I Let Alexa+ and Gemini Power My Smart Home, and They Were Both Great

The AI chatbots are coming for your smart home. Both Alexa+ and Gemini for Home are now rolling out to users who've opted in to the upgrades, replacing standard Alexa and Google Assistant, respectively.

Once you get access, they'll do everything we've become familiar with from these next-gen AI assistants—natural language conversations, complex queries and responses, various hallucinations—while retaining all the previous smart-home functionality, whether that's turning off lights or checking in on video doorbells.

I got access to these two upgrades within the space of a week, giving me the opportunity to test them against each other. With an Amazon Echo Show, a Google Nest Hub, and a selection of Philips Hue smart lights, I got to work.

Upgrading to Alexa+ and Gemini for Home

Upgrades to both Alexa+ and Gemini for Home appear in the relevant apps on your phone. You'll be prompted to set up the new AI assistant, then taken through a few basic configuration steps (like choosing a voice for the AI). With that done, it's a case of simply saying "hey Alexa" or "hey Google" to the app on your phone or one of the smart devices you've got, and talking.

Alexa+ does have one advantage in terms of its web app: If you use it via a browser, you get a smart home controls section you can switch to. Gemini on the web won't understand or implement any smart-home-related commands you give it, though rather confusingly it does sync chats you've had on your phone app, which will include these commands if you look back at them.

Both these AI apps only offer the basics for free when it comes to smart home controls (switching things on and off). With Alexa+, if you want the full conversational AI experience, it's going to cost you $19.99 per month—though it's also available as part of Amazon Prime, which is $14.99 a month. Note that this is separate from any Ring subscriptions you need to archive your video recordings.

With Gemini for Home, the conversational AI is paywalled, as is the video recording history. You can opt to pay $10 or $20 a month, depending on how much video history you want (these plans replace the old Nest Aware ones). The higher tier also gets you AI-powered event descriptions and summaries for what's happening in any recorded video clips ("a delivery driver arrived at 1pm" and so on), and if you already pay Google $19.99 or more a month for one of the other Gemini AI plans, you get Gemini for Home included.

How Alexa+ and Gemini for Home stack up against each other

With the AIs up and running, I asked about which days I'd need an umbrella. While both assistants accurately understood the question and told me the weather forecast for the week, I preferred Gemini's answer: It was more comprehensive, and actually answered the question about the umbrella for each day (Alexa+ just gave me the chance of rain each day, and left me to make my own mind up about an umbrella, though the graphics were nicer).

I requested some tips on bathroom cleaning, and both Alexa+ and Gemini for Home gave me answers that were informed and free from errors (as far as I could tell). They both accurately summarized several movies for me without a hitch, too, though Alexa+ was more cautious when it came to spoilers.

These are the type of questions and prompts you can put through Alexa+ and Gemini—but it's the smart home integration I was most interested in looking at. When you update to Alexa+ or Gemini for Home, all of your existing devices with smart assistant access get the upgrade too.

How Alexa+ and Google for Home integrate with smart home devices

It's in controlling your smart home devices where things get trickier for Alexa+ and Gemini for Home, because they first have to recognize that you're providing a simple command—and then they must carry it out, rather than launching into a long answer about the features of smart lights or the best affordable smart cameras for families.

I was expecting a few mistakes and bugs here, but was pleasantly surprised by both AIs: I was able to easily change my smart-light settings with my voice, including their color and their brightness, as well as whether or not they were switched on.

Scheduled actions worked well, too: I got Gemini for Home to turn on my smart lights at a certain time, and told Alexa+ to turn them back off at a later time, and my instructions were followed exactly. You can set up these routines to repeat across certain time periods too, and they get saved in the app if you need to make edits.

If you've got an Amazon or Google smart display, you can set up widgets for your smart home devices, and control them with a few taps. Both my Echo Show and my Nest Hub let me control light status, color, and brightness from the screen, and both worked flawlessly with barely any lag at all.

I also tested reminders and timers—two other features you're likely to want to access through your smart speakers or smart displays. Again, both Alexa+ and Gemini for Home did what they were told, correctly recognizing a direct command rather than a more complex AI prompt, and carrying out the instructions.

With no smart home cameras or doorbells installed, I couldn't test out the video features offered by these AIs. Anecdotal evidence suggests they can be a bit hit-or-miss when identifying what's going on in a clip and summarizing it for you—so you shouldn't always expect them to be perfectly accurate. In general, I found Alexa+ and Gemini for Home to be reliable, smart, and useful.
