Update (5/16/19): Good news: Google decided not to summarily end Works with Nest; rather, it plans to keep the program in place, but gradually bring the same functionality to Works with Google Assistant. Here's Google's statement, and here is our updated guide on the devices affected by the Works with Nest program changes.
At this year’s Google I/O conference, the company made a few strategic moves surrounding its smart-home products. For one thing, the tech giant is rebranding everything under the Nest umbrella, so that Google's security cameras, smart smoke detectors and smart displays will all have Nest in their names.
At the same time, the company has announced that it’s ending the Works With Nest program, which allowed smart-home device makers to integrate Nest products with their own gadgets in interesting and very helpful ways. For example: If a Nest Protect detected smoke or carbon monoxide, a Works With Nest integration could automatically turn on your Philips Hue- or Lutron-controlled smart lights. That’s a real safety feature that will no longer exist on September 1.
Other great things you won’t be able to do in a few months? Control your Nest thermostat from a Harmony remote, or have your lights turn off automatically when you leave the house.
Google’s justification for ending the Works With Nest program is that it will keep users’ data more private, as third parties will no longer be able to directly access or control Nest devices. That’s certainly understandable. I’m not sure I want any old smart-home device to know when I’m home and when I’m not. But more to the point, the company wants to funnel everything through Google Assistant and keep that data for itself — and also wants to know when partners’ devices are being used.
Moreover, the company's plan to end Works With Nest seems abrupt and capricious, especially to the companies that were a part of the program.
“Like other Nest partners, we received no prior notice and have just learned about this from Google's public announcement,” wrote Aaron Emigh, the CEO of Brilliant, which makes a smart touchscreen that replaces a light switch and through which you could adjust the temperature of a Nest thermostat. “We are working with Google to see if there is any way to keep Nest thermostats working in the future. So far, every indication is that they are inflexible on this score.”
Moreover, there’s nothing in place at the moment to replace this functionality. The ultimate goal of the smart-home category is not to have voice assistants everywhere, ready to react to our commands (although that’s inevitable), but instead to have devices that react automatically, based on what we’re doing.
“They’re putting their customers through an unnecessarily rough transition,” says Avi Greengart of the analyst firm Techsponential. Far better, he says, would have been for Google to quietly brief some of its major partners like Lutron and Control4 beforehand, and have everything ready to go before the Works With Nest program ended.
One of the reasons I liked the Nest thermostat is that I could tie its Home and Away statuses to other devices. For example, if the Nest went into Away mode because it didn’t detect my presence, my lights would automatically turn off and enter a mode that made it look like someone was home. I can’t do that anymore.
Currently, you can only use Google Assistant to create routines that activate at a specified time, or when you say a phrase. For example, I could connect both the Nest and the lights to a Google Assistant routine, but then I’d have to say, “Hey Google, I’m leaving,” every time I walked out the door. Not as magical.
Greengart says that Google’s actions are just reinforcing a trend that’s already occurring within the smart-home space: Google and Amazon are creating competing ecosystems that won’t work with each other. For example, Ring cameras and doorbells (owned by Amazon) cannot be added as smart home devices to Google Assistant. And good luck trying to watch YouTube (owned by Google) on an Amazon Echo Show. “Unless Google and Amazon have a real detente, consumers are going to have to choose between the two,” he said.
Hopefully, Google will expand the capabilities of its Works With Google Assistant program before Works with Nest ends. Until then, if you want to create a smarter smart home, I recommend using a smart home hub, like the Samsung SmartThings. Which, of course, doesn’t work with Nest products.
