Your ZEN55 Smoke & CO Detector Bridge is successfully included, but it's showing as “offline" in Hubitat? This is suggestive of a potential range or configuration issue. The easiest place to start is with a Z-Wave Network Repair.

You always want to start by ensuring that your Hubitat hub is up to date on its platform version. Next, simply follow the easy steps below to run the Z-Wave Repair to refresh your Z-Wave mesh network connections:

1. Open Hubitat in your Internet browser

2. Go to Settings

3. Click on Z-Wave Details

4. Click on Repair Z-Wave

Once the repair is successful, you will see a "Z-Wave Network Repair finished" confirmation.  

If the repair does not resolve the issue, please give the troubleshooting steps below a try:

• Try excluding the device and re-including it. This ensures the hub is able to devise the best route to the ZEN55, and acts as a soft Z-Wave reset for your device.
• Try adding a non-battery powered Z-Wave device, or a Z-Wave signal repeater, between the hub and relay, if you have one available. This will help improve communication between the two devices. You will need to run another Z-Wave Repair for the additional device to be recognized and used in the communication path with the ZEN55.  

Please don't hesitate to contact us if you have any questions!
