If you've added your dimmer and see the Offline error in your Wink app, here's what to try:

Give Network Discovery a go. This is a feature in Wink's app that allows you to refresh the network, and may help Wink find the most efficient route to your switch. 

1. Open your Wink app and tap the Menu button in the top-left corner of the screen
2. Tap on Hubs
3. Tap on the gear icon in the top-right corner
4. Select your hub
5. Scroll down and tap on Z-Wave
6. Tap on Z-Wave Network Discovery

Wait for the Success alert before exiting out of your app. As soon as you see the alert, check your switch again to see if it's still showing Offline. If you'd like to learn more about Network Discovery and Wink Z-Wave controls, here's the official resource.

If that doesn't help, try excluding and re-including the dimmer directly from the installation location. Similar to Network Discovery, it's possible that Wink hasn't found the best communication route between it and the device. Exclusion is like reset, and it may help the hub establish solid connections with the dimmer.

Another thing to check for is the material of your switch box. Plastic boxes are ideal. Metal boxes interfere with the Z-Wave radio signal and shorten overall range. To see if the metal box is causing the dimmer to drop offline, we would recommend installing a Z-Wave signal repeater (any non-battery powered Z-Wave device like smart plugs, relays, or dedicated range extenders) between the dimmer and Wink to see if connectivity improves. Z-Wave Plus devices have longer range than regular Z-Wave devices, so if possible go with a Z-Wave Plus range extender!
