* Please note: if your YoLink devices are online (in wireless range of a YoLink hub with an internet connection) any settings you may have made previously in the app may conflict with your desired standalone/offline operation as configured by your SirenFob device pairings and arm/disarm status. For example, if you are using YoLink security products in a vehicle or RV, intended for applications without internet access, your devices will operate as expected while they have no internet connection, but when your car or RV is parked at home (in range of your YoLink hub), if you have settings in the app that control your siren or that determine when your alarm devices are armed or disarmed, unexpected behaviors can occur. Consider your settings in the app, to avoid conflicts with your SirenFob settings, paired devices, or arm/disarm status.
** If using a mobile security application, while your YoLink alarm devices are out of range of a YoLink hub, please note, alarm activation (e.g. a break-in) will not be displayed on the app, and you will not receive SMS, email, or other notifications. Your siren once activated, if not silenced, may drain the batteries down.
