The smoke detector can be connected and configured directly via the Tuya Smart or Smart Life smart app. No additional control panels or devices are required; it can operate independently. You can use the test button to check that the device is working properly every week. Mute function: if the alarm is false, you can temporarily mute it.  Very convenient and easy to use! Lightweight and small, with low energy consumption.
