Industries / Building Automation

Each new device in your portfolio should cost less than the last. Not more.

Building automation teams deal with 15-year device lifecycles, multi-protocol portfolios, and a growing variant count. Most embedded platforms make that combination increasingly expensive over time. ROSA takes the opposite route: development tools and maintained modules your team uses, so each new device costs less than the last.

Let's talk

The challenge

Why firmware complexity compounds in Building Automation

Building automation sits at the intersection of long product lifecycles, a fast-moving protocol landscape, and growing pressure to ship more device types on tighter budgets. The firmware decisions made today will have consequences for 15 to 20 years. Most teams are not set up for that. The gap becomes visible faster than expected.

Quick Prototyping

A working device on your own hardware in days, not months.

Evaluating new firmware tooling usually means months of bring-up work before you can judge whether it fits. ROSA removes that barrier. Structured module templates, auto-generated interfaces, and built-in tooling mean your team has a working KNX-IoT or Matter device running on real hardware within days, and a capped pilot puts ROSA on your own SoC in one week. No commitment required.

What this means in practice

  • — First working module deployed in days, not weeks
  • — Auto-generated interfaces eliminate manual bring-up work
  • — Built-in observability lets you assess performance from the start
  • — Low-risk evaluation: if it does not fit your setup, you know fast

New Markets

KNX companies now have a path into Matter, KNX-IoT, and the consumer market.

Traditional KNX device manufacturers have deep domain expertise, strong installer relationships, and years of market trust. What they typically lack is the IP-based firmware to compete in a market moving toward Matter, KNX-IoT, and cloud connectivity: the protocol stacks, the security and update machinery, the test setup. Building all of that in-house takes years and a skill set most KNX teams do not have. With ROSA it arrives ready to use, as maintained modules that land in your repos as your own code. Established building automation players can enter new market segments without a multi-year platform investment, and without giving up what they already do well.

What this means in practice

  • — KNX-IoT and Matter support built in. No IP firmware expertise required to get to market.
  • — Consumer smart home segments become accessible to traditional KNX device makers
  • — First products in new market segments in months, not years
  • — Existing product logic carries over to IP-based devices without rewriting application code

Portfolio Scaling

Each new device costs less than the last.

In conventional embedded development the cost curve works against you. Every new device type carries roughly the same engineering weight as the first, and maintenance multiplies with every product in the field. ROSA inverts this. The shared machinery already exists as maintained modules, and 4Rooks keeps it current. Each new device is an incremental addition to what already exists. The larger your portfolio, the more the economics work in your favour.

What this means in practice

  • — Shared, maintained modules mean each new product is additive, not multiplicative
  • — Protocol and security updates handled once, across every device in your portfolio
  • — Keeping the OS base and shared modules current sits with 4Rooks, not your engineering team
  • — 15 to 20-year device lifecycles are manageable when 4Rooks maintains the shared modules and the OS base

Variants

Same application logic, any protocol, any hardware.

KNX-IoT, Matter, BLE, and BT Mesh are all active standards with their own update cadences and certification requirements. Managing each as a separate firmware base is how engineering capacity gets silently consumed. ROSA separates protocol and hardware handling from your application logic entirely. Your product code runs unchanged across your full device portfolio. Protocol updates happen once, in the maintained modules, not separately in every product.

What this means in practice

  • — Application logic shared across your full device portfolio, regardless of protocol or hardware
  • — Protocol stack updates (KNX-IoT, Matter, BLE, BT Mesh) absorbed in the maintained ROSA modules
  • — New hardware generation is a configuration change, not an architecture rewrite
  • — Adding a new device type does not fork your codebase
