If any device is not functioning consistently, the network may have trouble communicating with the device, either because it is too far from the nearest node or because there is an obstruction blocking the Z-Wave signal. If this happens, Alarm.com recommends the following troubleshooting steps.

Verify the device is powered on

Make sure the device is powered and functions properly on its own (outside of the Z-Wave network).

Verify the device is properly enrolled

Check that the device has been added into the Z-Wave network by looking at the Z-Wave devices list. For more information about updating the Z-Wave equipment list, see Request an update on the Z-Wave equipment list.

Verify range

Make sure that each Z-Wave device is within 25 feet of the nearest AC-powered Z-Wave device in the same network. Placing devices at a greater distance can cause significant reduction in communication ability. Note that devices running on battery power do not repeat Z-Wave signals—they only receive them.

Verify Z-Wave functionality by bringing the device closer to the module and then testing the Z-Wave communication while it is in close proximity. 

If communication is successful when the Z-Wave device is close to the panel or module, either:

• Move the Z-Wave device to a different permanent location that may have more consistent communication.
• If moving the Z-Wave device is not an option, install one or more Z-Wave plug-in modules to act as Z-Wave range extenders. Place the Z-Wave plug-in extenders midway between the failing node and the nearest non-battery powered node that has not failed the rediscovery.

Delete and re-enroll the Z-Wave device

If the node is not communicating properly when it is in close proximity to the panel or module, delete the Z-Wave device from the network, re-add it, and run the Network Rediscovery.

After completing one or all of the above troubleshooting steps, run a Network Rediscovery a second time to verify that the network has been repaired. If, after completing the preceding steps and running a Network Rediscovery, the Z-Wave device is still having trouble communicating, contact Alarm.com CORE Technical Support.
