The Ultimate Enterprise Level Hub
SMHUB is a professional-grade control hub running a Linux-based system that can host apps locally — Zigbee2MQTT, MQTT broker, Z-Wave JS, WireGuard, Tailscale, Matterbridge, and more. Despite working seamlessly with smart home systems like Home Assistant, OpenHAB, HomeSeer, or others, with Zigbee2MQTT and Matterbridge it can also expose Zigbee devices directly to Google Home or Apple Home without any additional hubs ( Zigbee device → SMHUB → Google/Apple Home).
At SMLIGHT, we delivered multiple complete solutions for smart home networks - and the SLZB-06 series and SLZB-MR series of Zigbee+Thread+Wi-Fi+ Bluetooth coordinators became well known and beloved by thousands of customers. Many users told us they wanted to decouple Zigbee software like Zigbee2MQTT from their home servers for better stability. That insight led us to build a hub that can run the software itself: a fully fledged Linux system designed for reliability and simplicity.
Adapters solved connectivity. SLZB-06 and SLZB-MR series reliably connected devices to any smart home platform.
SMHUB solves integration. It runs Linux packages directly on the hub - Zigbee2MQTT, Matterbridge, Node-RED, WireGuard, Mosquitto MQTT - so you don’t have to juggle separate servers, bridges, and dongles.
Smart homes often become fragmented: software on one server, radios on another device, separate bridges for each ecosystem. SMHUB changes that. By bringing radios, Linux-run software, and high-value peripherals together, it delivers a stable, feature-rich, and future-proof experience — without making regular users pay for features they don’t use.
SMHUB adapts to your smart system setup. Whether you want (a) a complete standalone hub, (b) a Matter bridge to Google/Apple ecosystems, or (c) a powerful remote radio coordinator for platforms like Home Assistant, OpenHub, HomeSeer and so on – SMHUB gives you the flexibility to choose.
Use SMHUB as a standalone control hub: Run Zigbee2MQTT, MQTT-broker, Node-Red and pair Zigbee, Thread (or even Z-Wave devices via add-on) directly and manage them through the hub’s built-in apps. No need for external platforms like Home Assistant or OpenHAB – everything runs locally, securely, and reliably.
Leverage SMHUB’s Zigbee2MQTT and Matterbridge app to connect Zigbee devices from any manufacturer (via Zigbee2MQTT) and make them visible in Google Home, Apple Home, or other Matter-compatible systems. Seamlessly integrate your devices into any modern ecosystems.
Use SMHUB as a dedicated Zigbee/Thread/Z-Wave coordinator connected to your favorite smart control system such as Home Assistant, OpenHAB, HomeSeer or any other. Let your existing smart system software control all end devices via SMHUB’s reliable multi-radio hardware. Utilize Ethernet, USB or Wi-Fi connection
Texas Instruments + Silicon Labs for robust, low-latency links.
Expansion modules (e.g., Z-Wave or 4G) can be added via USB, UART, or SPI, keeping SMHUB compact and low-power while delivering enterprise-level stability and DIY flexibility.

SMHUB exists in two hardware variants to give you flexibility in choosing the right radios for your setup. All functionality is identical across both editions – the only difference is the radio SoCs used.
🔹 SMHUB Essential – CC2652P + EFR32MG21
🔹 SMHUB Premium – CC2674P10 + EFR32MG24
Both variants run SMHUB-OS with the same features: Zigbee2MQTT, Matterbridge, Node-RED, modular expansion, and enterprise-ready performance. Your choice simply depends on which radio chipsets you prefer for your setup or future-proofing.
IMPORTANT NOTE: EARLY ADOPTER VERSION
The SMHUB Early Adopter Version is the first public release of our new multi-radio smart hub. This is reflected in a discounted price for early buyers.
A quick, side-by-side look at pain points versus what you get with SMHUB.
SMHUB is a complete, standalone smart home hub that delivers full functionality out of the box. At the same time, its architecture allows selected expansion modules to further enhance connectivity and resilience when specific use cases demand it. The add-ons listed below are ready-to-use, but SMHUB can also support any third-party or custom modules that communicate over UART, SPI, I²C, or USB protocols. Ready to use modules are:
Adds full Z-Wave 700/800-series controller functionality (same chip as used in SLZB-MRW10, ZWA-2 and similar Z-Wave adapters), supporting Z-Wave Long Range, S2 security, and SmartStart provisioning. Enables smooth integration of Z-Wave networks alongside Zigbee, Thread, or Matter in a unified hub.
Based on the powerful 4G modem, providing LTE Cat-1 connectivity with GSM/EDGE fallback. Supports SIM slot, external antennas, and secure data channels for backup internet or remote access where wired broadband isn’t available.
Enables Power-over-Ethernet functionality, simplifying installations with a single cable for both data and power. Ideal for setups where reliable wired networking and centralized power management are required.
Works with standard 2x 18650 batteries, features control buttons, and supports charging from a SOLAR PANEL in addition to conventional power sources. Built on an advanced battery management system, it provides backup power, charge/discharge protection, monitoring, and SMHUB-OS-controlled shutdown to keep SMHUB online during outages.
The UPS module provides backup power for SMHUB, ensuring uninterrupted operation during outages or unstable supply. It is designed around 2x standard 18650 batteries, supports multiple charging options, and can also be powered by a SOLAR PANEL. This is an early prototype currently under development (yes, we already have tested and even developed enclosure), however market launch can take yet some time, so this is announcement of development, rather than a clear commitment with specific date.
| 2x Standard 18650 batteries | Hot-swappable 18650 cells, widely available and easy to replace. |
| Multiple power inputs | Can be charged via USB-C, dedicated DC-IN, SMHUB's POE or SOLAR PANEL - making it really power efficient and independent. |
| Solar-ready design | Optimized charging path allows direct solar panel connection for off-grid or outdoor use. |
| Stable power delivery | Integrated DC-DC converters provide regulated 5V rail for the hub. |
| Comprehensive protection | Safeguards against over-discharge, over-charge and short-circuit. |
| Multi-level LED indicators | Four LEDs display battery charge levels; RGB LED shows charging, discharging, or fault status. |
| Audible alerts | Integrated buzzer warns of low battery or fault states for immediate awareness. |
| User controls | Two physical buttons allow safe power management, reset, and interaction without disconnecting the hub. |
| SPI interface | Enables host devices (for example, SMHUB) to read UPS status or control its operation directly over SPI communication. |
| Broad compatibility | While designed initially for SMHUB only, the UPS add-on can power any 5V device, extending its use to other electronics and DIY projects. |
✅ SMHUB bridges the gap between dedicated coordinators, DIY setups, and closed consumer hubs. It delivers enterprise reliability, modular expandability, and openness in one device.
