Silicon Labs has introduced a series of comprehensive reference designs that reduce time-to-market and simplify the development of ZigBee-based home automation, connected lighting and smart gateway products.
The reference designs include the hardware, firmware and software tools that developers need to create interoperable, scalable, feature-rich connected home products based on Silicon Labs’ robust, industry-leading ZigBee “Golden Unit” Home Automation (HA 1.2) software stack and ZigBee SoC mesh networking technology.
“The connected home is one of the most attractive markets for wireless connectivity, driven by a number of compelling applications such as home automation and connected lighting, and it’s growing quickly too,” said Lee Ratliff, principal analyst, connectivity and IoT, IHS Technology. IHS forecasts that connected home device shipments will grow from 59m units in 2015 to 193m units in 2018, a compounded annual growth rate of more than 48%. According to Ratliff, successful connected home products must be standards-based, easy to deploy by mainstream consumers, and designed to work in real-world environments and solve specific problems with minimal complexity.
Silicon Labs created cost-effective reference designs to significantly reduce the complexity of connecting ZigBee devices, such as lights, dimmer switches and door/window contact sensors, in a connected home network. This design simplicity translates into exceptional ease of use for consumers who are increasingly purchasing 'do-it-yourself' connected home products at leading home improvement retailers such as Home Depot and Lowes.
Silicon Labs’ ZigBee connected lighting reference designs feature wireless lighting boards as well as a plug-in demo board suitable for quick demonstrations and testing. The Golden-unit ZigBee stack allows LED lights to reliably join, interoperate and leave a mesh network, as well as scale from a few to hundreds of light nodes on the same network. The connected lights can support white, colour temperature tuning and RGB colour settings as well as dimming.
Silicon Labs’ ZigBee-based home automation reference designs include a capacitive-sense dimmable light switch and a small-form-factor door/window contact sensor. The light switch provides colour, colour tuning and dimming control capabilities that traditional switches cannot achieve. Unlike conventional switches, these wireless, battery-powered switches have no moving parts and are easy to place anywhere in a home. The switch design features Silicon Labs’ EFM8 capacitive sensing MCU to detect different user gestures (touch, hold and swipe). The contact sensor reference design provides all the tools needed to create wireless, battery-powered sensors used to monitor door and window positions (open or closed) – a useful feature for automatically triggering room lighting.
Silicon Labs offers two ZigBee gateway options to complement the reference designs:
Both gateway options allow developers to control and monitor ZigBee HA 1.2 compliant end nodes through WiFi with any device with a web browser, such as a smartphone or tablet. Using an intuitive, web-based user interface, developers can easily create rules between ZigBee end devices including lights, dimmable light switches and contact sensors.
The connected lighting and home automation reference designs support the following features:
Greg Hodgson, Senior Director, IoT Solutions, Silicon Labs, commented: “Developers creating connected home products want simple, high-performance, battery-friendly solutions that make wireless design fast, easy and straightforward. Our new connected lighting, home automation and ZigBee gateway reference designs meet these developer priorities, providing the most robust, easiest to use hardware/software solutions available.”
As the ZigBee market share leader with 10+ years of experience in mesh networking, Silicon Labs has become a trusted partner for customers in the connected home market. Silicon Labs is a founding member of the Thread Group and the first to demonstrate a Thread network and deliver a Thread stack. While mesh networking solutions from other chip vendors often fall short in real-world applications, Silicon Labs’ robust, field-proven software stacks enable connected devices to join mesh networks quickly and consistently and route messages reliably.
