Z-Wave JS and SkyConnect integrations both stopped working

Configuration
1

Both Z-Wave JS and SkyConnect v1.0 have started failing to setup.

I think this must have occurred after an update. But I wasn’t paying close attention and I’m not certain.

I haven’t had time to troubleshoot so I have applied a couple of updates since this problem started. Neither update seemed to help.

I’m using a SkyConnect stick and the Aeotech zwave USB stick.

Z-Wave JS error:

Retrying setup: Failed to connect: Cannot connect to host a0d7b954-zwavejs2mqtt:3000 ssl:default [Connect call failed ('172.30.33.0', 3000)]

Is it possible the USB controller on my Raspberry Pi has died? Like I don’t understand what could cause both to stop working simultaneously.

5

Are you sure the device paths of the two sticks didn’t swap? Using the raw device paths like this is highly discouraged. You should be using /dev/serial/by-id paths so they cannot change.

6

Aha!

Ok I switched the USB path over to the id for the zwave controller and rebooted and that fixed both zwave and skyconnect.

It’s not clear to me if zwave pointing at the wrong usb device was somehow messing up skyconnect, or if doing a full machine reboot is what fixed skyconnect.

Thank you very much!
