The "Can't Detect Device" error can point to an issue with connectivity, range, or configuration. Here's where to start:

If the dimmer is wired up and working well manually, start with Update Neighbor Nodes. This is a useful feature in your Vera interface that will refresh the network and help Vera find the most efficient route to your dimmer. Give this a try if you're experiencing connectivity issues and see the "Can't Detect Device" error: 

1. Use a computer to log into GetVera.com and select your hub.
2. From the Dashboard, select Settings
3. Select Z-Wave Settings
4. Click on the Advanced tab
5. At the bottom of the advanced tab, you'll see a GO button to run the “Update Neighbor Nodes”. The process can take several minutes or over an hour depending on the size of your Z-Wave network.

Another thing to try is to exclude and re-include the switch from the installation location. Just like Update Neighbor Nodes, it's possible that Vera hasn't found the best route to communicate with the switch. Exclusion acts like a reset and may improve connectivity. 

Finally, if your switch is installed in a metal switch box, this can shorten the device's range. Metal is a effective at blocking radio signals, and it will affect your mesh network's strength and communication between device and hub. If possible, try installing a Z-Wave plug / range extender between the dimmer and the hub or moving your Vera closer to the switch temporarily to see if the metal box was the issue. Any non-battery powered Z-Wave device will repeat signals, like in-wall switches, relays, smart plugs, or dedicated range extenders.

If you're still experiencing issues after trying all the above, please let us know. We'll be happy to work with you until we find a solution.
