[kellermix]

Hi.I can't get the leviton dimmer to pair with HS.
Manual says hold the dimmer pedal for 7 sec and tap again.LED on dimmer blinks green.
Start HS add node.

Add Node started...
Activate the 'Add to Network' function on the device...
Activate the 'Add to Network' function on the device...
Activate the 'Add to Network' function on the device...
A new node is being added...
Error - Add Node Failed reported by controller - you may try again. A "Restart" has been done on your controller.

I also factory reset the dimmer but still no luck.
any thoughts?

Figured it out.the switch needs to be super close to the z-awve interface to link

After linking, were you able to communicate over a longer range (move the interface away from the switch), or do these leviton z-wave switches just always need to be close?
