For the sake of it, I tried selecting it, restarting the Add on, then restarting Core. No change. So I went back and changed back to the original device and restarted again.
The last update must have over written the /boot/config.txt file. It deleted a line that had been added to enable the HAT. This rendered the HAT inoperable.
I had the same issue - I was able to fix it by choosing the device from the drop-down in the Z-Wave JS Add-on configuration. It was unset for me after the update (I did not check if if was set before the update). My update path was 0.1.50 → 0.1.51.
had the same problem started with a aeotec sensor 6 falling off ,
in the end had to reinstall zwave js and zwave 2 mqtt , 8 hrs later still waiting to get my locks and remotec back but the sensor6 is back …
I just started to see this error message (Failed to connect: Cannot connect to host core-zwave-js:3000 ssl:default [Connect call failed (‘172.30.33.0’, 3000)]) when I upgraded HA from 2022.5.5 to 2022.6 so all my Zwave devices are unavailable. My Zwave-JS is at 0.1.60 which seems to be the latest. The device selected in the Zwave configuration is /dev/serial/by-id/usb-Silicon_Labs_Husbz_Smart_Home_Controller_41500EAD-if00-port0. There is a port1 device in the list also but I think that is the Zigbee; I tried changing it to port1 but it wouldn’t stay selected after restarting. I am running in a VM environment; my ZWave/HA had been working fine for well over a year. I have rebooted the host PC with no improvement. Any suggestions?
Did you find a solution to the problem? For me it started approx 24 hours after I upgraded to 2022.6.6. Updated zwave_is to 0.1.61, but that didn’t fix it.
