Everything meets in Home Assistant on your server: Davis feeds climate + soil, Protect feeds snapshots (an automation sends them to a vision model for scouting notes), and each valve is an HA switch — so watering automations can react to the same soil data you see here.

🛠️ Build plan

  1. 1
    🏠 Hub: your existing Home Assistant

    Nothing to buy — HA already runs on the Linux server. Install HACS for community integrations and the Mosquitto MQTT broker add-on (free, needed for the LinkTap valves in step 4).

    🛒 HACS install guide🛒 HA MQTT integration
    unlocks: the brain everything else plugs into
  2. 2
    🌦️ Weather: your existing Davis console

    Also nothing to buy — the Davis station keeps doing wind, rain, and outdoor temp. Add the WeatherLink integration in HA (local polling with a WeatherLink Live, cloud API otherwise). Skip Davis's soil add-ons; step 3 covers soil for a fifth of the price.

    🛒 WeatherLink HACS integration
    unlocks: rain, wind, and outdoor climate on the dashboard
  3. 3
    🌱 Soil: Ecowitt sensor kit (~$110)

    Three WH51 moisture sensors — tomato bed, lettuce bed, and one at root depth mid-corn — plus one WN34 soil temp probe in the greenhouse. They talk 433 MHz to one small WiFi gateway, which HA's native Ecowitt integration reads locally. AA batteries last about a season.

    🛒 WH51 moisture sensor ($18, ×3)🛒 WN34 soil temp probe (~$26)🛒 GW1200 WiFi gateway (~$30)🛒 HA Ecowitt integration
    unlocks: real bed + corn moisture, soil temp, VPD stays computed
  4. 4
    🚰 Valves: LinkTap D1 two-zone timer (~$180 with gateway)

    One D1 unit = both zones, with two built-in flow meters (real gpm on this dashboard) and fail-safe close. The gateway speaks MQTT to HA directly: local control, no cloud, no Zigbee dongle. ONE catch: both D1 outlets live at the same tap — so it fits if the greenhouse and corn drip runs both start from one water source (poly tubing carries water out to the corn). If the corn feeds from a separate far-away spigot instead, buy two single G2S timers on the same gateway. Bring it inside before first freeze.

    🛒 LinkTap D1 + gateway bundle🛒 LinkTap (official site)
    unlocks: the Irrigation card for real — watering automations driven by the soil sensors
  5. 5
    💧 Plumbing: drip kits (~$120)

    A drip irrigation kit for the four beds (emitters or soaker line off one manifold) and drip tape for the corn rows. Get a kit that includes a filter + pressure regulator — skipping those is the #1 way drip systems clog and blow fittings.

    🛒 Drip Depot irrigation kits
    unlocks: water actually reaching roots, evenly
  6. 6
    📷 Eyes: UniFi Protect camera (~$120–180 ea)

    1–2 UniFi cams covering the beds and field, RTSP enabled in Protect, HA's native integration. An HA automation forwards snapshots to a vision model for the scouting notes.

    🛒 UniFi cameras🛒 HA UniFi Protect integration
    unlocks: the Cameras card: motion, snapshots, AI ripeness/pest notes
  7. 7
    🔌 Wire this dashboard to HA (free)

    Long-lived token in HA, HA_TOKEN as a Wrangler secret, HA_URL in wrangler.jsonc (via a Cloudflare Tunnel since HA is on your LAN), fill the entity map in src/lib/ha.ts, redeploy.

    🛒 Cloudflare Tunnel docs
    unlocks: every number on this page becomes real — the mock switches off automatically

Notes: greenhouse 12×24 kit — only if not already standing — see Bootstrap Farmer link below · raised beds — or build from lumber · linktap d1 two-zone timer + gateway — both outlets at one tap; two G2S units instead if the corn feeds from a separate spigot · unifi protect camera — optional but fun.
