Equipment Inventory

About 172 ESPHome entities across relay-backed equipment, sensor streams, 49 grow light fixtures, and 70 active mister nozzles.

This is a public equipment map, not a wiring guide. It intentionally describes models, control boundaries, and relay names without publishing instructions detailed enough to replicate mains wiring. Raw reference notes remain in the private/local wiki; public readers should use this page as the canonical sanitized version.

North wall service core with Lennox heater, motorized intake vent, copper irrigation manifold, stainless sink, Rinnai water heater, and utility pump
North wall service core: heat, intake air, irrigation manifold, water, utility sink, and house-side access all meet here.
Kincony KC868-E16P relay board with 16-channel relays, DIN-rail breaker, transformer, and color-coded wiring
Relay and low-voltage control hardware. The public docs describe the boundary; they are not wiring instructions.

Clean and fertilized wetting paths are separate relay outputs where installed. South and west have clean and fert mister paths. Center has a clean mister path plus clean and fert center drip/wetting paths. Firmware applies the same direct-wet gate to misters, drip lines, fert paths, and flush paths before any automated plant wetting is allowed.

Important Control Boundary

Some catalog entries are compatibility names or physical paths with greenhouse-specific plumbing semantics. The relay map below preserves those names because telemetry and firmware refer to them. The source-of-truth control boundary is: ESP32 firmware owns relay state, the dispatcher owns validated setpoint delivery, and direct wetting is blocked outside the global activity/per-zone wet windows unless the direct-wet gate is explicitly disabled.
