WIIRed names Oto Smart Sprinkler top solar-powered pick amid rising garden tech costs
The $499 device eliminates the need for power cables, offering 360-degree coverage and weather-intelligence features that reviewers say justify the premium price point.
WIIRed has published a review of the Oto Smart Sprinkler, naming it the top pick for standalone smart irrigation systems. The publication praised the device’s solar-powered operation and straightforward setup, noting these features provide a significant advantage over competitors that rely on cumbersome power cables. Priced at $499, the unit positions itself between budget options and premium systems like the Irrigreen, which costs over $2,000.
The primary innovation of the Oto lies in its ability to operate cordlessly. The device is equipped with a 2.2-watt top-mounted solar panel and an internal 5,400-mAh battery. According to the review, the sprinkler requires at least three hours of direct sunlight daily to maintain a full charge, allowing for flexible installation without the risk of lawn mowers damaging power cords. If sunlight is insufficient, the unit can be charged via a wall adapter, which includes a 50-foot cable stored within the device’s hollow base.
Physically, the Oto is notably compact, measuring 16 by 12 by 4 inches and weighing approximately 6 pounds. This size is significantly smaller than competitors like the Aiper IrriSense 2. The unit offers 360-degree coverage with a range of up to 40 feet, equating to a maximum coverage area of 5,000 square feet. It connects to a standard garden hose, with a maximum hose length of 50 feet recommended to maintain adequate water pressure.
Control is managed entirely through a mobile app that connects via 2.4-GHz Wi-Fi. Users can define zones as spots, lines, or two-dimensional areas, with the app allowing for precise scheduling and weekly watering limits based on depth in inches. The system also features weather intelligence, automatically skipping watering cycles if measurable rainfall or high winds are detected in the user’s area. The watering mechanism uses a narrow beam that moves in circular arcs, expanding its range with each swipe, followed by clean-up runs to ensure even coverage.
The review concluded that the Oto performed as expected during testing, with the battery remaining fully charged via solar power alone. While the price is high, WIIRed noted that the innovation and ease of use justify the cost, predicting a potential price war in the smart sprinkler market as summer approaches. For now, the Oto stands as the recommended choice for consumers seeking a standalone, solar-powered irrigation solution.
