Does Rachio keep watering if the internet goes down?

Yes. Home Assistant controls Rachio over the local network, and the controller runs its own schedules on-device. An internet outage takes out remote access and forecast lookups, not the watering itself.

Do I need a subscription to use Rachio with Home Assistant?

No. The integration path Selora deploys is local and subscription-free. Watering history and controls stay on your own hardware instead of a manufacturer cloud.

Can Home Assistant skip watering when it rains?

Yes. Automations can set a rain delay or skip a program based on forecast data, an on-site rain sensor, or soil moisture readings, usually more flexibly than the manufacturer's own app allows.

Rachio & Home Assistant

Irrigation

Rachio integrates with Home Assistant to bring sprinkler zones and watering schedules into the same system that runs the rest of the home. Start, stop, and time zones from the dashboard, and build automations that skip watering when it rained overnight or when a soil moisture sensor says the ground is already wet.

Because Home Assistant talks to Rachio locally, schedules keep running when the internet is down and there is no subscription attached to any of it. Watering history, zone runtimes, and rain-delay state all live on your own hardware.

How Rachio Works with Home Assistant

Getting Rachio connected to Home Assistant and running reliably.

1

Local connection

Home Assistant connects to Rachio over the local network. Zones, programs, and sensors appear as entities you can control and automate.

2

Zones & schedules

Run any zone for a set number of minutes, trigger full programs, or set a rain delay, from the dashboard, voice, or an automation.

3

Weather-aware watering

Combine Rachio with forecast data, a rain gauge, or soil moisture sensors so watering skips automatically when it is not needed.

Common Rachio Issues

The problems installers run into with Rachio and Home Assistant — and how a managed setup prevents them.

Cloud apps bolted onto dumb timers

Many consumer sprinkler controllers only work through the manufacturer's cloud. If the service is discontinued or paywalled, the hardware is stranded. Rachio is deployed for its local control path, which keeps working regardless.

Weak wireless where the controller lives

Controllers get mounted in garages and utility rooms at the edge of wireless coverage. Dropped connections make zones show unavailable and schedules unreliable until coverage is fixed.

Valve wiring surprises on retrofit

Swapping an old timer for Rachio means re-landing zone commons, master valve, and rain sensor wires. Mislabeled or shared wires cause zones that never fire or fire in pairs.

A stuck valve waters all night

A failed solenoid or a lost stop command can leave a zone running for hours. Without runtime monitoring and alerts, the first sign is a flooded lawn or a water bill.
