## Questions & Answers

**Q: An I set this up so that Alexa makes an announcement when the door is opened?**
A: YES.  Not sure why it didn't work for a couple of people, but I set up all 4 of mine to announce on my Alexa devices, as well as give me a notification in the Alexa App.  For a couple, I also set them up to play an alarm noise and turn on lights.  Tested them and they all work.

**Q: Can you make it so sound comes out of the unit itself when the door is opened? And then shut it off remotely from your phone?**
A: The sound does come out of the unit. It beeps for about 4-5 times and then sbuts off by itself.

**Q: This pack comes with 4 detectors. If I purchase additional detectors, will I be able to connect them to the app, so they’re all on the same system?**
A: Yes it dose connect to the same system and you can change the name so you know what is what

**Q: Is this product compatible with the tuya? Is their a homebridge plugin that works for this item.**
A: It is compatible with Tuya and SmartLife according to the photos. If you install it in Tuya, you can now import it into Home Assistant which I believe has a homebridge link. Of course all of this takes a lot of technical effort and may not be for everyone.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to use and set up…
*by F***S on May 18, 2023*

I bought these sensors to monitor how often my pet sitter was actually taking out my dogs. I was able to set these upon the doors to each area, and set up alerts to tell me when to watch the doggie cam. You can set them up for inaudible alerts in just a few minutes. I’ve had these now for several months, and the battery life is long as well.

*by A***R on December 26, 2021*

These were fairly easy to set up and intall but they lose connection every couple of days and need to be reset/reconnected leaving us blind to our home if we are away at work or out of town. Definitely will be returning and looking for other options for door sensors
