The Netro Smart Sprinkler Controller takes a minimalist approach to smart irrigation and is built to retrofit an existing system. Reviewed points to a simple setup process and effective use of local weather data, which both optimizes watering and keeps schedules in regulatory compliance. It connects over 2.4GHz Wi-Fi and works with Amazon Echo and Google Home. The functionality is straightforward, though some reviewers saw the 6-zone or 12-zone configurations as limiting for smaller irrigation setups. Homeowners after a no-frills smart irrigation solution will like it more than anyone hunting for extensive customization.
Full review
A 5.7-inch square box with no buttons
The Sprite is a 5.7 by 5.7 inch plastic square, 1.2 inches deep, with a magnetic lid and no controls on the body at all. Every function lives in the phone app, which keeps the hardware cheap and clean but means there is no way to start a zone or check status without a handset. Owners in windy areas have reported the magnetic lid working loose. Power is standard 24VAC irrigation wiring, so it drops onto an existing valve loom.
Indoor-rated, so an outdoor install needs a case
The controller is rated for indoor mounting, as Reviewed notes. Putting it in a garage or utility room is the intended installation; mounting it at the valve box outdoors means buying the optional weatherproof enclosure, which adds cost the sticker price does not show. Wi-Fi is 2.4GHz only, which is normal for irrigation gear but worth checking against a mesh network that hides the band. Setup runs about an hour for a straightforward retrofit.
Local weather data drives the schedule
Scheduling is weather-aware: the controller pulls local forecast and rainfall data and shortens or skips cycles accordingly, and it tracks municipal watering restrictions so the schedule stays legal when a district changes its rules. Reviewed rates it well on that basis. The catch is that the intelligence lives in the cloud, so an internet outage leaves the controller running its last known schedule rather than adapting to the weather.
Six or 12 zones, and no simultaneous watering
Netro sells the Sprite in 6-zone and 12-zone versions only, which is generous for a small yard and awkward for anyone with three or four valves who is paying for capacity they will never wire up. Zones run one at a time; there is no grouping and no simultaneous operation, so a large property with many short cycles takes longer to get through than it would on a controller that overlaps zones.
Cloud service with no subscription
The cloud service carries no monthly fee, which separates it from competitors that meter weather intelligence behind a subscription. Combined with the retrofit wiring and the low hardware price, that is the strongest part of the argument. Anyone who wants tactile controls, a manual override at the box, or a controller that keeps optimizing while the internet is down should look at a model with an onboard display.
Strengths
- +Connects to 2.4GHz Wi-Fi for remote operation and monitoring, per Reviewed
- +Pulls local weather data to optimize watering schedules and minimize water waste
- +Automatically updates with local government watering regulations for compliance
Watch-outs
- −Minimal physical interface with all controls via app, which may not suit all users
How it compares
The Netro Smart Sprinkler Controller (6-Zone) puts all controls in its app, where the Orbit B-hyve Indoor Smart Sprinkler Controller has on-device buttons and the Rain Bird ARC6 Smart WiFi Sprinkler Timer takes simple commands at the controller. It handles six zones like the Rain Bird, two fewer than the Orbit's eight. It also updates automatically with local government watering regulations.
