LOCAL CONTROL. NO SUBSCRIPTION.

Truly own
your Gardyn.

A Gardyn is a good piece of hardware with a Raspberry Pi inside and a cloud account in front of it. seedypod replaces the cloud with software that runs on that Pi: lights, watering, sensors, cameras and grow reminders, all on your own network.

A ONE-MINUTE TOUR.

Meet your tower.

Turn the tower in 3D, see Gardyn's light zones, scrub a plant from seedling to harvest, and check the whole system at a glance, all in the real web UI.

Truly own your Gardyn. — A silent tour of seedypod core against the simulated tower. Nothing has run on a real Gardyn yet.

IN YOUR BROWSER. ON YOUR NETWORK.

Your whole tower, in view.

Dim the grow light on a curve, run a bounded watering cycle, track all 30 pods through a grow cycle, and scrub through camera timelapses. No account required.

01 / LOCAL

No account. No telemetry.

02 / SAFE

Every pump run is bounded.

03 / OPEN

REST, MCP and MQTT.

TWO TIERS, ONE CONTRACT

A daemon for the hardware. A core for everything else.

Both run on the Pi already inside your Gardyn, or core can live on any LAN box. Use them from a browser, Home Assistant or the iPhone app.

01 — THE HARDWARE

hald

A small Rust daemon that owns the pins and buses. Every pump command passes a safety guard: bounded runs, dry-run interlock, over-temperature cutoff, latched faults.

Read the HAL reference02 — THE BRAINS

seedypod core

Hono, tRPC and SQLite. Schedules, grow cycles, alerts, camera captures, and the React web UI, with an OpenAPI REST facade and an MCP endpoint.

Open the user guide03 — YOUR HOME

Home Assistant

hald publishes MQTT discovery, so Home Assistant sees the light, pump and sensors with nothing else installed. Core adds grow reminders and a water-now button.

Connect Home Assistant04 — YOUR POCKET

iPhone app

Your tower in 3D on your phone. Tap a pod to harvest or plant it, set the light, run a bounded watering, and clear alerts. Finds your unit with Bonjour; no account.

BUILD ON IT

Your agent, your dashboard, your script.

Every capability is a tRPC procedure first, then generated as REST and exposed as MCP tools with declared limits. The safety guard applies no matter which door you come in through.
