Frodig is a little open device that reads the soil and waters each plant exactly when it’s thirsty. Add your green friends, glance in now and then, and rest easy.
Pop the little hub by your plants and connect it to Wi-Fi. It pairs with a 6-character code — no app store hoops.
One soil, light and temperature sensor per pot — up to four plants per hub. Calibrate once and you’re set.
Frodig sips water to each plant exactly when the soil runs dry. You just glance in now and then.
Three sensors per plant and one careful pump. That’s all it takes to keep things green.
A soil-moisture sensor in every pot — Frodig waters only when the soil actually needs it, never on a dumb timer.
Light and temperature sensors flag a plant that’s baking on the sill or sitting in a cold draft.
One small tank and four gentle pumps. Group them by room and see the whole windowsill at a glance.
Vacation mode eases off while you’re away, and the water-level sensor tells you before the tank runs dry.
We started Frodig as a weekend project because we kept letting our plants dry out. There’s no pricing page, no upsell — just a friendly tool we’re happy to share. Use our hosted version for free, or run your own.
Every line of the app and firmware is open. Read it, fork it, send a pull request.
Schematics and a parts list are published. Solder your own, or order a kit from a fellow grower.
Run the whole thing on a Raspberry Pi at home. No cloud account required, no data leaves your house.
A handful of plant-killers who got tired of dead ferns. Everything is decided in the open.
