I recently updated my UZB from 5.4 to 5.7 using Z-Way Expert UI, now all my nodes in Home Assistant Z-Wave JS UI are showing as dead and cannot be pinged. Any idea why?

I recently updated my UZB from 5.4 to 5.7 using Z-Way Expert UI, now all my nodes in Home Assistant Z-Wave JS UI are showing as dead and cannot be pinged. Any idea why?

So it looks like I had to set the frequency back to US after the firmware update as it defaulted to EU. Once that was done, all nodes were back.
