TIRED (Pros): Solar panel is a game changer. App is easy to navigate during both setup and daily use. Watering is accurate and thorough. Built-in weather intelligence helps to avoid unnecessary runs. 优点： 太阳能电池板是颠覆性的设计。App 在设置和日常使用中都非常易于操作。灌溉精准且彻底。内置的天气智能功能有助于避免不必要的喷灌。
TIRED (Cons): Distant watering can land with heavy pressure, potentially damaging plants. 缺点： 远距离喷水时水压可能过大，有损坏植物的风险。
One of the major headaches of stand-alone smart sprinklers that attach to a garden hose is that they require power to operate. Since few folks have electrical outlets in the middle of their lawns, configuring a smart sprinkler means connecting not just a hose but also a long power cable to the device, creating double the effort and double the chance for something to get chewed up by a lawn mower. The Oto Smart Sprinkler solves for this problem with solar power, which makes for not only a far more flexible installation than its smart-sprinkler competitors but also ongoing easy use. 连接花园软管的独立智能喷灌系统，其主要痛点之一就是需要外接电源才能运行。由于很少有人会在草坪中央安装电源插座，配置智能喷灌系统意味着不仅要连接水管，还要连接一根长长的电源线，这不仅增加了工作量，还让电线被割草机损坏的风险翻倍。Oto 智能喷灌系统通过太阳能供电解决了这一问题，这不仅使其安装比同类智能喷灌产品灵活得多，也让日常使用变得更加轻松。
With a strong focus on quick setup and simplicity of function, Oto provides a refreshing alternative in the smart sprinkler market. The only question: Does its useful innovation justify its blisteringly high price tag? Oto 专注于快速设置和功能简洁性，为智能喷灌市场提供了一个令人耳目一新的选择。唯一的问题是：它实用的创新是否值得其高昂的售价？

When I unboxed the Oto Smart Sprinkler for the first time, I was convinced something must be missing—perhaps even a second box with more parts? But as it turns out, the Oto really is as streamlined as it claims to be. The sprinkler measures just 16 x 12 x 4 inches and weighs about 6 pounds. Next to the similarly featured but monstrous-by-comparison Aiper IrriSense 2, the Oto is practically miniature. 当我第一次拆开 Oto 智能喷灌系统的包装时，我确信一定少了什么东西——也许还有一个装有更多零件的盒子？但事实证明，Oto 确实如其所宣称的那样精简。该喷灌器尺寸仅为 16 x 12 x 4 英寸，重量约 6 磅。与功能相似但体积庞大的 Aiper IrriSense 2 相比，Oto 简直是“迷你”级别。
Being pint-sized makes lawn irrigation even easier than expected. You can place the unit on the ground, mount it to a hardscape, or even attach it to a fence (all with the included metal bracket). If you want to play things fast and loose, you can situate it to stand freely without the bracket, though the bracket helps you ensure it’s replaced in the exact same location if it’s ever removed (such as during the winter months) for even irrigation. 小巧的尺寸让草坪灌溉比预期更简单。你可以将其放置在地面上、安装在硬质景观上，甚至固定在栅栏上（所有这些都通过随附的金属支架实现）。如果你想随性一点，也可以不使用支架让它自由站立，不过支架能确保你在移除设备（例如冬季）后，能将其放回完全相同的位置，从而保证灌溉的均匀性。
The only real placement caveat is that in order to have it operate cordlessly, the Oto requires at least three hours a day of direct sunlight to its top-mounted 2.2-watt solar panel to keep its internal 5,400-mAh battery topped up. Keep this in mind as you decide where to install your brackets—you definitely don’t want to block too much of the sun’s rays. 唯一的放置注意事项是，为了实现无线运行，Oto 每天至少需要 3 小时的直射阳光照射其顶部安装的 2.2 瓦太阳能电池板，以保持其内置的 5,400 mAh 电池电量充足。在决定安装支架的位置时请记住这一点——你肯定不希望遮挡过多的阳光。
Before taking it outside for its first use, Oto instructs you to charge the device overnight via wall power (though you could certainly just leave it in the sun for a few days instead). You’ll do this using the included power adapter with 50 feet of cable. You can also lean on the plugged-in charging option if you can’t squeeze out enough sunshine on a regular basis (albeit in that case, this irrigation solution is probably not for you). You’ll find the power cable stored inside the Oto hardware, in a large hollow space beneath the solar panel. This hollow space is intentional and isn’t used for anything more than supporting the panel above, but it’s probably best not to leave the power adapter inside permanently, as it this chamber can get rather wet. 在首次使用前，Oto 指示你通过墙壁电源为设备充电过夜（当然，你也可以直接把它放在阳光下晒几天）。你需要使用随附的带有 50 英尺线缆的电源适配器来完成此操作。如果你无法保证充足的日照，也可以依赖插电充电（尽管在这种情况下，这个灌溉方案可能并不适合你）。你会发现电源线存放在 Oto 硬件内部，位于太阳能电池板下方的一个大空腔中。这个空腔是刻意设计的，除了支撑上方的电池板外没有其他用途，但最好不要将电源适配器永久留在里面，因为这个腔体可能会变得相当潮湿。
The Oto can throw water up to a distance of 40 feet in a 360-degree radius of the device, which equates to a maximum of 5,000 square feet of coverage, enough for a sizable lawn. (That’s about on par with Aiper.) The hose connector on the side of the device is easy to work with and secure; I experienced no leaks at all when connecting it to a standard garden hose. A 50-foot maximum length for your hose is specified to ensure water pressure remains sufficient. Oto 的喷水距离可达 40 英尺，覆盖设备周围 360 度的范围，最大覆盖面积为 5,000 平方英尺，足以覆盖相当大的草坪。（这与 Aiper 的水平相当。）设备侧面的软管接口易于操作且稳固；我在连接标准花园软管时完全没有遇到漏水问题。建议软管最大长度不超过 50 英尺，以确保水压充足。

Just about everything on the Oto happens via its app (though there’s a manual switch on top of the device you can use to speed up a run that’s pending in the app). That app sets up via a 2.4-GHz Wi-Fi connection to your home network, so you’ll need to make sure your yard has effective wireless coverage. Oto 的几乎所有操作都通过其 App 完成（尽管设备顶部有一个手动开关，可用于加速 App 中待处理的喷灌任务）。该 App 通过 2.4-GHz Wi-Fi 连接到你的家庭网络，因此你需要确保你的院子有有效的无线覆盖。
Once configured, setup proceeds much like the Aiper and pricier Irrigreen apps: You create a zone, then use the app to define its boundaries. Similar to the aforementioned systems, Oto’s sprinkler is designed for precision watering, firing water in a beam in a single direction instead of a wide spray. That said, Oto’s spray is comparably narrow, only hitting a single, designated patch instead of producing a two-dimensional curtain of water like Irrigreen’s “water printing” system. You get a nice preview of this as you set the boundaries of your yard. 配置完成后，设置过程与 Aiper 和更昂贵的 Irrigreen App 非常相似：你创建一个区域，然后使用 App 定义其边界。与上述系统类似，Oto 的喷灌器专为精准灌溉而设计，以单束水流向一个方向喷射，而不是大范围喷洒。话虽如此，Oto 的喷射范围相对较窄，只针对指定的单一区域，而不是像 Irrigreen 的“水打印”系统那样产生二维水幕。在设置院子边界时，你可以很好地预览到这一点。
Like its competitors, Oto lets you set each zone as a spot (for watering a single tree, perhaps), a line (for a flowerbed), or a 2-D area (for a yard). I tested all of these modes but spent most of my time working with area zones, which are the most complex option. When defining an area zone, I found Oto’s system to be virtually identical to that of Irrigreen and Aiper, though ever so slightly slower to respond to commands. Even so, it’s very easy to use: A simple interface lets you drop points around the sprinkler to define the boundaries of the zone. When you’ve made a full circle around the sprinkler, the area is complete. 像其竞争对手一样，Oto 允许你将每个区域设置为点（例如为一棵树浇水）、线（用于花坛）或二维区域（用于草坪）。我测试了所有这些模式，但大部分时间都在使用区域模式，这是最复杂的选项。在定义区域时，我发现 Oto 的系统与 Irrigreen 和 Aiper 几乎完全相同，尽管对指令的响应速度稍慢一些。即便如此，它也非常易于使用：简单的界面允许你在喷灌器周围放置点来定义区域边界。当你绕着喷灌器画完一个完整的圆圈后，区域设置即告完成。
Once configured, you can assign each zone a schedule, with copious options available around which days to water (odd days, even days, select days of the week, every day), and designate a start time (though there is no tying time to sundown or sunrise). Each schedule also gets a weekly watering limit (in inches of depth), which you’ll then parse out over each week’s watering runs. Weather intelligence features let you elect to skip watering if your zip code receives measurable rainfall or if winds are high. 配置完成后，你可以为每个区域分配一个时间表，并有丰富的选项来选择浇水日期（单日、双日、每周特定日期、每天），并指定开始时间（尽管无法与日落或日出时间挂钩）。每个时间表还有一个每周浇水限制（以英寸深度为单位），然后你会将其分配到每周的浇水任务中。天气智能功能允许你选择在邮编区域出现可测量的降雨或风力过大时跳过浇水。
