The right choice starts with specifications
SKU: SLZB-06Mg26
Specifications checked against the linked manufacturer documents.Checked 18 October 2026
Connectivity — what it meansThe wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway. | Zigbee, ThreadOne radio runs either Zigbee 3.0 or Thread; the protocol is chosen by firmware in the web interface [1] |
|---|---|
Number of radios — what it meansHow many independent radio chips are inside. With two, Zigbee and Thread run at the same time, each on its own channel; with one, the protocol is chosen by firmware. | 1One Zigbee/Thread radio chip. The maker calls the series 'triple radio' because a separate ESP32 adds Wi-Fi and Bluetooth; Zigbee and Thread on separate chips at the same time are only on the SLZB-MR series [2] |
Radio chips — what it meansThe radio chip model (both chips on dual-radio models). It determines the available firmware, support in Zigbee2MQTT and ZHA, Thread capability and memory headroom for large networks. Texas Instruments (CC) and Silicon Labs (EFR32) chips use different firmware and update methods. | Silicon Labs EFR32MG26 [1] |
Connection to the server — what it meansHow the coordinator talks to Home Assistant or another server. With Ethernet and PoE it can sit in the middle of the house, far from the server; Wi-Fi needs no cable but depends on wireless quality; USB plugs straight into the server. | Ethernet, PoE (power and data on one cable), Wi-Fi, USBZigbee-to-Ethernet, Zigbee-to-Wi-Fi (2.4 GHz) and Zigbee-to-USB (USB-C) modes are switched in the web interface or with the button. USB and Ethernet/PoE can be connected at the same time thanks to optoelectronic isolation [3] |
Compatible software — what it meansWhich smart-home software the coordinator works with according to the maker's documentation: ZHA and Zigbee2MQTT for Zigbee, OpenThread Border Router for Thread, Z-Wave JS for Z-Wave. The coordinator only works together with such software on a server or mini PC. | Home Assistant ZHA, Zigbee2MQTT, OpenThread Border RouterZHA and Zigbee2MQTT for Zigbee; OpenThread Border Router (Home Assistant add-on) for Thread, with the coordinator acting as the Thread radio [1] |
Transmit power — what it meansThe coordinator's maximum radio output. Higher power gives a steadier link to distant devices, but range in a home depends more on walls and the number of routers in the network. | 20 dBmThe model page says '+20 dBm TX power'; the spec table says 'Zigbee SoC output gain +20dB' [1] |
Antenna — what it meansAn external detachable antenna can be turned or replaced with another; an internal one sits inside the housing. The antenna gain (dBi) is in the note. | External, detachableThe external 5 dBi antenna (maker: '+5dB') comes separately in the box and rotates in three axes; Wi-Fi/Bluetooth use an internal 2 dBi antenna [5] |
Home Assistant — what it meansHow the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration. | Native integrationHome Assistant discovers the coordinator on the network and adds it through the built-in ZHA integration; Zigbee2MQTT is installed separately. An SMLIGHT integration manages the device itself [3] |
Max connected devices — what it meansHow many devices can run on this coordinator's network according to the manufacturer. If the figure is for direct connections and the network grows through routers, this is noted. | Not stated by the manufacturer |
Wireless range — what it meansThe stated radio range, usually in open space. Walls and floors cut it noticeably. | Not stated by the manufacturer |
| Control processor | Espressif ESP32 (Wi-Fi, Bluetooth, SLZB-OS)The SLZB-06Mg26U revision uses an ESP32-S3 with extra PSRAM [1] |
| Ethernet controller | Microchip LAN8720The SLZB-06Mg26U revision uses a WIZnet W5500 [1] |
| USB-UART bridge | Silicon Labs CP2102 [1] |
| Ports and slots | 1 × USB Type-C (power and data) [1] |
Ethernet speed — what it meansMaximum speed of the wired network port. 100 Mbps is enough for smart-home control; 1000 Mbps makes a difference for backups and video. | 100 Mbps'10/100 Mb' per the current SLZB-06Mg26U page [6] |
| Bluetooth | BLE via the ESP32 with ESPHome firmware (Bluetooth proxy for Home Assistant) [7] |
Operating modes (firmware) — what it meansWhich role the radio can take with the maker's official firmware: a Zigbee coordinator creates and runs the network, a Zigbee router only extends an existing one, a Thread radio (RCP) works with an OpenThread border router, and MultiPAN runs Zigbee and Thread on one chip at once. | Zigbee coordinator, Zigbee router (repeater), Thread radio (OpenThread RCP)The role is set by firmware in the web interface. A built-in Thread border router (OTBR on the device) is only on the SLZB-06Mg26U revision [4] |
|---|---|
Management and updates — what it meansWhat is available for managing the coordinator itself: a web interface in the browser, firmware updates over the network without removing the device, VPN for remote access. | Web interface, firmware updates over the network, VPN (e.g. WireGuard)SLZB-OS web interface with login; radio chip and ESP32 firmware updates over the network; WireGuard VPN [5] |
| Standalone Zigbee hub mode | NoThe mode is only available on Texas Instruments models (SLZB-06, 06p7, 06p10) [8] |
| Mode switching | Ethernet / Wi-Fi / USB — in the web interface or with the button, no mechanical switches [1] |
Power source — what it meansWhere the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery. | PoE (over Ethernet), USBPoE IEEE 802.3af or USB Type-C 5 V; both can be connected at once, no switch needed [1] |
|---|---|
Rated power — what it meansThe rated or maximum power draw from the spec sheet. It sets the load on the socket and the energy use. | 1.5 WThe model page says 'Low power consumption up to 1.5W'; its 'if both radio SoCs are running' wording is carried over from the MR series. The current SLZB-06Mg26U page says 1–1.5 W [1] |
Mounting — what it meansHow and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket. | Adhesive tape, screw-fixed (surface)Double-sided tape and screws with a screwdriver are included. DIN-rail mounting is mentioned on the model page only via 3D-printable models [5] |
|---|---|
Dimensions — what it meansThe device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf. | 160 × 22 × 24 mmWithout antenna, per the SLZB-06Mg26 page. The current SLZB-06Mg26U page (same housing) states 160 × 24 × 28 mm; the antenna is 192 × 12 × 12 mm [1] |
Weight — what it meansThe device’s weight without packaging, per the maker. | 86 gWithout antenna (antenna 15 g). Stated on the current SLZB-06Mg26U page; the non-U SLZB-06Mg26 page does not give it [6] |
Operating temperature — what it meansThe air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms. | 5–35 °C'Operating environment: +5 – +35 C'; the SLZB-06Mg26U page gives the same [1] |

A fast broadband plan does not fix weak signal through a wall. Several apps do not become one system by themselves. Placement and verified connections matter.
