Since I also plan to use access VoltCloud from within a (Node.js-based) server, I’m currently developing an NPM package with a VoltCloud client for Node.js.
The source is available on GitHub, the package itself may be installed using
npm install voltcloud-for-servers
The “good cases” have already been implemented, a “smoke test” (also included in the source) illustrates how to use the package.
Hopefully, I may be able to implement error handling and write automated tests by end of this week.
