB powered sensor displays the time, temperature and humidity on the slightly unstable kickstand supported desktop display. It also connects over WiFi to the Smart Life or Tuya apps to show this information on your phone with a graphical display of the data over a range of time periods. The Smart Life app, which is the one I mainly use, can be configured send alerts for low or high temperature and low or high humidity. The apps also connect with Google and Amazon Alexa. The app connected sensor can be integrated into timers and routines controlled through the apps. I have set up a routine to power on the dehumidifier when the humidity reaches a certain level and to power off when it returns to normal.

I found that it works well and I have had no issues with it so far.
But it's not all good. The display I think is a bit dim and also the lettering is quite hard to read as the LED matrix used is rather old fashioned and very basic. That is no big deal for me as I mainly use it with the app.

The main selling points are the remarkably low price and the integration with the Alexa and Smart Home ecosystems and so far I have found this to work perfectly on all three of the sensors I bought.
