Just a tip; there's [a set of very handy system nodes](https://flows.nodered.org/node/node-red-contrib-os), which includes a disk-space node, as well as CPU usage, free RAM, and system uptime. They use the [Node.js OS library](https://nodejs.org/api/os.html) and are compatible with both Linux and Windows. I've been using these on a Pi for the last couple of years with zero issues.
