ZWave not loading after update...again

Here we go again!

I updated the core to 4.11 and ZWave no longer works. Here’s the log but it’s the same issue when we moved from 3.13 to 4.8.

I am running a razberry 2 on a pi 3b+. Any help is greatly appreciated.

Verify path to zwave stick.

That was one of the first things I tried. I even deleted the zwave integration and added it back and same result.

This doesn’t look correct, it’s usually /dev/tty/ACM0, but best to use the /dev/serial/by-id/....

That’s the value I’ve always used and that is listed in Supervisor -> Hardware.

Actually that might be the case. I wonder if the hardware info is wrong. There might be a missing / in there but strange it would all of a sudden stop working. Is there anywhere I can edit that path if it’s setup under integrations?

You can manually edit it in .storage/core.config_entries

Since you have a razberry, ttyAMA0 sounds correct. ttyACM0 is for the USB sticks.

Is it possible the OS update replaced the config.txt? Bluetooth needs to be disabled.

That I have not checked! Is there a way to do that using samba or terminal? I’d rather not have to unhook everything to plug it into my computer.

You should be able to issue the command cat /boot/config.txt from terminal/SSH

I think the OS manages the config.txt to enable the serial port, so might not be that problem. But… there have been issues recently, most recent one was closed as fixed for 4.10.

That was it! I guess the update reset my config.txt file. Had a backup, restored it and all is back to working. Thank you all!
