Bottom line: The ZWave integration will NOT install on a fresh HA system on a barebones Pi4.
(This is related to this topic but with more information and looking at it with a different point of view.)
Do I have to have a ZWave dongle on my system for the integration to install? I can’t get the integration to install at all on a new Pi4 system with no extra hardware.
More details:
I have a Pi4 that worked okay with ZWaveJS2MSQTT with an Aeotec ZStick 7. I changed that system to Home Assistant and added the ZWave integration with no problem. But, for various reasons, I wanted a fresh install of HA on that system. I write out a new HA image to an SD card, turned off the Pi4, then put in the new HA image and started it up. Whenever I added the ZWave integration, I’d get vague and useless errors. I’ve had problems, in the past, with the device nodes being unreadable in some programs, and it meant I had to write a udev rule to make sure the ZWave node in /dev was accessible to the program. (I think that happened to me a good while back in HA, when I first started it, but I’m not sure. I know it did happen to me last week with openHAB.)
That made me wonder if the dev node file could be an issue, so I pulled the USB ZStick and wrote a new HA image to a new SD card and put that in.
So this is a Pi4 with no extra hardware. It’s a brand new install of HA, updated, and it won’t install the ZWave integration. Note, also, that previously, I could install ZWave with no problem. So something must have happened to this Pi4 hardware that makes it suddenly unable to install this.
Here’s screenshots. I go to Settings->Integrations->Add Integration:
I pick the ZWave integration, the one that’s selected, the 2nd one in the list and, on a fresh system, I get this:
I continue with the box checked (which is what worked in the past and works on my other HA system). Then I get this:
I wait and watch. Then I get a flicker as a dialog box comes up, but disappears in an instant. It’s larger than the status box saying installation of the add-on has started, but I can’t see anything on it because it’s almost instantly replaced by this:
So I go back to the start and try installing again. I get the dialog asking if I’m using the ZWaveJS add-on again. I proceed as before and now, since the ZWaveJS add-on is installed, I get this:
So if I install fresh, I get “Error.” If I install with the ZWaveJS add-on already on my system, I get “Unknown Error Occurred.”
I have tried this with the USB Z-Stick on the system. No difference.
This appears to be the error message (I have log levels set to debug in configuration.yaml) and stack trace:
