What's the difference between 'works with' Alexa and Google Assistant and built-in
Building a smart home isn't as simple as the manufacturers might have you believe
Amazon Alexa, Google Assistant and Apple's Siri are the three biggest personal assistants right now. Powered by artificial intelligence and always listening, they can answer questions, play music, help organize our lives, and control our smart homes.
These assistants live in devices sold by their manufacturers, but are increasingly appearing in products sold by other companies, where they do not always offer the same intelligence or set of features.
Along with this, it is important to remember that a huge range of smart home devices work with each of the three main assistants - but this doesn't necessarily mean that every assistant has absolute control over a smart home device. For example, Alexa works with Philips Hue smart lights, but it can't control them in every way that the Hue smartphone app can.
Key to this article is the difference between a device 'working with' an assistant like Siri and Alexa, and a product which has an assistant 'built in'. There are already lots of the former, and in 2018 we're going to see growing numbers of the latter.
Devices with the full Alexa experience baked in
First, let's list every device that offers every Alexa feature. In other words, those made by Amazon. They are:
- Amazon Echo
- Amazon Echo Plus
- Amazon Echo Dot
- Amazon Echo Dot with clock
- Amazon Echo Dot Kids
- Amazon Echo Dot Kids with clock
- Amazon Echo Spot
- Amazon Echo Show (5, 8, 10, and 15-inch screens)
- Amazon Echo Pop smart speaker
- Amazon Echo Hub
- Amazon Echo Studio
The Echo, Plus, Dot, Studio, and Pop communicate with Alexa via sound only; you talk, and she replies via a speaker. The Spot, Show, and Echo Hub do this, too, but also have screens to show video content and text to accompany what Alexa says.
Amazon used to sell a Bluetooth speaker called the Tap, which had Alexa but did not constantly listen for the 'Alexa' hotword like the Echo range. Instead, the Tap required a press (or a tap) to make Alexa listen. This is because the Tap is battery-powered, and having it always listen for the wake word would be a waste of battery.
Amazon's Fire TV streaming stick also uses Alexa. Still, here, the assistant is tailored to search for Amazon Prime Video content, navigate the Fire TV interface, and provide information on the movie you are watching.
You can learn more about the smart devices that work with Amazon Alexa-enabled devices by visiting The GearBrain; our compatibility find an engine for connected devices. The GearBrain has a page called What Works with Amazon Alexa, which will show you all the gadgets that you can control by voice using an Echo, Echo Dot, or any Amazon Alexa-enabled device or appliance.
Devices with the full Google Assistant experience baked in
It is a similar story at Google, where its own devices offer the full Assistant experience. Still, the product catalog is more diverse and features Chromecast and Android smartphones. These include:
- Google Home
- Google Home Mini
- Google Home Max
- Nest Hub
- Nest Hub Max
- Nest Mini
- Nest Audio
- Chromecast with Google TV
- Google Pixel 2 and 2 XL
- Most Android smartphones
Devices with Alexa, but with some features missing
Here is a list of devices which have Alexa, but aren't made by Amazon.
- Lenovo Smart Tab M10 Plus, FHD Android Tablet
- Lenovo Smart Tab P10 10.1” Android Tablet
- Lenovo Smart Clock with Alexa
- Sonos Era 100 & 300
- Ecobee 4 smart home thermostat
- Huawei Mate 9 smartphone
- Vobot alarm clock
- Sonos One
- Logitech ZeroTouch smartphone car mount
- Guess Connect smartwatches
- Cowin DiDa Bluetooth speaker
- Garmin Speak car navigation system.
- iDevices light switches
- C by GE Sol smart lamp
- LG Smart Instaview Refrigerator
Now, things start to get complicated. These can be bought, plugged in, and used like an Echo speaker - but some features are missing. Alexa's skill set varies case by case, making it difficult to know exactly what you are getting into.
For example, where Echo devices can drop in on each other and make phone calls to other Echo products - acting like a home intercom system — the Sonos One cannot. It also, somewhat bizarrely, given its focus on music - cannot wake you up with a radio station. It can play radio on command and be used as an alarm, but unfortunately, these two cannot be combined.
All it would take is a software update from Amazon and/or Sonos, but we feel Amazon would like to keep some features exclusive to its own Echo family. The One also can't join in with Alexa Routines, so you can't configure it to read out your morning news briefing without first asking out loud.
Devices with Google Assistant, but with some features missing
It is a similar story with Google Assistant, which appears in stripped-down form on smartwatches running Android Wear 2.0 or later, some Sony Bravia smart TVs, and soon as a part of Android Auto.
Google Assistant is also coming to the Sonos One with a software update but for now it isn't known if this will turn the speaker into a better-sounding Google Home, or if some features will be lost.
You can learn more about the smart devices that work with Google Assistant-enabled devices by visiting The GearBrain, our compatibility checker for connected devices. The GearBrain has a page called Here's What Works with Google Home and The Google Home Mini , which will show you all the gadgets that you can control by voice using a Google Home, Google Home Mini, or Google Assistant-enabled device or appliance.
Apple Siri
You'd think things would be simpler with Apple and Siri, but that isn't necessarily the case. Siri on the iPhone, iPad and iPod Touch is the real deal and includes every Siri feature.
However, Siri on the Mac cannot operate HomeKit devices like smart lights, Siri on the Apple TV cannot search the web, and Siri on the new HomePod smart speaker cannot access your calendar or email, provide help with navigation, or a whole host of other things that have worked for years on your iPhone.
Finally, because of Apple's walled-garden approach to inclusivity, only Apple devices run Siri.
What about products that 'work with' Alexa, Google and Siri?
Now that we have explained the different degrees of 'baked in' available, we can turn to explaining what it means when a device 'works with' your personal assistant of choice.
Many, many smart home gadgets and appliances now 'work with' Amazon Alexa, Google Assistant and Apple's HomeKit system, which in turn is controlled by either the Home app on your iPhone, or by speaking to Siri.
Such devices include, but are by no means limited to:
- Smart plugs from TP-Link, iHome, Samsung SmartThings, Belkin and more
- Smart lights by Philips, Ikea, TP-Link, GE, Lifx and more
- Door locks by August
- Robotic vacuum cleaners by iRobot
- Thermostats, cameras and smoke alarms by Nest
The best example we could find to explain this is the Philips Hue smart light starter kit, which includes three bulbs, a controller, and a hub for connecting to your Wi-Fi router. On the box there are icons which state: "Works with Amazon Alexa", "Works with Apple HomeKit" and "Works with the Google Assistant".
Once set up via the Philips Hue app, these lights can be controlled via voice commands delivered to Alexa, Siri, and Google Assistant. Alternatively, you can use their respective smartphone applications or the Philips app itself (plus a range of third-party Hue alternatives).
After adding the Hue lights to your Alexa, Google Assistant, or Apple HomeKit apps, you can speak to turn the bulbs on and off, adjust their brightness, and change their colors.
However, more advanced controls are not possible. For example, you can ask Alexa to "make the lounge yellow," but you cannot change the 'scene' of a Hue light by asking the assistants to "switch the bedroom scene to Savannah Sunset", and you cannot ask for the light to be switched on or off at a certain time. To access these features, you need to use the Hue app.
Summary
We appreciate that this is a lot to take in at once. While it is good news that the smart home landscape is growing quickly—thanks to the popularity of Alexa and Google Assistant—it also means consumers are often pulled in several directions at once.
There is no global, universal standard for smart home devices to comply with, so any product you buy will likely work slightly differently with each of the three main assistants. Some will say the new Matter protocol will solve this problem, but you still need to have a hub to control your smart devices in one app. So, while Alexa and Google Assistant have the basics covered—turning lights on and changing their color—they often cannot match the features offered by an app produced by the device's own manufacturer.
Looking out for the 'works with' icons is key, and buying products with several—like Hue lights—is likely your best approach to building a smart home that is both future-proof and easy to operate. The good news is that, with all of these devices connected to the internet, software updates will likely bring new features and improved control and take us a step closer to the assistant-agnostic smart home we all want.
