Concept

Vision

Section titled “Vision”

GrowRig is an open-source, local-first platform for monitoring and automating grow boxes, tents, rooms, and small controlled-environment installations. It should offer the usability of an integrated commercial ecosystem without requiring proprietary device buses, mandatory cloud accounts, closed mobile apps, manufacturer-specific equipment, or undocumented automation behavior.

A user should be able to:

  1. buy a preconfigured system;
  2. assemble a recommended system from verified hardware; or
  3. build and modify everything using open software and reference hardware.

The problem

Section titled “The problem”

Proprietary grow ecosystems often deliver good onboarding and tightly integrated devices, but create lock-in around controllers, connectors, mobile apps, cloud services, equipment catalogs, and firmware updates.

DIY Home Assistant systems are flexible but expose low-level concepts — entity IDs, MQTT topics, GPIO numbers, helpers, Modbus registers, ESPHome configuration. GrowRig hides these behind a grow-specific domain model while keeping them accessible to advanced users.

Product thesis

Section titled “Product thesis”
Integrated product experience
        + Home Assistant compatibility
        + Open controller hardware
        + Local autonomous operation
        + Replaceable equipment

Hardware strategy

Section titled “Hardware strategy”

The project supports three hardware paths:

  • Existing hardware — anything exposed through Home Assistant: ESPHome, Zigbee, MQTT, Modbus, Matter, Shelly, Bluetooth, local cameras.
  • GrowRig reference hardware — documented, reproducible designs using accessible components such as XIAO modules, Grove sensors, standard PWM fans, and RS-485 adapters.
  • Official hardware — later, proven prototypes can become supported products.

User experience

Section titled “User experience”

Normal users should move through a guided flow and never need to hand-write Home Assistant automations:

Create grow environment → Discover devices → Assign roles → Test equipment →
Configure safe fallback → Choose targets or recipe → Start automation

Long-term differentiation

Section titled “Long-term differentiation”

The strongest differentiator is not an “AI grow mode.” It is a system in which every decision can be executed locally, simulated, tested, observed, explained, reproduced, and overridden safely.
