当谈到智能恒温器时，有一小部分可以选择，但是最突出的三个是Nest，Ecobee4和Honeywell Lyric Round。 我们已经尝试了这三个，看看哪一个具有优势，并有哪些不同的特征。
当谈到智能恒温器时，最受欢迎的选择之一就是Nest Thermostat（250美元），它是原始iPod设计师Tony Fadell独特设计的产品（Nest的旋转轮让人想起）。 但是，最终的功能是能够学习你的习惯，并自动改变恒温器，以便你不用手忙脚乱的使用它。
如果Nest Thermostat的价格吓到你了，那么你可以拿到成本较低的版本，叫做Nest Thermostat E.它是用塑料做成的，而不是金属制成的，显示效果不怎么样，只有169美元。 你也可能从你的电力公司获得部分购买款的返还支持。
像Nest Thermostat一样，Ecobee4也有一个名叫Ecobee3 Lite的小弟弟。 它没有内置Alexa，也没有配备遥控器，但价格仅为169美元。
The Honeywell Lyric Round（200美元）并不像上述两种选择那样受欢迎，而是霍尼韦尔（Honeywell）试图打造一款时尚而时尚的智能恒温器。 它有一个像Nest这样熟悉的圆形，甚至有一个类似的旋转轮 – 虽然它不如Nest的流体滚动环那样有触觉。

为您的A / C或热设定一个时间表
Nest 没有苹果IOS（APPLE）的 HomeKit 应用程序
如上所述，Ecobee4不仅是一个智能恒温器，它也是一个回声点 – 它带有一个麦克风，扬声器和Alexa全部内置给你的完整体验，分开的部分你通常必须另外购买。
在宏伟计划中，这不是什么大问题，因为你可以以50美元的价格购买Echo Dot（甚至在用过的市场上也可以买到更便宜的），但是节省了50美元， 你在首先购买也是一个非常甜美的交易。
我发现Nest Thermostat是最容易安装的，主要得益于Nest网站上的兼容性检查工具，您可以在其中输入恒温器设置的电线，Nest会告诉您每根电线在Nest Thermostat上的位置 本身。 之后，这只是一个插电线的问题。
此外，Nest可以完全在它本身内就可完成设置，而Lyric Round需要附带的应用程序来设置。 Ecobee4像Nest一样能够在它本身内就可完成设置，由于它的触摸屏显示，它比Nest更容易。
然而，Ecobee4的安装是三个中最难的，因为它可能需要一个必须安装在炉子电路板上的功率扩展器套件。 这不难做到，Ecobee的支持完美地引导了我，但是有一点让人烦恼，不得不跳过额外的环节。 幸运的是，不是每个人都需要安装这个工具包，这取决于你所拥有的HVAC系统。
然而，Ecobee4有一个无线传感器，你可以放在任何地方。 在这种情况下，在温度不同的地方，最好放置在楼上。 从那里，你可以告诉你的Ecobee4使用楼上的传感器来判断A / C或热量是否在运行。
最后，我们不能停止对Nest的想象。 虽然没有HomeKit或远程传感器，但却是最简单的智能恒温器。 该应用程序是非常好的，单位本身的滚动环，使它简单，易于操作。 用户界面看起来很简单。
The Lyric Round当然也不是一个糟糕的智能温控器，但它并不像Nest和Ecobee4有那么多特点。
总的来说，霍尼韦尔Lyric根本就不是一个好的体验。 这个应用程序相当麻烦 – 在我保存并关闭它之后，一些更改的设置恢复为默认设置，并且在使用恒温器的前几天内收到了几条错误消息。 另外，我不得不重新连接到Wi-Fi，并且最初几次它不能连接。
说实话，我完全不能推荐这个恒温器 – 它可能比其他两个便宜50美元，但是你真的更好用另外两个选项之一。
Nest vs. Ecobee3 vs. Honeywell Lyric: Which Smart Thermostat Should You Buy?
by Craig Lloyd
Nest vs. Ecobee3 vs. Honeywell Lyric: Which Smart Thermostat is better?
When it comes to smart thermostats, there’s a handful to choose from, but the big three that stand out are the Nest, Ecobee4, and Honeywell Lyric Round. We’ve tried out all three to see which one has the upper edge, and where their features differ.
Can a Smart Thermostat Actually Save You Money?
Each of these three smart thermostats is unique in its own way, so before we dive in and discuss the similarities and differences between them, here’s a brief overview of the Nest, Ecobee4, and the Lyric Round.
One of the more popular options when it comes to smart thermostats is the Nest Thermostat ($250), which sports a unique design from Tony Fadell, the designer of the original iPod (which the Nest is mildly reminiscent of with its spinning wheel). It’s ultimate feature, though, is the ability to learn your habits and automatically change the thermostat so that you eventually don’t have to mess with it at all.
How to Get the Most Out of Your Nest Thermostat
Its user interface is also very user-friendly, and perhaps the easiest smart thermostat to install and use out of the three.
If the price of the Nest Thermostat scares you, you can grab the lower-cost version, called the Nest Thermostat E. It’s made out of plastic instead of metal, and the display isn’t quite as grand, but it’s only $169. You can also likely get rebates from your power company.
The Ecobee4 ($250) is the only smart thermostat that we know of that has a touch screen, so if you know how to use a smartphone, then controlling this thermostat will be a breeze. It also has the biggest screen out of the three thermostats, giving room for plenty of information to appear without crowding the display.
How to Get the Most Out of Your Ecobee Smart Thermostat
The Ecobee4 also comes with a remote sensor that you can place in another room, so if you have a larger house with an upstairs, you can place the sensor there and have the thermostat use that sensor for regulating the temperature instead of the sensor that’s on the thermostat itself.
The biggest feature of the Ecobee4, though, is its built-in Alexa capabilities, doubling the thermostat as an Echo Dot of sorts. So if you’ve ever wanted an Echo in your living room, this is a good way to kill two birds with one stone.
And like the Nest Thermostat, the Ecobee4 also has a little brother called the Ecobee3 Lite. It doesn’t come with Alexa built in, nor does it come with a remote sensor in the box, but it’s priced at only $169.
The Honeywell Lyric Round ($200) isn’t quite as popular as the two options above, but its Honeywell’s attempt at creating a hip and sleek smart thermostat. It has a familiar round shape like the Nest, and even has a similar spin wheel—although it’s not nearly as tactile as the Nest’s fluid scroll ring.
It was also pretty easy to install, and Honeywell does a decent job of telling you where all the wires go. However, that’s where most of the pleasantries end, as the user interface is quite buggy.
It’s certainly the cheapest smart thermostat out of the three, but spending $50 more for one of the options above is probably your best bet.
What They All Have in Common
Before we get into the nitty gritty, we thought it’d be a good idea to go over what all three of these smart thermostats can do. They have their major differences, yes, but they all share the basic features of a good smart thermostat, including:
iOS and Android support
Control your thermostat away from home using your phone
Set a schedule for your A/C or heat
Geofencing and motion detection, so it knows when you’re home (Note: The Ecobee4 uses IFTTT for geofencing) and can turn on the display when you walk by
Amazon Echo support, so you can adjust the temperature with your voice
Family sharing, so other household members can adjust the thermostat
Weather forecast data, so you know what’s coming
With all that in mind, let’s look at some of the standout pros (and cons) of each.
Nest Doesn’t Have HomeKit
If you’re an iOS user, HomeKit is a feature that you might want with your smarthome products, as it makes easier to control and manage them. However, the Nest Thermostat doesn’t have HomeKit, and probably will never support it.
Nest is owned by Google, and they’re a fierce competitor with Apple. While Google has brought many of its mobile apps to iOS, the chances of Nest products getting HomeKit support are slim to none.
The good news is that the Ecobee4 and the Lyric Round both have HomeKit support, so if you absolutely want HomeKit in your smart thermostat, these two are your options.
Ecobee4 Doubles As an Echo Dot
As mentioned further above, the Ecobee4 is not only a smart thermostat, but it’s also an Echo Dot of sorts—it comes with a microphone, speaker, and Alexa all built in to give you the full experience that you’d normally have to pay for separately.
In the grand scheme of things, this isn’t a huge deal, since you can just buy an Echo Dot for $50 (or even cheaper since the used market is littered with them), but saving that $50 and having one already built into something you’re buying in the first place is also a pretty sweet deal.
Nest Is the Easiest to Install
I found the Nest Thermostat to be the easiest to install, mostly thanks to the Compatibility Check tool on Nest’s website, where you can enter in the wires that your thermostat setup has and Nest will tell you where each of those wires go on the Nest Thermostat itself. After that, it’s just a matter of plugging in wires.
How to Install and Set Up the Nest Thermostat
Furthermore, setting up the Nest can be done completely on the unit itself, whereas the Lyric Round required the accompanying app to get it set up. The Ecobee4, like the Nest, was able to be set up on the unit itself, which was a bit easier than the Nest thanks to its touch screen display.
However, the Ecobee4 install was the hardest out of the three, since it likely requires a Power Extender Kit that has to be installed on the furnace’s circuit board. This wasn’t too hard to do, and Ecobee support flawlessly guided me through the process, but it was just a little annoying to have to jump through extra hoops. Luckily, not everyone needs to install the kit—it depends what HVAC system you have.
Ecobee4 Is Best for Bigger Homes
If you have a house like mine, the upstairs is always warmer than the downstairs, which can be a problem if your thermostat is downstairs. Since most thermostats use the temperature sensor on the thermostat itself, it doesn’t know what the temperature is upstairs, so it can’t adequately cool your entire house.
How to Manually Select Which Ecobee Sensor to Use
However, the Ecobee4 has a wireless remote sensor that you can place anywhere. In this case, it works best placed upstairs where the temperature differs. From there, you can tell your Ecobee4 to use the sensor upstairs in order to gauge whether the A/C or heat should be running or not.
Of course, you can simply just crank up any other thermostat to compensate for the warmer upstairs region, but the Ecobee4’s remote sensor makes it precise so that you’re not wasting more energy than necessary.
Nest Has the Best User Experience
In the end, I couldn’t stop thinking about the Nest. While it doesn’t have HomeKit or remote sensors, it was the easiest smart thermostat to use. The app is really good and the scroll ring on the unit itself makes it simple and easy to operate. The user interface just looks plain good.
Plus, all of the settings available for it are accessible right from the app, whereas a handful of settings on the Ecobee4 require you to login to the web portal.
The Lyric Round Is Too Buggy to Recommend
The Lyric Round certainly isn’t a terrible smart thermostat, but it doesn’t have quite as nearly the number of features that the Nest and Ecobee4 have.
Overall, the Honeywell Lyric simply wasn’t a good experience at all. The app is fairly buggy—some changed settings reverted back to default after I saved and closed it out, and I received several error messages within just the first few days of using the thermostat. Plus, I had to reconnect it to Wi-Fi, and the first few times it just wouldn’t connect.
To be honest, I can’t recommend this thermostat at all—it may be $50 cheaper than the other two, but you’re really better off with one of the other two options.
In the end, when it comes to choosing the best one, I think it really depends on what you want out of a smart thermostat. The Nest and the Ecobee4 are easily the two worth looking at, but if you want HomeKit or remote sensors, then the Ecobee4 is the thermostat to buy. Plus, the touch screen on the Ecobee4 makes it easier and quicker to navigate through menus than most other smart thermostats. Furthermore, if you don’t need the remote sensors of the Ecobee4, then the Ecobee3 Lite might be an even better buy at only $170.
However, the Nest has the best user interface, best app, and best experience overall, making it the right choice if you don’t really need the extra features of the Ecobee4.
