So your ZEN75 is included to Home Assistant but is showing offline or is unresponsive to Z-Wave commands? We can help!
Blockages like large furniture, thick walls, and metal elements can shorten Z-Wave range. Ultimately, the range of any given device is determined by the specific structure of your home and the strength of your mesh network, unless connecting via Z-Wave Long Range.
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
Here are some other troubleshooting steps to try if the above doesn't help:
-
Remove and re-add the switch in case the hub hasn't found the best communication route to it.
-
Add a Z-Wave signal repeater between the switch and hub if you are connecting via the mesh. It can be any Z-Wave device that doesn't rely on battery power. An extra repeater can help strengthen and stabilize connectivity. We recommend healing your network once more after adding the repeater.
-
If you can, bring the Z-Wave hub closer to switch and try excluding and re-including it again. If you're able to exclude and include without issue and the switch stays connected, then the switch may be out of the mesh range or surrounded by a lot of interferences.
-
Make sure your switch box is not made of metal. Metal is really effective at disrupting Z-Wave signals and it 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.
-
Try adding the switch as a Z-Wave Long Range device. You will need to have a 700 or 800 series Z-Wave stick and be running the Z-Wave JS UI integration for Home Assistant.
