Creating one in the app
A guided, six-step popup — no field is required beyond a name.
- Open the Data sources page and click "+ New custom watcher".
- Pick "Simplified mode".
- Fill in the form: a name for the watcher, how often it should run, and an optional toggle to give it its own row on the Timeline.
- Choose how wide the module should be on your Home page — four sizes are offered, from a compact single column up to the full width.
- Choose how the data should be displayed — see Visualization templates for the full list, each shown with a small live preview so you can see roughly what it looks like before picking it.
- Click "Create module".
The moment you click Create, three things happen automatically: the watcher's folder and starter script are created on disk, the watcher starts running immediately (no restart needed), and a module showing its data — empty until the first data point arrives — appears on your Home page at the size and with the visualization you picked.
A confirmation screen shows you exactly where the folder was created and offers a button to open it directly in Explorer, so you can start editing the script right away — see Writing the watcher script for what to put in it.
