Open-source Raspberry Pi controller

Run your grow chamber
without paying SaaS rent.

Frutero is a local-first controller for monotub fruiting chambers. Schedule lights, mist by humidity, stream your camera, and get AI contamination warnings — all on your Pi, no account required. Built for indie growers who want real automation for a chamber sitting on their kitchen counter.

Free Hobby tier — 1 chamber, always free. No credit card.

AI Advisor

Temperature spiked 4°F since yesterday. Check ventilation. No contamination risk detected in latest image.

Temperature trend — last 24h

Built for growers, not for VCs.

Every feature exists because a grower needed it. Not because it looks good in a pitch deck.

AI Advisor

Claude or Ollama reads your sensor trends and camera images. Flags contamination risk, pinning issues, and temperature drift before they kill a batch.

Live Camera & Timelapse

Stream your chamber over LAN. Snapshots from the dashboard. Auto-generated timelapse when you archive a batch.

Smart Mist Control

Mist triggers below your humidity threshold. Safety clamps prevent dry-fires — max-on, min-off, and daily cap enforced at the GPIO layer.

Photoperiod Scheduling

12/12 light cycles (or any cron). Boot-time state restore brings actuators back to the right state after a Pi reboot.

Batch Tracking

Track every grow from inoculation to harvest. Phase transitions, yield per batch, AI retrospective when you archive.

Smart Alerts

Telegram, email, webhook, or browser push. Notified when sensors go silent, temperature drifts, or AI spots contamination.

One chamber is free. Scale when you need to.

1

Install on your Pi

One command: ./install.sh. Node.js, SQLite, systemd service, TLS cert — all handled. Idempotent, so re-run anytime.

2

Connect hardware

2-channel relay, DHT22 sensor, USB camera, ultrasonic mister. Standard GPIO pinout — no soldering skills required.

3

Grow locally forever

Fully functional without ever signing up. Your data stays on your Pi.

4

Upgrade to Fleet (optional)

Connect additional chambers to the cloud dashboard. One view, cross-chamber comparisons, fleet-wide AI insights.

Simple pricing. No surprises.

Questions

Is my data going to the cloud?

No. The Pi controller stores everything locally in SQLite. You can run it forever without ever connecting to the internet. The cloud Fleet is opt-in, and even then the Pi only makes outbound connections.

What hardware do I need?

A Raspberry Pi 4B, a 2-channel relay module, a DHT22 temperature/humidity sensor, and optionally a USB camera and ultrasonic mister. Full pinout in the repo docs.

Can I run this on Ubuntu or macOS?

Yes. The controller works on any Debian-based Linux or macOS for development. GPIO obviously needs a Pi for real hardware control, but the dev mode with stubbed sensors runs anywhere.

Do you sell hardware kits?

Not yet. We publish the exact BOM so you can source parts yourself from Amazon, Adafruit, or AliExpress.
