How-to guides
- Send numbers with multimeter:// links: Every multimeter://set parameter, a link builder, and copy-paste recipes for Terminal, shell scripts, git hooks, Shortcuts, Raycast, Python and Node.
- Script meters: Run a zsh command on a schedule and show the number it prints as a gauge, graph or text. PATH, the 10 second timeout, JSON output and 10 ready-made commands.
- Web address and JSON meters: Fetch a URL on a schedule and show a number from plain text or JSON. Key path syntax, the value/min/max format, refresh limits and API tokens.
- File meters: Point a meter at a text or JSON file and it updates the moment the file changes. The simplest way for any tool, cron job or app to feed the Mac menu bar.
- Switch from another menu bar monitor: What carries over from iStat Menus, Stats, MenuMeters and SwiftBar, what doesn’t, and how to set up the same meters in Multimeter in ten minutes.
