TomatoFarm Live

tomatofarm.live

This started as a small hobby idea and then, as hobby projects tend to, got completely out of hand. TomatoFarm is a real indoor farm with sensors, cameras, pumps, mostly 3D-printed parts, a .NET backend, TimescaleDB, a Blazor frontend and six real plants. The part worth talking about: every farm decision runs through a council of four LLMs (Claude, ChatGPT, Gemini and Mistral). They read the same farm state, reason about what to do next, and effectively vote. I call it MoEoT - Mixture of Experts of Tomatoes. :) It's not a startup, not a product, not an ad. Just one guy building something because it sounded fun, slightly unreasonable, and technically interesting. The interesting part isn't "AI grows plants." It's everything built around the AI, to keep it safe to leave running unattended. A huge chunk of the code exists purely for that. A few things I learned the hard way: The AI can never touch hardware directly - it can only suggest. Every hardware action the council proposes, has to pass through multiple safety layers it cannot bypass: hard limits, cooldowns, tank-level checks, all fail-closed. A council decision literally can't force its way past a safety rule. That one bound...
