C. About YoLink Control
4
YoLink Control is our unique device-to-device control technology. Using YoLink Control, YoLink
devices can be controlled without the Hub or an internet connecon. (Use of YoLink Control is
oponal; you can use the Automaon feature in the app OR use YoLink Control, but YoLink
Control offers the benefit of operaon without the Hub or internet connecon.)
One device controls another, directly. A device that sends out commands is called the controller. A
device that receives the commands is called the responder. Examples of a controller are a YoLink
Remote or Water Leak Sensor, while examples of a responder are a Siren or a YoLink Relay
The YoLink Remote can work as the controller of YoLink Control
C-1. Pairing
To configure your YoLink Remote as
a controller. Press and hold any of
the five ON buons (take the first
ON buon for example) for 5-10
