Possible Cause
Action
524 remote operation
with Nexia is intermittent.
1) Bridge and 524 have marginal Z-wave
communications.
1) In Nexia: Go to Edit Home, Advanced
2) Find the 524 and click on “Test Connection” button.
3) If test results are less than 80%, enroll a Z-wave repeater
(plug-in dimmer or appliance module) into the bridge, and plug
repeater into outlet midway between bridge and 524.
4) Repeat steps 1-2 and verify communications is greater than
80%.
524 remove operation
with Nexia previously
worked, but now does
not.
1) Bridge and 524 have lost the ability to
communicate via Z-wave
1) Verify Nexia bridge has not been moved. If yes, then
move bridge back to original location and then re-test remote
features.
2) Verify bridge is connected to AC power and to an active
Ethernet (internet) connection.
3) Verify a Z-wave repeater has not been unplugged or
removed. If yes, then restore the repeater to its original
location.
4) Verify that new wireless equipment has not been added to
the home. If yes, temporarily unpower the new equipment and
then re-test 524.
