Why 5 and not more?
The current limit is 5 Fields per user. It's a conservative number chosen for two reasons:
- Performance: each Field triggers advanced data workers (ET0, frost, AQI). More Fields = more load on the background batch processes. 5 is a good balance between coverage and cost
- Product: most growers we tested had 2–4 active farms. 5 covers that with room to spare. If you're hitting the limit, reach out and we'll look at a higher-capacity tier
What happens if I try to create a 6th?
The form shows the error "You've reached the 5-field limit". The "+ Add field" button in the selector is also disabled when you're at 5.
How do I delete a Field?
Two places:
- From Settings → My Fields, tap the Field → "Delete"
- From the Field's detail screen, scroll to the bottom and tap the red "Delete" button
It asks for confirmation because the operation is destructive: it deletes the Field plus all associated Vigía alerts (records with target = Field#X).
What happens to each thing after deletion
Vigía alerts on that Field
They're deleted. If you had "Frost" active on 4 fields and the city, after deleting field #3 you're left with 4 active targets (3 fields + city). Presets on the deleted Field disappear; presets on other targets remain intact.
Devices that had that Field selected as "active"
If one or more devices were viewing the dashboard with that Field selected, the system automatically resets them to "main city". So when you open the app, the dashboard starts on your city again (it doesn't get stuck in a broken state).
If it was your "primary" Field
The "primary" flag is released. No other Field is automatically promoted — if you want another primary, set it manually from Settings → My Fields.
Advanced data already computed
Historical ET0/frost/AQI data for the Field isn't deleted from the backend (kept for auditing) but is no longer shown anywhere. If you recreate a Field at the same coordinates, it reuses the same anchor city and recovers that city's historical data.
Can I "move" a Field to different coordinates?
Yes — edit the Field from Settings → My Fields → tap the Field → Edit. Change lat/lng (or pick another point on the map) and save. The system automatically re-links to the nearest anchor city. Associated alerts keep pointing to the same Field (target_id doesn't change), but advanced data recalculates over the new coordinates.
Can I share a Field with another user?
Not yet. Each Field is tied to a single user. If two people operate the same farm, each needs to create it in their own account. We're evaluating "shared fields" for teams in a future release.
