Try these troubleshooting steps if your ZEN71 is unavailable, shows as offline, or is unresponsive to commands!
As a 700 series Z-Wave device, the ZEN71 Switch has a range of up to 500 feet (line of sight). Even so, interferences like large furniture, thick walls, and metal elements can shorten range. Ultimately range is determined by the specific structure of your home and the strength of your mesh network. If you're seeing connectivity issues, we first recommend healing your Home Assistant network. This function refresh the connections between your hub and devices so that the hub can find the most efficient route to each device.
-
Click on the Z-Wave Control Panel in Home Assistant
-
Under Z-Wave Network Management, click Heal Network
If healing the network didn't help get your switch get back online, here are some other things that may help:
-
Try excluding and re-pairing the switch directly from its target location. It could be that the hub hasn't found the most efficient communication route to the switch and excluding it will help the hub find the switch better.
-
Add a Z-Wave signal repeater in a location between the switch and hub. This can be any Z-Wave device that doesn't rely on battery power. If the issue is caused by interference or range, a signal repeater can help strengthen and stabilize connectivity. After adding the repeater, it's a good idea to heal your network once more.
-
Bring the Z-Wave hub closer to the switch, removing and re-adding the switch with the hub in the new spot. If the switch includes successfully, stays connected, and is responsive to remote commands, it's possible the previous location was out of the hub's range or there are too many interferences in that particular area.
-
Check if your switch box is made out of metal or plastic. Metal is really effective at disrupting Z-Wave signals and can prevent signals from being sent or received. If possible, try moving the hub closer or adding a Z-Wave signal repeater between the switch and the hub.
