To control or receive statuses from a 3rd party device, you install a Link.
Note: You will need one link for each device.

2 x AAA batteries need to be replaced every two years.

No, you must install the link indoor.

You must install the Link near the device you wish to control.

1. You may need to replace the batteries. To check the batteries level, go to your app and check level.
2. The Device may not communicate properly with the HUB. Make sure that there is not a metal cabinet which interfere between the HUB and the device.
