Today we received a new smart device from Kerui. It can work with Kerui alarm system but also with Sonoff RF Bridge.
In my case, I am using Sonoff RF Bridge connected to Node-Red and I will post a tutorial on how you can make your own smart doorbell.
This device can be used as a doorbell but it can also be used as an emergency/panic button.
From the package:
- Waterproof (I don’t know what grade but it’s well build )
- 433 MHz
- Transmission distance is up to 100m in open area
- 12V battery – included
- Comes with some two-sided tape for easy installation
