TendrilGrow

TendrilGrow

TendrilGrow is a Home Assistant custom integration for indoor cultivation. Install it from HACS, add one config entry per grow space, and map the sensors and cameras you already have. No hardcoded entity IDs.

Open your Home Assistant instance and open a repository inside the Home Assistant Community Store. Open your Home Assistant instance and start setting up a new integration.

Start here

  1. Install via HACS (restart Home Assistant after download).
  2. Walk through a complete 4×4 RDWC example.
  3. Fill Cultivation Plan (Growth Stage + Stage Started date).
  4. Optionally enable AI health checks with a camera.

What you get

  • Per-space device — helpers, chemistry, pumps, flush cadence, and AI on one Home Assistant device.
  • Cultivation clock — Stage Started is a date; Week In Stage is computed from it (feeds AI dosing and harvest projections).
  • Reservoir chemistry — prefer LocalTuya / Tuya Local on LAN; cloud Tuya OpenAPI is fallback-only.
  • Derived climate — VPD, dew point, estimated DLI from canopy air + PPFD.
  • Pumps — RDWC / chiller / air switches, power, estimated daily cost.
  • Flush tracking — Flush Now, interval, days-until, overdue reminder.
  • AI advisor — quality-first score, issues, mix-order feeding markdown, live vs sterile reservoir rules.
  • Timeline and tasks — calendar events and a to-do list for flush / stage / critical health.

Control is manual and opt-in. TendrilGrow does not turn pumps or lights by itself.

Decision support, not a safety system

TendrilGrow assists monitoring and agronomy advice. It does not replace safe electrical, environmental, or horticultural practice. Validate automations and control actions before you rely on them.
