It gives you temperature and humidity. With Tuya Smart you can program routines. For example, I have the home alarm connected to the smoke detector.

I bought a total of three units. Very easy to connect. Initially, I noticed multiple false alarms, so I contacted the seller and the manufacturer. A firmware update was provided very quickly (after about 2 days), and the detectors are now working very well. I recommend the manufacturer and the product.

This is a replacement for one that had network connection issues. For now, it works. The app also shows temperature and humidity.

14 days to Dnieper. There are no complaints about the quality of manufacturing and materials. There were no problems connecting to TuYa, all functions are working. Temperature and humidity readings are kept consistent with neighboring sensors. The sensor works even from NiCd batteries with a voltage of 1.2V. If there are any issues during use, I will update the review later.
