Solar peak planning checkpoint12:55SOLAR_MAXackedAcknowledged: SOLAR_MAX no-op: live solar 238 W/m² is below the day's forecast peak (~723 W/m²) and only modestly above the immediate 152 W/m² hour; indoor VPD is 1.26 kPa with a healthy 11.6°F dew margin, history is stable near 1.14–1.28 kPa rather than climbing rapidly, and controller/equipment are appropriately idle. Existing afternoon plan covers the forecast ramp; no tunable nudge is justified. Resolved 12:56 MDT.

The scheduled waypoint already widens mist gap and raises engagement/fog thresholds for the overnight humidity rebound; no immediate write is justified. Resolved 18:04 MDT.

Hypothesis

Testing: Test live-VPD gating: delay aggressive wet assist through the cold dawn, then open it at the confirmed dry ramp. Expected outcome: Keep overnight dew-risk and VPD-low stress at 0 h; keep late-morning controller-attributable VPD-high stress under 1 h without excess water.

Hypothesis

Testing: Test live-VPD gating across a short dry-ramp/cold-recovery day: open wet assist after observed VPD clears high edge, then taper at cloud transition. Expected outcome: Keep dawn wet recovery within 3h, controller-attributable VPD-high stress under 1h, no VPD-low stress after 15:00, dew-risk 0h, and mister water within 220 gal.

Conditions

RH minimum

32.0%

Solar peak

723.0 W/m²

Cloud average

21.0%

Cool wet dawn; brief dry solar/VPD ramp near 13:00; abrupt cloud, rain risk, and humid cold recovery after 14:00. Apply forecast corrections.

Expected stress windows

vpd_highhigh · 2026-09-19T10:00:00-06:00 to 2026-09-19T14:00:00-06:00

Live-VPD-gated wet assist; engage excess 0.05, all-zone 0.25, fog excess 0.20.

vpd_lowhigh · 2026-09-19T15:00:00-06:00 to 2026-09-20T06:00:00-06:00

Taper wet duty after cloud transition; preserve 8F dew margin and avoid overnight wet assist.

Parameter rationale

mister_engage_kpa1.6 → 1.24; Corrected VPD peaks near 1.9kPa at 12:00-13:00 after wet dawn.

Start assist near the active high edge without extending the dawn-too-wet condition.

mister_all_kpa1.9 → 1.44; Dry ramp and east-zone VPD 0.74 require bounded zone support before peak.

Serve the dry outlier during the ramp while limiting whole-house water use.

fog_escalation_kpa0.4 → 0.2; Raw VPD peaks 2.36 at 13:00, then cloud collapse at 14:00.

Make heavy assist available during the short peak, then taper before cold humid recovery.
