Each preset has a default threshold designed for most use cases, but you should adjust it to your reality. For example: how much notice you want about lightning depends on your crop and your terrain.
Where do I change it?
Go to Advanced → My Vigía Alerts, tap the preset you want to adjust. In the detail screen, each target has a "pill" showing the current threshold (e.g. 10.0 km for Lightning nearby, 25.0 km for Severe thunderstorm).
Tap the pill and an inline editor opens with two controls: a direct numeric field (where you can type) and − / + buttons to adjust step by step. Change the value and it saves automatically when you lose focus or press Enter.
Defaults adapt to crop type
If the target is a Field with a defined crop type, the default threshold may differ from the city's. For example:
- Lightning nearby in city: 10 km — In vineyard: 15 km (you want more advance notice) — In cereal: 8 km
- Frost in most crops: class 2 — In cereal: class 3 (cereal tolerates more cold)
These defaults are applied when you activate the preset. You can change them any time afterward.
Validation
Thresholds must be numbers within the allowed range. If you try to save an out-of-range value, the change is not applied.
Bulk changes
For now, editing is one target at a time. If you want to set the lightning radius to 15 km across 5 targets, you need to tap 5 pills. We're evaluating "Apply to all targets" if it's requested often — reach out at support if that would help you.
