Our first product says it all
The Sentinel Core, redefines what’s possible in home automation. A custom Raspberry Pi 5 with a PCIe port, it lets you connect a GPU to run powerful large language models (LLMs) locally—the backbone of privacy-respecting, offline voice assistants. This isn’t just about smarter homes; it’s about reclaiming autonomy and pushing boundaries.
And we’re just getting started.
While our current focus is on Home Assistant LLMs, the possibilities extend far beyond voice control. Every product we create is crafted to empower innovators like you, ensuring every detail delivers seamless, polished performance.
Sanctuary Systems isn’t just about technology; it’s about helping you take pride in your creations. Innovate boldly, reclaim your potential, and transform your home into the sanctuary it’s meant to be.
Your system, your sanctuary
Unleash Local AI Potential
The Sentinel Core is your toolkit for crafting a powerful, private, and fully autonomous home. Designed with creators in mind, it gives you the freedom to innovate, reclaim control, and safeguard your sanctuary.
Built for Experimenters
We believe in giving creators total control. Sentinel Core ships as a powerful hardware platform, you decide how to build on it. GPU-accelerated local AI on Raspberry Pi is still a frontier, and while it’s possible, it requires experimentation and a willingness to tinker. We have a quick-start guide to help you take the first steps, and we plan to share more community-driven resources over time as the ecosystem evolves.
Customizable and Future-Ready
Its Mini ITX form factor offers compatibility with repurposed PC components, giving you the freedom to customize and upgrade as needed, while maintaining a premium, compact build.
Energy Efficiency Meets Performance
Built on the Raspberry Pi 5 foundation, the Sentinel Core delivers exceptional energy efficiency without sacrificing capability.
Your Sanctuary, Your Setup
This custom Raspberry Pi 5 features a PCIe port for the GPU of your choice, unlocking new possibilities for local AI and LLM experimentation. It’s a platform built for those who want to explore, innovate, and push the boundaries of what’s possible, privately and on their own terms.
