check_vpd_drift
Compare current VPD to target range for a growth stage and detect drift with actionable alerts.
Instructions
Check if current VPD is within target range for a growth stage.
Args: device_id: The AC Infinity device code (from discover_devices) stage: Growth stage - one of: clones, seedling, veg, early_flower, mid_flower, late_flower
Returns: JSON example::
{
"device_id": "C58ZA",
"current_vpd": 1.58,
"target_range": [1.0, 1.5],
"stage": "veg",
"status": "HIGH",
"deviation": 0.08,
"alert": "VPD 1.58 exceeds target 1.00–1.50. Raise humidity or lower temperature."
}
``status`` is one of ``"OK"``, ``"LOW"``, or ``"HIGH"``.
``deviation`` is 0 when OK; positive when HIGH (kPa above upper bound);
negative when LOW (kPa below lower bound).
``alert`` is ``null`` when status is ``"OK"``.
On failure returns ``{"error": "...", "detail": "..."}``.Input Schema
