Price and buy
Smart temperature hygrometer can buy from Ebay or AliExpress, good price varies around about 18-20 usd shipping included.
there are similar versions on aliexpress, I have not tested them but I believe that the forms work.
Control accuracy is 0.1 °C it is a great advantage !
Small size only 56mmx17mm
Easy instrument control (explained later in post)
Owns all the main functions that need good datalager,notification alarm
Free app with simple instalation and operation
Here is cons
Although the replaceable battery is large and will provide a long run there would be a USB charge
Bluetooth is OK, but the thermometer is only suitable for direct connection to a mobile phone in range
My review of WS02:
My opinion on WS02 sensorblue is good working device all declared function working OK. APP Sensorblue work Ok , pairing with thermometer humiditymeter is simple all working for first time. App can add add multiple devices To add multiple devices, you can monitor multiple locations (rooms) through your smartphone.
The downsides are that the device could have a micro usb port for charging, it would be a level better. Maybe on aliexpress you will find a derived device with usb charging. If you are waiting for monitoring via wifi internet with different distances, it will be better if you are looking for wifi (not bluetooth) similar thermometer hygrometer from Sonoff or Tuya, for example.
