Amazon says it will acquire eero, the San Francisco-based maker of mesh home WiFi routers.

The deal strengthens Amazon in the smart home arena, an area Amazon has been very focused on in recent years. Eero’s routers use multiple access points that work together to blanket a home with WiFi coverage.

With flexible configurations for different sizes and shapes of home, the company’s goal is to eliminate dead spots. Amazon appears interested in eero’s ability to better connect smart home devices.

“We are incredibly impressed with the eero team and how quickly they invented a WiFi solution that makes connected devices just work,” Dave Limp, senior vice president of of Amazon Devices and Services said in a statement. “We have a shared vision that the smart home experience can get even easier, and we’re committed to continue innovating on behalf of customers.”

Financial terms of the deal were not disclosed.

Amazon has made some major smart home deals in the recent past. The most notable is Ring, the smart doorbell maker that Amazon acquired last year. Since the acquisition, Ring has put out a number of other security-focused devices to round out its offerings.

Amazon’s smart home focused is centered around the digital brain Alexa, and making it more simple for users. Smart home systems are notoriously complex to set up, and the interplay of devices can put a lot of strain on home WiFi systems. Eero aims to bring enterprise-grade mesh systems that create stronger coverage to the home, making it easier to run a bunch of smart devices at the same time.

There’s also a potential tie-in to another growing Amazon service. The company recently expanded Key by Amazon, the program that lets delivery drives slip items inside homes or garages via smart locks. These are sometimes in areas that could be soft spots for WiFi coverage, but the addition to eero to Amazon’s lineup could represent a solution for that issue.

This is Amazon’s third acquisition of the year so far, with the first two coming from its Amazon Web Services cloud division: TSO Logic, a Vancouver B.C. startup working on cloud spending analysis; and CloudEndure, a disaster-recovery services company based in Israel. Financial terms of those deals were not disclosed.
