The new mechanism

Every other “smart” controller is guessing. Yours measures.

Weather-based controllers water your landscape off a zip-code forecast — a guess. SoilDrops reads the real moisture in your soil and waters only when your plants actually need it.

The old way

Weather-guessing controllers

Rachio, Orbit, Rain Bird & co. pull a forecast for your zip code and guess what your landscape needs.

  • Overwaters on a cool, dry day
  • Skips watering on a hot, humid one
  • Never sees what's happening underground
The SoilDrops way

SoilDrops measures real soil

A wireless sensor in the ground reports live moisture, so the AI waters on ground truth — not a guess.

  • Waters only when the soil is actually dry
  • Skips the cycle when it's still moist
  • Per-zone intelligence, 24/7
You can see it. A physical sensor in your soil — visible, undeniable proof.
You can prove it. "Skipped today — soil still moist" right in the app.
You can bank it. Homeowners can cut water bills up to 30%, guaranteed.

The sensor that ends the guessing

Wireless Soil Moisture Sensor

Reads real moisture, not a forecast

The sensor measures the actual water content in your soil and feeds it to the AI — so every zone waters on ground truth, not a zip-code weather guess.

Real-time data, at root depth

Probes read moisture 6 inches down and transmit live readings, so the system knows the moment a zone goes dry — or skips it while it's still wet.

Long Life Span

Sensors have a battery life of ~2 years and replaceable batteries, so you won’t have to worry about replacing the sensor itself.

Mower Friendly

Sensors extend just 1.5 inches above the soil, allowing you to mow over them without any damage.

Here’s the deal

Most “smart” controllers still guess off the weather. SoilDrops pairs an 8-zone Wi-Fi controller with wireless sensors in your soil — so the AI waters on what your landscape is actually doing, then catches leaks and adapts to the weather on top.

  • Sensor-driven precision watering
  • Installs in under 30 min — works with your system

Frequently Asked Questions

What's included in the Starter Kit?

The SoilDrops Starter Kit includes the 8-zone Controller plus wireless Soil Moisture Sensors. You get real soil readings from day one, so SoilDrops can water from measured root-zone moisture instead of a forecast guess.

How is this different from a Rachio, Orbit, or Rain Bird controller?

Those are weather-based controllers: they pull a forecast for your zip code and estimate what your yard needs. SoilDrops adds a wireless sensor in your actual soil, so the AI waters on real, measured moisture instead of a regional guess — then layers weather and plant data on top. It's the difference between checking the forecast and checking the ground.

Why does the Starter Kit cost more than basic controllers?

A $35 timer just switches valves on and off on a clock — it has no idea whether your soil is wet or dry. Even most $150–$250 “smart” controllers only guess from the weather. The Kit includes the sensors that measure real soil moisture, which is what actually cuts your water bill up to 30% and keeps your landscape healthy. Most homeowners earn the difference back in water savings.

Is Soildrops compatible with my current irrigation system?

Yes, for the vast majority of installed systems. If your existing controller uses standard 24V AC solenoid valves (which most residential systems do), Soildrops works as a direct replacement.

How much water can I save?

Most households save up to 30% compared to a traditional timer. With sensor-driven scheduling from the Starter Kit, you get the most accurate watering and the biggest savings.

How does AI scheduling work in the Starter Kit?

The free core scheduling tools use zones, schedules, weather, plant profiles, and paired soil sensors. Optional hands-off Autopilot can take over watering decisions if you enable it.

How many sensors do I need?

Most landscapes start with 4 sensors — about one per irrigation zone. Add sensors for zones with different plant types, sun exposure, or soil conditions, and you can add more from soildrops.com any time.

Where should I place the sensors?

In the center of each zone, at root depth (about 3–4 inches for turf, deeper for shrubs and trees). Avoid zone edges, soggy spots, concrete or rocks, and sloped low points where water pools.

What are the Wi-Fi requirements?

The controller needs a standard 2.4 GHz Wi-Fi network (not 5 GHz). Bandwidth requirements are very low — any stable signal works. Sensors talk wirelessly to the controller and don't connect to Wi-Fi themselves.

How long does installation take?

About 10–15 minutes for the controller, plus ~3 minutes per sensor. The full setup is walked through step-by-step in the Soildrops app.

How long do the sensor batteries last?

1–2 years on a single CR2032 coin cell. The app sends a low-battery notification well in advance.

Does the controller require a subscription?

No — manual control, zone schedules, live soil-moisture readings, basic AI scheduling, and CultivAI plant care are free for life. Premium hands-off automation features are optional add-ons managed in the App Store or Google Play.
