While smart device engineering has flourished in recent years, the market is still deeply fragmented, leading to consumer confusion and frustration. Looking back to 2016 (the year Amazon’s Echo Dot was released), smart product design was dominated by dozens of single-purpose products and apps. As consumers increasingly adopted Echo Dot and other voice-operated devices, integration began, enabling users to control all their devices (from multiple vendors) through a single interface. The integration trend has grown as voice hubs started including displays. Connected devices appear integrated because of this common control point, but, in practice, the devices do not communicate or interact with one another.


What are the Challenges of Smart Device Design?

The challenges going forward for any smart home product design company releasing new products or other brands entering the smart home market are:

  1. Providing deeper integration so that connected products can satisfy multiple use cases.
  2. Placing bets on which standards will gain traction in the market and which will no longer need to be supported.

With the dizzying array of competing communications standards, such as Zigbee, Z-Wave, Wi-Fi, BLE and the various ecosystems from Amazon, Google, Apple, Samsung and Comcast, along with the promise of Matter smart home standard, an open-source IoT compatibility standard that aims to unite the smart home’s disparate devices and ecosystems and make everything work together, it can be difficult to chart your course. Compatibility choices come with different costs as each standard your device supports costs development dollars and often leads to having to support more SKUs in the market.

Fortunately, Cardinal Peak has been navigating the smart home product design waters for years and can help you chart the best course. We have worked on smart home products in all of the subcategories listed above. Check out some of our smart device engineering case studies below and connect with us to discuss your next smart home project.

Smart Home Product Design Considerations

The market for smart home products continues to be fragmented. Tech giants like Amazon, Google, Samsung and Apple have all helped improve the end-user experience by making the myriad of single-purpose apps obsolete, but in doing so, they have isolated manufacturers from their customers as the consumer no longer interacts with a manufacturer-branded app. This level of fragmentation makes it increasingly difficult for companies focused on smart product design to develop and maintain brand loyalty and differentiate on anything other than price.

Additionally, IoT platform-as-a-service companies like Tuya, Ayla Networks, Thingworx and others have further commoditized the smart home engineering market by making connected devices using their platforms all fit within narrow use cases. In trying to lower the IoT product development and smart home app development cost, these platforms have made product differentiation increasingly difficult.

Not to worry, these are the same smart device engineering challenges that Cardinal Peak has faced with other customers — and we can help you successfully navigate these concerns as well. Considering every smart home product design is different, we are here to discuss your unique value proposition and develop differentiated devices that delight your customers.

Our end-to-end design capability — including hardware, embedded software, the cloud and user apps — is all under one roof, so we can quickly and efficiently help you reduce both cost and time to market for your value-added product.

Smart Product Design FAQs

What is a Smart Home Device?

Smart home is a category of Internet of Things (IoT) products that are specifically designed for use in the home. Common examples of smart home devices include thermostats, Wi-Fi or BLE door locks, lighting controls, outlets, etc. In addition to the connected devices, smart homes often include hubs or gateways that allow products using a variety of protocols, such as Zigbee, BLE, 6LoWPAN and others, to connect. Increasingly popular in smart home control are smart speakers, such as the Amazon Echo or Google Home products, which allow homeowners to control smart devices using voice systems engineering. Primary use cases for smart homes include 1) home automation, 2) home security and 3) monitoring while away.

How Long Does it Take to Design a Smart Device?

For a ground-up design of a new smart home product (not a white-labeled product), a reasonable expectation for smart device design and testing is six to nine months. This includes the industrial design for the package, including molds. It also assumes the development of a new printed circuit board and the embedded software necessary to run the device, communicate with the cloud and perform over-the-air software updates. Much of the electrical design happens in parallel to the mechanical design as does smart home app development and the design of any cloud services supporting the device. Included in the schedule is time for alpha and beta testing of the end-to-end product. For products that are leveraging an existing product design, timeframes can be greatly compressed.

What are the Steps in Smart Device Design?

The first step in all smart home product design is envisioning the value proposition of the product (ideation) and documenting the features that need to be implemented (the requirements). For smart home products, this step needs to consider compatibility with other smart home products, such as Alexa or one of the other voice assistants. Leveraging existing infrastructure can greatly reduce your development cost and speed the schedule at the expense of limiting your market. For example, developing a device that is exclusively controlled through Alexa eliminates the need to develop an app, but only customers that use Alexa can use your product.

When it comes to smart home engineering, the first step is to describe the data that needs to be collected, processed and displayed by the device so that the device-to-cloud and the cloud-to-app interfaces can be described. Given a good interface description, the development of the device, cloud application and end-user app can proceed in parallel as engineers work to the API (application programming interface), which has likely been mocked up with a test harness. As features are implemented end to end, the smart home device undergoes regular QA testing for each new feature, as well as regression testing for previously developed features. When the smart device design and development is complete, testing expands to alpha testing (“friends and family”) then beta testing (small set of customers), during which any manufacturing test and configuration tools are prepared. Finally, the product is released. As widespread user data comes back and the marketing team sees the features that resonate with customers, functionality is added or tweaked and pushed out through OTA updates.
