In the ZWaveJS config, what do you have set for the Serial Port? Does this match what is in the hardware view of HA?
I had a lot of issues on reboots until I changed VirtualBox to pass the serial port and used that instead of USB.
Those were ack errors vs unavailable though so may not be helpful at all…
No, there is a config menu in ZWaveJS with a dropdown where you select your Serial Port.
Then you can check your Hardware to see it HA is recognizing anything on that port.
Might help to add some details of your setup. How are you running HA, Zwave device, etc.
Running HA on a Rpi 3B, with a Nortek controller Zwave / Zigbee
The configuration matches the hardware address…like I said sometimes it all works, other times I get the error, its like something is coming up before zwave.js is ready
Possible, but I don’t know what that would be. All I have is zwave.js in the devices menu and on the left hand side menu as mqtt, so not sure whats causing the issue…
