Soil-Moisture-Driven Irrigation with VegeHub & B-Hyve

This page documents the irrigation upgrade for the vegetable garden beds using real soil moisture data to trigger watering through the existing B-Hyve irrigation controller.

The goal: water only when the soil actually needs it, not on a timer.

🥕 Project Overview

The system uses:

VegeHub WiFi Control Hub (Vegetronix)
- Handles wired soil moisture sensors (1–4 per hub)
- Sends readings to Home Assistant (local API)
- Has an onboard relay (optional to use)

VH400 Soil Moisture Sensors (Vegetronix)
- Extremely accurate, long-term stable, outdoor-rated
- Low power consumption
- Ideal for vegetable beds

B-Hyve Irrigation System
- Already installed and working
- Exposed to Home Assistant as zone switches
- Automations will trigger B-Hyve based on moisture thresholds

Your initial project plan:

Phase 1: 1 VegeHub + 4 sensors → one sensor per bed
Phase 2: Add second VegeHub + 4 sensors (8 total)
Goal: Each irrigation zone waters *only* when its beds are dry

Home Assistant logic:
  - Compute per-bed moisture (avg or median)
  - Compute zone moisture = min(bed A, bed B)
  - Trigger watering only when moisture < threshold
