Irrigation bridge/irrigation.json
The policy that lets the helper fit a Rain Bird's program A, clock and rain delay to the weather. Without it, the helper never changes a schedule. Use "dry_run": true to see what it would do first.
Edit the JSON instead (for the settings the form doesn't show; it keeps them as they are).
Saving checks the file the way the helper will at its next start. A restart puts it to use.
