Apple HomeKit是主要的智能家居平台之一，但由于兼容设备的范围相对狭窄以及远程控制它所需的复杂设置，它是迄今为止最不受欢迎的。但是Apple粉丝，以及HomeKit粉丝，是一群顽固的人。
那些喜欢苹果(Apple)生态系统的人真的很(really)喜欢它，这导致了与HomeKit 兼容的设备(HomeKit-compatible devices)的缓慢但稳定的增长。虽然它们仍然有些难以获得，但还是有希望的。
然而，智能恒温器是HomeKit(HomeKit)最难找到的一些智能设备。只有两家公司能够制造出普通人听说过的最好的智能恒温器：ecobee 和Nest。
坏消息是：没有Nest恒温器与HomeKit兼容，也不是所有的 ecobee 恒温器都兼容。好消息？还有其他选择。
ecobee4 智能恒温器(ecobee4 Smart Thermostat)(ecobee4 Smart Thermostat)
ecobee4智能恒温器(Smart Thermostat)是当今市场上最好的兼容 HomeKit 的智能恒温器。该设备声称每年可为房主节省多达 23% 的供暖和制冷成本，并在不到两年的时间内收回成本。
它不仅可以与HomeKit一起使用，还可以连接到三星 SmartThings(Samsung SmartThings)、IFTTT，并内置了Alexa 。
ecobee4 通过您放置在不同房间的一系列传感器进行操作。您将传感器放置在最常用的房间：客厅、餐厅、卧室等。这些传感器跟踪房间的温度及其占用情况，并调整加热/冷却以保持整个家庭的平衡。
当您最初购买 ecobee4 时，它包括一个房间传感器，但可以单独购买额外的 2 包传感器。
另一个好处是，ecobee4 可以安装在没有C 线(C-wire)的家庭中，这是过去阻止智能恒温器安装的一个因素。内置的Alexa功能意味着您可以执行HomeKit可能无法执行的任务，前提是您在恒温器的可听范围内。ecobee 应用程序可在Android和 iOS 上使用，但如果您是HomeKit的死忠用户，那么假设您也有 iPhone 是安全的。
售价 249 美元的 ecobee4 也不会破产。在选择有限的情况下，这是最好的全能选择。可以购买升级版的 ecobee4，称为带有语音控制的 ecobee 智能恒温器( ecobee Smart Thermostat with Voice Control)。它是 ecobee4 的升级版，目前更便宜，并提供智能开关。
ecobee3 Lite 智能恒温器(ecobee3 Lite Smart Thermostat)(ecobee3 Lite Smart Thermostat)
正如您可能从名称中猜到的那样，ecobee3 Lite是更现代的 ecobee4 的先前迭代。它的运行方式与新版本的运行方式大致相同，只是减去了一些关键特性。
ecobee3 没有内置Alexa ，也没有购买时包含房间传感器。(Alexa)但是，它仍然兼容Apple HomeKit、Alexa、三星 SmartThings(Samsung SmartThings)，甚至是Microsoft Cortana等不常用的助手。
ecobee3 也可以在没有C 线(C-wire)的家庭中使用。安装(Installation)平均需要半小时，不需要专业帮助。总而言之，这是一笔不错的投资，尤其是如果您不关心Alexa的话。
另一方面，您可能想知道为什么愿意购买旧型号。答案很简单：它更实惠。ecobee3 的售价约为 140 美元，比新版本低 60 美元。如果您住在小型住宅或公寓中，则无需额外的房间传感器。
毕竟，恒温器不一定要有它们——它们只是帮助它在更大的家庭中更有效地运行。
霍尼韦尔歌词 T5(Honeywell Lyric T5)(Honeywell Lyric T5)
Honeywell Lyric T5的价格比 ecobee3 还要低。它的价格为 120 美元，比此列表中的其他两个选项中的任何一个都更实惠。
您可以通过WiFi控制(WiFi)Honeywell Lyric并设置 7 天的时间表，以确保您的家在您想要的时候正是您想要的温度。由于与HomeKit的兼容性 ，您还可以通过Siri控制(Siri)Honeywell Lyric 。
关于这款恒温器，有一些有趣的功能值得一提。首先(First)是“自适应恢复”设置。它了解达到指定温度需要多长时间并自动开始调整，以便在设定的时间内达到该温度。当您的过滤器需要更换或传感器检测到极端温度变化时，它还会向您发送推送通知。
Honeywell Lyric还利用地理围栏来调节温度。如果您在家时有首选温度，并且您的手机处于指定范围内，Lyric将自动开始调整，以便在您到达时达到该温度。
虽然价格实惠，但有一点需要注意。大约一年半前，霍尼韦尔(Honeywell)将他们的智能家居产品分拆成一家名为Resideo的公司，因此(Resideo)霍尼韦尔 Lyric T5(Honeywell Lyric T5)可能会在很长一段时间内无法使用。
还有一些其他品牌可以与HomeKit一起使用，但没有一个具有这三款设备的功能。一些报告指出，由于来自用户群的请求数量， Nest可能会在未来添加HomeKit兼容性，但这还没有得到证实——也不是什么让你屏住呼吸的事情。
相反，请看一下Apple HomeKit的最佳智能恒温器的这三个选择之一。它们代表三个不同的定价层，但三个中的任何一个都是坚固的智能恒温器。
The 3 Best HomeKit Compatible Smart Thermostats
Apple HomeKit is one of the major smart home platforms, but it’s by far the least popular due to the relatively narrow range of compatible devices and the complicated setup required to control it remotely. But Apple fans, and consequently HomeKit fans, are a stubborn bunch.
Those that like the Apple ecosystem really like it, which has led to the slow but steady growth of HomeKit-compatible devices. While they can still be somewhat hard to come by, there’s hope.
Smart thermostats are some of the hardest smart devices to find for HomeKit, however. There are only two companies that make the best smart thermostats the average person will have heard of: ecobee and Nest.
Here’s the bad news: no Nest thermostat is compatible with HomeKit, and not all ecobee thermostats are. The good news? There are other options.
The ecobee4 Smart Thermostat is the best HomeKit-compatible smart thermostat on the market today. This device claims to save homeowners as much as 23% annually on heating and cooling costs and pay for itself in just under two years.
Not only does it work with HomeKit, but it also connects to Samsung SmartThings, IFTTT, and has Alexa built-in.
The ecobee4 operates through a series of sensors you place in different rooms. You place the sensors in the most commonly used rooms: the living room, dining room, bedroom, etc. These sensors track the temperature of the room and its occupancy and adjust the heating/cooling to keep the entire home balanced.
When you initially purchase the ecobee4, it includes one room sensor, but additional 2-packs of sensors can be purchased separately.
Another benefit is that the ecobee4 can be installed in homes without a C-wire, a factor that has prevented smart thermostat installation in the past. The built-in Alexa functionality means you can perform tasks that HomeKit may not be able to do, provided you are within the audible range of the thermostat. The ecobee app is available on both Android and iOS, but if you’re a die-hard HomeKit user, it’s safe to assume you have an iPhone too.
At $249, the ecobee4 isn’t going to break the bank, either. It’s the best all-around choice in a landscape of limited options. There is an upgraded version of the ecobee4 available for purchase that is dubbed the ecobee Smart Thermostat with Voice Control. It is an upgraded version of the ecobee4 and is currently less expensive and offered with a smart switch.
As you might guess from the name, the ecobee3 Lite is a previous iteration of the more modern ecobee4. It operates in much the same way as the newer versions minus a few key features.
The ecobee3 does not have Alexa built-in, nor does it include a room sensor with purchase. However, it is still compatible with Apple HomeKit, Alexa, Samsung SmartThings, and even less-used assistants like Microsoft Cortana.
The ecobee3 also works in homes without a C-wire. Installation takes an average of half an hour and does not require professional help. All in all, it’s a decent investment, especially if you don’t care about Alexa.
On the other hand, you might wonder why you would willingly purchase an older model. The answer is simple: it’s more affordable. At roughly $140, the ecobee3 is $60 less than the newer version. If you live in a small home or apartment, there is no need for additional room sensors.
The thermostat doesn’t have to have them, after all—they just help it operate more efficiently in larger homes.
At an even lower price than the ecobee3 is the Honeywell Lyric T5. At $120, it’s more affordable than either of the other two options on this list.
You can control the Honeywell Lyric through WiFi and set 7-day schedules to ensure your home is exactly the temperature you want when you want. You can also control the Honeywell Lyric through Siri due to its HomeKit compatibility.
There are a few interesting features worth mentioning about this thermostat. First is the “adaptive recovery” setting. It learns how long it takes to reach a specified temperature and automatically begins to adjust so that it achieves that temperature by a set time. It will also send you push notifications when your filter needs changing, or if the sensors detect extreme temperature changes.
The Honeywell Lyric also makes use of geofencing to adjust the temperature. If you have a preferred temperature for when you’re at home and your phone comes within a specified range, the Lyric will automatically start adjusting so that it reaches that temperature when you arrive.
While affordable, there is something to note. Honeywell spun their smart home offerings into a company called Resideo about a year and a half ago, so the Honeywell Lyric T5 may not be available for an extended period.
There are a few other brands that work with HomeKit, but none have the features of these three devices. Some reports state that Nest might add HomeKit compatibility in the future due to the number of requests from the user base, but that is not confirmed—and not something to hold your breath for.
Instead, take a look at one of these three choices of the best smart thermostats for Apple HomeKit. They represent three different pricing tiers, but any one of the three is a solid smart thermostat.
