Questions people ask us most
Will it work with my sprinkler system?
Yes, if your current timer plugs into a wall outlet and each zone has its own wire plus a shared common wire. That's a standard 24 VAC system, which is what nearly every in-ground system in the US uses. SoilDrops runs up to 8 zones, plus a master valve or a pump-start relay. It isn't for battery-powered (DC) valves, two-wire decoder systems or hose-faucet timers. Not sure? Text a photo of your timer to 626-657-3580.
Do I need an electrician?
No. The valves run on low-voltage 24 V. Take a photo of the old wiring, move each zone wire to the same number on SoilDrops (the common wire, usually white, goes to C) and plug it into the outlet. The one exception: if your old timer is wired straight into household power with no plug, have an electrician swap it.
What Wi-Fi does it need?
Your home Wi-Fi, 2.4 or 5 GHz, with no router changes. Setup runs over Bluetooth: open the app, it finds the controller, pick your network and enter the password. Before you mount it, check that your phone shows Wi-Fi at that spot.
What happens if my Wi-Fi goes down?
It keeps watering. The plan is stored on the controller, so every zone still runs on time, and the app catches up when the connection is back.
When does my pre-order ship, and when am I charged?
Pre-orders ship after Christmas, in the order they were placed. You're not charged until your order ships, and we email you the day it goes out. Need one sooner? The original SoilDrops Controller is in stock and ships in 1–2 days.
How many sensors, and where do they go?
One for each zone you want on Autopilot. Push it in near the middle of the zone, away from concrete, downspouts and the wettest or driest corner. It takes about five minutes each. Zones without a sensor keep running on free weather-smart schedules, and you can add sensors any time.
How far can a sensor be, and what powers it?
Each sensor talks straight to the controller: up to about 100 ft in the open, less through walls or metal. It runs on one coin battery (CR2477) that lasts about 1–2 years, and the app tells you when it's getting low.
I already have SoilDrops sensors. Do they work with Gen 2?
Yes. It's the same Soil Sensor. Pair them to the new controller in the app.
Can a zone water more than once a day?
On its plan, each zone waters at most once a day, because longer and less often is better for roots. For new seed or a hot afternoon, start an extra run any time with Quick Run in the app.
I have more than 8 zones.
Use two controllers, one for each group of zones. Today each controller has its own app login.
Is there a subscription?
Only for Autopilot, which plans your watering and watches for leaks: 30 days free, then $60 a year (about $5 a month) for every zone on the controller. It's billed through the App Store or Google Play, so you cancel there any time. Everything else is free: app control, schedules, weather skips, heat-wave adjustment, valve monitoring, wiring and battery alerts, and live soil readings.
How does the free video setup call work?
Scan the card in the box, pick a time, and a SoilDrops person joins you on video while you wire it up. Most people don't need it; it's there so you're never stuck. Rather talk? Call 888-427-6838 or text 626-657-3580, 8am–8pm PT.
Does it work with Alexa, Google Home or HomeKit?
Not yet. There's no Alexa, Google Home, HomeKit or Home Assistant support. Everything runs from the SoilDrops app, and with Autopilot on there's rarely anything to ask for.
What if it's not for me?
Tell us within 30 days of delivery and we'll email you a prepaid label. You get a full refund, even if you've already installed it. After that, the 1-year warranty covers defects.
