New forecast data07:02FORECASTackedAcknowledged: Forecast update matches the active plan: cool/cloudy humid morning, modest dry window 16:00-19:00 with outdoor VPD ~1.6 kPa, then cool/humid overnight. Existing 09:30 and 15:00 waypoints already suppress mist/fog during the humid morning and shift to moderate dry-window mist readiness in the afternoon. No temperature, cloud, wind, or humidity shift large enough to justify replacing the plan. Resolved 07:03 MDT.

Existing 12:30/15:30/19:30 waypoints already suppress mist/fog while damp, enable dwell gate, then lower mist/fog thresholds for the dry window; no tunable change needed. Resolved 08:44 MDT.

No tunable or plan change needed. Resolved 09:45 MDT.
New forecast data10:44FORECASTackedAcknowledged: Forecast update matches current split-pattern plan closely: peak temp 63F vs planned 62F, RH minimum 14% vs planned 13%, and the late-afternoon dry window remains 16:00-19:00. Solar is somewhat spikier around 13:00-14:00 but still covered by the existing 12:30/15:30 waypoints and dry-window mist/fog posture. No tunable changes needed. Resolved 10:44 MDT.
New forecast data11:44FORECASTackedAcknowledged: Forecast update matches the active split-pattern plan: peak outdoor temp ~63F vs planned 62F, late-afternoon dry window remains RH 14-18% with moderate solar, and current greenhouse conditions are stable with safe dew-point margin. No tunable changes needed. Resolved 11:44 MDT.
New forecast data12:44FORECASTackedAcknowledged: Forecast update matches the active split-pattern plan: cool/cloudy early afternoon followed by the expected 16:00-19:00 dry window (RH ~14-18%, outdoor VPD ~1.55-1.61). Current greenhouse VPD is in band with safe dew-point margin, and the 15:30 waypoint already lowers mist/fog thresholds for the dry slot. No tunable change needed. Resolved 12:45 MDT.
New forecast data13:43FORECASTackedAcknowledged: Forecast update matches the active split-pattern plan: short 16:00-19:00 dry window is already covered by the 15:30 dry-window waypoint, and overnight high-RH/cool conditions are covered by the evening/morning recovery waypoints. No significant >5F temperature, cloud-regime, wind, or humidity shift requiring setpoint changes. Resolved 13:44 MDT.
New forecast data14:43FORECASTackedAcknowledged: Forecast update checked against active plan iris-20260428-0735 and current setpoints. Near-term temperature remains within the planned cool/dry split pattern (peak ~61F vs 62F planned), humidity dry window is milder than planned rather than worse (RH ~19% vs 13-16% expected), and solar is moderate this afternoon. Existing 15:30 dry-window waypoint and tomorrow midday posture remain appropriate; no tunable change needed. Resolved 14:44 MDT.
Peak Stress14:58TRANSITIONackedAcknowledged: Peak-stress transition checked: greenhouse is stable and in/near band (76.9F, VPD 0.92 kPa, RH 71%, dew point margin 10.2F), ESP32 is IDLE with all cooling/fog/misters off, and the 14:47 deviation plan already replaced the aggressive dry-window posture with moderate cloudy-dry settings. Forecast remains cool with only moderate late-afternoon dry risk, so no additional tunable change is warranted. Resolved 14:59 MDT.

Tonight turns cold/cloudy/humid after a dry sunset; tomorrow is mostly cool/overcast with only a brief midday dry/solar window, already covered by the current moderate/suppressed mist thresholds and conservative fog posture. Current greenhouse is stable in IDLE at ~69F, VPD 0.70 kPa, dp margin ~10F. No tunable changes needed. Resolved 18:36 MDT.

Active plan already shifts to evening posture at 19:30 with higher mist/fog thresholds and mild heat bias, so no tunable change is needed. Resolved 18:54 MDT.

Existing plan already uses conservative evening/overnight posture and moderate Wednesday daytime mist/fog thresholds; no >5F or cloud-regime shift requiring a tunable change. Resolved 19:35 MDT.

Evening Settle20:53TRANSITIONackedAcknowledged: Evening settle check: current conditions are stable near band (63.3F, VPD 0.44 kPa, dew-point margin 6.9F). Heat1 is already maintaining the cool evening band, vent/fog/misters are off, and the active sunset plan has upcoming frost-adjacent overnight waypoints with bias_heat/bias_cool posture for anti-oscillation.

New forecast data22:35FORECASTackedAcknowledged: Forecast update matches the active sunset plan: frost-adjacent low near 35F, high cloud cover/low solar overnight into morning, and only a modest midday dry window. Current plan already keeps mist/fog suppressed overnight, carries warmer pre-dawn bias, delays cooling to reduce heater/vent oscillation, and relaxes to a moderate midday posture.

Previous hypothesis: SUNSET overnight plan: tonight’s main challenge is not dry-air stress; it is a cold, saturated outside air mass (41-46°F, 79-93% RH) plus crop-profile scoring pressure. I expect the greenhouse slab to hold the room near 61-64°F while heaters handle brief dips. The plan suppresses mist/fog overnight, widens humidity hysteresis, keeps sealed-mist windows short, and uses bias_cool +4 with bias_heat +1 to +1.5 to prevent heater→vent oscillation while protecting dew point margin. Tomorrow afternoon has a modest dry window, so the plan becomes moderately more permissive on misting after 15:00 without using the hot-dry aggressive posture. Expected outcome: overnight dp_margin stays >=5°F with 0 dp-risk hours, VPD-low stress improves vs today’s 2.2h, and gas cost stays below the 7-day average therm burn while avoiding unnecessary continuous heating. Result: [backfill] avg compliance 52.4% (stress 14.8 h) over plan window 2026-04-28 13:35 → 2026-04-29 01:54 Score: 3/10

Hypothesis

Testing: Enable Phase-2 dwell gate for the first split high-RH/dry-window day and test balanced dehumidification + short dry-window mist readiness against VPD-low and transition churn. Expected outcome: For Apr 28: VPD-low <8h, VPD-high <2.5h, dp_risk_hours 0, cost <USD 7.50, and heat/vent transition counts lower than Apr 27’s ~100+ churn.

Parameter rationale

sw_dwell_gate_enabled0.0 → 1.0; Yesterday had 100+ heat/vent transitions and today begins with heaters on under high RH

reduce relay/mode churn while preserving THERMAL_RELIEF and safety preemption

mister_engage_kpa2.5 → 1.3; Tue 16:00-19:00 outdoor RH 13-16%, VPD 1.46-1.64 kPa

hold VPD-high stress under 2.5h during the short dry window

fog_escalation_kpa0.9 → 0.35; PR-A allows vent+fog at vpd_high_eff + fog_escalation; late afternoon dry slot needs fast correction

use short fog assist only if misters lag, without morning fog overshoot

vpd_hysteresis0.5 → 0.35; Yesterday VPD stayed below band 14.77h; current dp margin is safe at ~8F

improve VPD responsiveness and reduce VPD-low hours below 8h while keeping dp_risk_hours at 0

Previous hypothesis: Today is a split-pattern day: cold/high-RH morning with VPD-low risk, then a short late-afternoon dry window (outdoor RH 13-16%, VPD ~1.6 kPa) under moderate solar. Yesterday proved mist suppression alone is too blunt, so today’s posture keeps mist/fog suppressed while damp, turns on the dwell gate to reduce vent/heat whipsaw, then lowers mist/fog thresholds only for the 15:30-19:30 dry window. Expect VPD-low to improve materially without recreating condensation risk. Result: Yesterday finished at planner_score 54.6 with 52.9% both-axis compliance. Temp compliance was the lower individual axis (64.4% vs VPD 75.6%), but measured stress was dominated by VPD-low overshoot: 4.63h VPD-low, 0.03h VPD-high, 0h heat/cold stress. Cost was USD 5.76, below the 7-day avg USD 6.65; water was 85 gal vs 216 gal 7-day avg, therms 3.01 vs 4.12 avg, kWh 25.72 vs 19.6 avg. The late-day cloudy-dry deviation avoided severe high-VPD/heat stress, but the posture remained too humid for too long and did not solve both-axis compliance. Score: 6/10

New finding: On cool/cloudy spring days, the main humidity risk can flip from VPD-high to VPD-low. When forecast solar is mixed and outdoor temps stay near 60F, avoid aggressive fog/mist posture after the dry window; keep fog_escalation_kpa wide and mister gaps longer unless observed VPD is actually rising above band. → Added to Lessons Learned

Hypothesis

Testing: Deviation response: replace aggressive dry-window waypoint with moderate cloudy-dry posture after solar forecast bust. Expected outcome: Avoid new VPD-low/dew-point risk this afternoon while keeping VPD-high stress under 1h through sunset.

Hypothesis

Testing: Overnight anti-oscillation posture: bias_cool +4 with modest bias_heat +2 at pre-dawn to reduce cold stress without provoking vent dumps. Expected outcome: By Wednesday morning: cold stress <3h, heat stress <1h overnight, dp_risk_hours 0, cost_total tracking below USD 6.50, and no sustained VPD-high episode before noon.
