How it works

The authority split, the ladder, photoperiod, sensor trust, plants and stages, journals, learning, and the grow tools.

• 01Who decides what — hub vs brain
  The authority split: hub-owned safety and demand, brain-owned targets, tasks, rules and the Sonoff driver; why demand proposals are shadow mode; what happens when the brain or hub goes away.
• 02The climate ladder, failsafe and reality gates
  How the hub turns targets into appliance demand: the rung order, min-off, hysteresis, ladder waits, reality gates (ineffective, relay mismatch), the failsafe, priority tent and the shared exhaust.
• 03Photoperiod, holds and catch-up
  The hub's lights clock, auto photoperiod, sunrise/sunset ramps, the dark-period guard, manual light hold, catch-up and its surprises, the 4×8 open loop and lamp plugs, and how schedule shifts are confirmed.
• 04Sensor trust — offsets, clamps, held and stale
  The pipeline a reading goes through before it is shown or acted on, and the horizons that turn a value into HELD, stale or rejected.
• 05Plants, stages, harvest window and DLI
  How a strain profile becomes Want bands, how expected stage and the harvest window are computed, what the DLI estimate is made of, and the plant · probe · assignment model.
• 06Zigbee and Tuya — roles, tasks and placement
  How a paired device becomes entities: capability class, role, zone and placement, tasks and policy state, climate deltas, and the additive rule for plugs.
• 07Journals, reminders and the grow record
  The four journal layers, frozen snapshots, typed actions and custom actions, photos on disk, reminders anchored to entries, retention, export and the archive written on retire.
• 08Energy, learning and calibration curves
  Nameplate vs learned airflow, the anemometer method, CFM ownership, Phase A/B climate learning, the space energy model and tariff cost, and what soft cal does and does not do.
• 09Runoff trend and grow alert sensitivity
  How runoff minus input is charted per plant, when it raises an alert, and the one setting that sets the grow tools' alert thresholds together.
• 10The run report and its grade
  What the brain freezes when you log a harvest, how yield is normalised, and what the execution grade does and does not judge.
• 11Drying and curing zones
  What flipping a zone to Dry or Cure starts, the dry strategies, mould risk, jar pucks in a cure fridge, and what the brain never controls.
• 12Procedures — SOP checklists
  Short standard procedures that open when something happens, tick themselves from the journal or the sensors, and write their close to the journal.
• 13The reservoir Mix panel
  Checking a nutrient mix against the plants it feeds and your own earlier mixes — verification, not prediction.
