Product description: SMLIGHT SLZB-MR1 - ZigBee / Thread Multiradio gateway CC2652P7 EFR32MG21 for Home Assistant - Ethernet / PoE / USB / LAN / WiFi
The SLZB-MR1 is a SMLIGHT multi-radio coordinator designed for modern Smart Home systems that prioritize stability, flexibility, and simultaneous support for multiple protocols. The gateway utilizes two separate radio chips – the CC2652P7 and the EFR32MG21 – allowing it to support ZigBee and Thread networks simultaneously , without the limitations of multiprotocol firmware. The adapter operates via Ethernet, PoE, WiFi, or USB Type-C , and the SLZB-OS system provides configuration via a web interface, OTA updates, VPN support, scripting, and networking features. This solution is for Home Assistant users who want to build an efficient, future-proof, and easily expandable home automation installation.
SMLIGHT SLZB-MR1 - ZigBee / Thread Multiradio CC2652P7 EFR32MG21 gateway for Home Assistant - Ethernet / PoE / USB / LAN / WiFi.
The SLZB-MR1 combines the CC2652P7 (Texas Instruments) and EFR32MG21 (Silicon Labs) chips in one device.
Main features of the ZigBee and Thread coordinator
- Two radio chips : Texas Instruments CC2652P7 and Silicon Labs EFR32MG21 enable independent ZigBee and Thread support
- Multiradio : simultaneous operation of ZigBee 3.0 and Thread/Matter-over-Thread on separate chips
- Home Assistant compatibility : works with Zigbee2MQTT, ZHA and OpenThread Border Router
- Ethernet, PoE, WiFi and USB Type-C connectivity : versatile installation for your home, office or IoT project
- PoE or USB Type-C Power : Can be powered via Ethernet or 5V DC power
- Two external SMA antennas : separate 2.4 GHz antenna for each radio chip
- High transmitting power : up to 20 dBm for both radio systems
- SLZB-OS : Web interface, OTA updates, VPN, scripting, network settings and security
- Low power consumption : up to 1.5 W when both radio systems are operating
- Installation in various places : ABS housing with ventilation, can be mounted on a wall, DIN rail or with tape
- LED indicators : 6 independent LEDs informing about the status of the device and radio systems
- Multi-function button : support for mode change, reset and other functions
ZigBee and Thread - two standards in one Multiradio coordinator
ZigBee is a proven and energy-efficient wireless communication standard widely used in sensors, relays, lighting, sockets, thermostats, and smart home controllers. Thread is a modern IPv6-based network protocol used in Matter-over-Thread solutions, among others. The SLZB-MR1 adapter allows you to use both technologies simultaneously , as it has two independent radio systems instead of a single shared module. This allows you to build a stable ZigBee network and simultaneously expand your Thread/Matter infrastructure without abandoning your existing Smart Home devices.
The set includes two external SMA antennas.
The adapter offers Ethernet (LAN) connectivity, USB Type-C for data and power transfer, WiFi, and support for Power over Ethernet (PoE).
