B.One In-Wall Pico Relay: Small Device, Big Breakthrough in Smart Automation

As the smart home landscape rapidly evolves, the challenge isn’t just innovation — it’s integration. Retrofitting connected technology into tight electrical enclosures and older infrastructure remains one of the most overlooked pain points. Enter Blaze Automation’s B.One In-Wall Pico Relay — a product that proves compact design doesn’t have to come at the cost of performance. At just 17.6 mm thin, this ultra-slim module redefines how and where intelligent automation can be deployed.

Reimagining What Fits Inside a Wall

Most standard junction boxes are too shallow for conventional smart relays. Space constraints have always limited what’s possible behind existing switches, especially in legacy buildings. That’s exactly where the B.One Pico Relay delivers. With its incredibly compact form factor, it installs effortlessly behind switches and outlets - no messy surface-mounted boxes or complicated rewiring required. It’s a seamless way to upgrade traditional switchboards into smart, connected control panels without altering their appearance or layout.

But don’t let the size fool you. The Pico Relay is packed with capabilities that rival much larger devices. It supports Wi-Fi or Zigbee, handles loads up to 16A, and includes built-in protection against overheating, overload, and voltage fluctuations. All of this is wrapped into a form factor that makes it ideal for OEMs and system integrators looking for efficient, certifiable, and space-saving solutions.

Smart Functionality in the Tightest Spaces

From smart homes to commercial retrofits, the applications are as diverse as they are impactful. The Pico Relay is the go-to solution for installations where conventional relays simply won’t fit - such as shallow junction boxes, narrow switchboards, or multi-relay gang boxes. It allows users to transform ordinary switches into smart ones while maintaining their original look and feel.

Integrators can use it to power smart lighting scenes, automate fans or appliances, and enable energy monitoring — all while reducing the footprint of their automation stack. Its stealth design not only saves space but simplifies deployment across both new and retrofit projects. Multiple Pico Relays can even be installed side-by-side within a single gang box to support multi-channel control, making them ideal for compact, high-efficiency smart home builds.

Built by Blaze, Built for What’s Next

At the core of this innovation is Blaze Automation’s mission: building powerful automation hardware that’s as elegant as it is effective. The Pico Relay is a product of that philosophy — not just smaller, but smarter. It’s designed, engineered, and manufactured to meet strict quality and performance benchmarks that Blaze customers worldwide have come to trust.

For OEM partners, the Pico Relay offers a performance boost with minimal redesign. For integrators, it reduces complexity and expands installation possibilities. And for users, it offers a powerful, invisible layer of automation that enhances comfort, efficiency, and control.

Blaze Automation’s B.One In-Wall Pico Relay is a benchmark for where smart technology is heading - slimmer, smarter, and seamlessly embedded into the spaces we live and work in.
