Evening Settle20:51TRANSITIONacked-20:52Acknowledged: Evening settle check: current climate is cool/high-RH but within the intended sunset posture. Heat1 is active against temp_low 62.1F; VPD 0.32 kPa is just above vpd_low 0.30 with dew point margin 5.5F. Active plan iris-20260427-1952 already suppresses mist/fog, widens VPD hysteresis, and uses bias_cool +4 / bias_heat +1 for anti-oscillation. No tunable change needed. Resolved 20:52 MDT.
New forecast data22:51FORECASTacked-22:53Acknowledged: FORECAST update reviewed at 22:51 MDT. New 24h forecast matches active sunset plan assumptions: cold/high-RH overnight through morning, overcast/light solar until midday, brief mixed dry/solar window Tuesday afternoon. Active plan already suppresses overnight mist/fog, widens VPD hysteresis, uses bias_cool +4 overnight, and steps to moderately more permissive misting at 15:00... Resolved 22:53 MDT.

Validating previous cycle: iris-20260426-1951

Previous hypothesis: SUNSET overnight posture for 2026-04-26: tonight’s main challenge is cold, saturated outdoor air creating condensation/VPD-low risk while the greenhouse also needs steady heat through a 38-45°F low. I am keeping heating modest (bias_heat +2 to +2.5, not raising temp_low), holding bias_cool +4 overnight to prevent heater→vent oscillation, widening mist gaps, and making mist/fog conservative until Monday’s midday dry window. Expect gas to drive cost overnight; compliance should improve versus today’s 28.9% if VPD-low hours stay under ~2h and cold stress stays under ~1h. Lesson #2 validated: forecast <45°F, so use gas/slab retention rather than expensive temp_low escalation. Result: 2026-04-27 complete-day metrics: planner_score 35.9, compliance 29.1%, temp compliance 41.7%, VPD compliance 74.2%. Stress was almost entirely VPD-low: 14.77h VPD-low vs 1.53h VPD-high, with 0h heat/cold stress. Cost was USD 5.53, below the 7-day average USD 6.96; water 16 gal vs 217 gal 7-day avg; therms 3.585 vs 4.528 avg; kWh 22.26 vs 19.4 avg. Dew point safety succeeded: dp_margin_min 5.0F, dp_risk 0h. Hypothesis miss: suppressing mist/fog preserved safety and water but did not recover VPD-low; forecast also severely undercalled solar (694 predicted vs 1237 W/m2 actual). Score: 4/10

New finding: On cool/high-RH recovery days, mist/fog suppression alone preserves dew-point safety but can leave VPD below band most of the day. If dp margin is safe, the next strategy should add active dehumidification/ventilation stability and avoid treating all high-RH days as pure mist-suppression days. → Added to Lessons Learned

Hypothesis

Testing: Cool-high-RH recovery posture: suppress mist/fog on Monday and grade against VPD-low hours plus dew-point risk, then compare to Tuesday/Wednesday moderate dry-window posture. Expected outcome: Monday: VPD-low stress under 4h, dew-point risk under 1h, cost below USD 7.50, no setpoint_unconfirmed alerts from mister_all_kpa. Tuesday/Wednesday dry windows: VPD-high under 3h/day without repeating VPD-low >4h.

moderate dry-window posture: engage 1.4, all 2.0, gap 35, fog_escalation 0.45

Parameter rationale

mister_engage_kpa2.4 → 2.4; Mon outdoor VPD peaks only 0.94 kPa and RH remains high

prevent repeat of 11.3h VPD-low stress while keeping VPD-high under 2h

fog_escalation_kpa0.9 → 1.0; cool/high-RH day with prior dp_margin_min 3.1F

avoid fog-driven humidity overshoot and reduce dew-point risk hours below 1h

bias_heat2.5 → 0.0; gas cost was USD 5.04 yesterday; current temp/VPD are already in band

lower gas use toward 7d average while avoiding unnecessary heat cycling

mist_max_closed_vent_s180.0 → 120.0; VPD-low and condensation risk dominate today

limit sealed-humidity accumulation and hold dew point margin above 5F

Previous hypothesis: Cool, overcast, high-RH Monday should be managed as a VPD-low/condensation-risk day, not a dry-stress day. I am replacing the stale dry/mist-heavy posture with high mist/fog thresholds, short sealed windows, and modest heat bias only overnight; Tuesday/Wednesday dry windows get moderate mist readiness without repeating extreme-dry settings. Result: [backfill] compliance unavailable over plan window 2026-04-28 01:54 → 2026-04-28 13:35 Score: 4/10

Hypothesis

Testing: Cold/high-RH overnight anti-oscillation posture: bias_cool +4 and mist suppression should reduce vent/heater chatter and dew risk without forcing expensive continuous heat. Expected outcome: By Tuesday sunrise: dp_margin_min >=5F, dp_risk_hours=0, overnight vent transitions lower than today’s 129/24h pace, and therm usage below 7d average trajectory.
