Frequently-Asked Questions

I installed the Smoke alarm and set it up as instructed, but the app displays an "abnormal" installation status. What should I do?

Firstly, have you pushed the activate button to activate the detector? If so, try re-connecting the detector and the base, making sure that the metal circle and three probes are properly connected. Then, long-press the test button to perform a self-test. If the detector makes a sound and the notification is sent from the app, it means that the devices are working normally.

However, if the issue still persists, it is possible that the metal circle or the probes may be damaged or malfunctioning. In this case, please contact YoLink Customer Support with your purchase invoice (showing that it was sold by YoSmart) and shipping address to arrange for a replacement unit.

I would like to receive alerts on my phone from my existing smoke alarm system, but there is no trigger or device to do so without replacing the entire system with a smart one. What can I do?

While it is true that there is no direct trigger or device to make your existing smoke alarm system smart, some customers have used YoLink products to achieve this. One option to consider is the YS7707-UC contact sensor, which can be connected to your smoke detector. Please refer to the manual's "Contact Closure Device/Equipment Installation" section for instructions on how to install the contact sensor. This may allow you to receive alerts on your phone when the smoke alarm is triggered, without having to replace the entire system.
