Snapshot file (index.json) location

[pnpebeling]

I have configured the ZWaveOptions storage.cacheDir, and it appears to be used. However, the driver still complains about a missing folder "C:\snapshot\build\node_modules@zwave-js\config\config\devices". If I create this folder, a "index.json" file is created containing what appears to be mfg database entries. Is there a configuration setting to affect the target location for this file?

Hi @pnpebeling

The Cache DIR is used for Network cache (Node Values - to ensure values are restored at start up) - not device config files.

The Driver builds an index where the device configs are stored, but as this is a Read Only FS (the PSI) - it will fail.
It causes no issue - just a verbose message.

C:\snapshot - is specific to the PSI build process, during the stage that it creates the R/O FS - to be honest... I wont try and create it, but if it causes no issue, then go head 😄.

The internal FS - should not be concerned with, I'm not sure what effect it may have.

HOWEVER,
The driver has the ability to "move" the embedded device config folder, so I will try and add that in, which I believe will address the message you see, it will result in the device config files being written to this alternate location (outside the PSI)

The option is deviceConfigExternalDir - so I will test, and if all good, will add that option.

cacheDir - Network Cache
deviceConfigExternalDir - Directory of config files (I will add)
deviceConfigPriorityDir - Custom config files

See : https://zwave-js.github.io/node-zwave-js/#/api/driver?id=zwaveoptions

@AlCalzone
Would like to know if that will work?

Setting deviceConfigExternalDir to silence the index not being created due to the R/O FS?

As the config files are embedded, will using this option silence the index warning?

[AlCalzone]

deviceConfigExternalDir supersedes the embedded configuration dir, so it should silence the warning (assuming that directory is writable).

@pnpebeling

I'll add deviceConfigExternalDir a bit later today.
I think the initial run with it set, will cause an initial dump of the configs files to this directory that you set.

[marcus-j-davies]

The option deviceConfigExternalDir has now been added (untested)
it will need to be an absolute path, else it will try and resolve it from within the PSI I think

ZWaveOptions.storage.deviceConfigExternalDir

Just tried it ... seems to work. Warning message is gone and designated folder is populated. thankx -p

Thanks for reporting the success @pnpebeling
