Weather-aware smart irrigation

Your garden hired a tiny, obsessive watering gang.

Your plants never go thirsty — and you never think about it. Absurdly simple on top, uncompromising underneath: it reads the weather and waters each patch to the exact millilitre.

And I'll skip tonight's run — there's 14 mm of rain due tomorrow. No sense watering a puddle.

The brain

It watches the sky so you don't have to.

Most timers run on a schedule and call it a day — even in a downpour. That's dumb. Wet My Plants reads the forecast down to your coordinates and gives every patch exactly what it's short. Nothing wasted.

rainy Rain incoming? It holds fire.Reads the forecast, subtracts the rainfall, skips the run. We don't water mud.
air Föhn on the way? It steps in.That warm, dry alpine wind empties the soil fast. The engine sees it coming and tops up the thirsty patches — before anything wilts.

We do the maths

Not a timer. A climate model for your garden.

Most watering systems are dumb — they spray in the rain and sulk through a heatwave. The Wet My Plants watering engine is the opposite: uncompromising Swiss precision that knows the exact thirst of every patch and tops up only what nature didn't. No wasted water. No bloated utility bills. No dead grass.

MSc Built by an atmospheric & climate scientist. Our founder holds an MSc in Atmospheric & Climate Sciences. At the core is a data-driven climate model — the professional-grade kind agriculture relies on to water at scale, now tuned for your garden. Not marketing. Actual science.
Step 01 radar

Read the sky

Pulls an hourly, hyperlocal rain forecast for your exact coordinates — not a city-wide guess.

Step 02 function

Run the model

A professional-grade climate model works out how much water the sun, heat, wind and humidity pulled from each patch today.

Step 03 water_drop

Balance the books

Subtracts the forecast rain, adds each plant's thirst, and lands on the exact dose — down to the millilitre.

Step 04

Send in the gang

The engine opens each valve for precisely that volume — automatically, on your own hardware, offline.

No wasted water. No bloated utility bills. No dead grass. The gang does the digging — the science does the thinking — and you take the credit.

Meet Master Pebble

Stone-cold accuracy. Unshakable calm.

Master Pebble is the little hub on your countertop — the coolest head in the garden. He runs the whole climate model right on the device with stone-cold precision, works out who waters and exactly how much, and keeps the valve gang in check. No cloud. No drama. No dead plants.

  • target Stone-cold accurate. Runs a professional-grade climate model to the millilitre — mental clarity, scientific rigour, not a drop of guesswork.
  • diversity_1 Keeps the gang in check. Every valve answers to Master Pebble. He decides who opens and for how long — and shuts the master valve the instant a hose misbehaves.
  • self_improvement Unshakably calm. Reads the sky, runs the numbers, dispatches the gang — all day, every day, without breaking a sweat.
  • cloud_off Works off-grid. Wi-Fi drops or the internet goes down? Master Pebble keeps watering. The brains live on the device, not on some faraway server.
The valve gang

Nobody remembers "Valve #3."

So we stopped shipping serial numbers. The moment a valve joins your garden, it gets a name, a face, and a patch to look after. You always know exactly who watered the roses.

Sir Sprinkles
Flowers

Knighted himself. Waters the front border like it's a coronation.

Dr. Drizzle
Front lawn

Prescribes exactly nine litres, twice weekly. No refills necessary.

Madame Bloom
Roses

Only the roses. She has been very clear about this.

Captain Puddle
Greenhouse

Runs a tight ship in the greenhouse. Not a drop out of place.

Breezy Reed
Back lawn

Furthest from the hub and completely unbothered about it.

Duchess Dew
Berries

Treats every berry like the crown jewels. They rather enjoy it.

Mr. Squirts
Vegetables

Enthusiastic. The vegetables have learned to brace themselves.

Old Sage
Herbs

Been doing this a long time. Waters slow, waters right, says little.

Don't like a name? Rename any of them, any time. The cheek stays in the name — the status always tells you the plain truth.

Setup

Five minutes. Then forget it exists.

Plug it in. Connect the app. Let us do the dirty work. If you need a manual longer than this, you're overthinking it.

Plug in Master Pebble

The little garden hub. Give it power and Wi-Fi once — it quietly runs the whole show from your countertop.

Meet the hub

Twist a valve on the tap

It finds itself, names itself, and joins the gang in seconds. Add one per patch — beds, pots, the greenhouse, the lot.

"Found it — say hi to Dr. Drizzle"

Draw your garden. Walk away.

Sketch your patches in the app, tell it what's growing, and the engine takes it from there — rain, shine or heatwave.

Then go to the Badi
The serious bit

Cheeky name. Deadly serious about your water.

The jokes live in the names. When it comes to real water on real plants, the system is built to fail safe — every single time.

gpp_good Can't flood, even if it crashesEvery valve opens with a hardware shut-off timer. If the software dies mid-run, the water still stops.
water_damage Stuck valve? Master off.Unexpected flow gets caught and the master valve closes — no water quietly running across the patio for hours.
battery_alert Low battery won't half-openA valve too weak to close again is never asked to open. Better a skipped run than a stuck one.
wifi_off Works with the Wi-Fi downWatering lives on the hub in your garden, not in the cloud. Internet's just for checking in from the Badi.
