The right choice starts with specifications
SKU: SONOFF-ZBDONGLE-P
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. | ZigbeeZigbee 3.0 (IEEE 802.15.4, 2.4 GHz). SONOFF's list has no official Thread firmware for ZBDongle-P [1] |
|---|---|
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, ioBroker, DomoticzHomeSeer and Jeedom are also listed. The maker marks openHAB as not supported [3] |
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 dBmUp to +20 dBm; per SONOFF's comparison chart the factory firmware defaults to 5 dBm. The EU declaration gives Zigbee output ≤ 13 dBm [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, detachableRotatable antenna on an SMA connector, 2 dBi gain [1] |
Wireless range — what it meansThe stated radio range, usually in open space. Walls and floors cut it noticeably. | 135 mIn free line of sight [2] |
Network devices (per maker) — what it meansHow many devices the maker says a network with this coordinator can handle. The real limit depends on firmware and the number of routers in the network; direct connections to the stick itself are usually fewer. | 200With routers in the network; up to 50 devices directly on the stick (maker's FAQ) [1] |
| Radio frequencies and transmit power | Zigbee 2405–2480 MHz, EU ≤ 13 dBm [7] |
| Supported operating systems | Windows, Ubuntu, Raspberry Pi OS, Docker [2] |
Radio chip — what it meansThe chip that handles the radio link. It determines which firmware is available, support in Zigbee2MQTT, ZHA and Z-Wave JS, and the memory headroom for large networks. Silicon Labs (EFR32) and Texas Instruments (CC) chips use different firmware and drivers. | Texas Instruments CC2652P [2] |
|---|---|
Radio chip memory (Flash / RAM) — what it meansThe chip's flash and RAM size. More memory leaves room for the routing tables of large networks and for future firmware, including Thread and Matter. | Not stated by the manufacturer |
USB-to-serial chip — what it meansThe chip through which the radio talks to the computer over USB. CP210x and CH9102 drivers are already in Linux and Home Assistant OS; on Windows they sometimes need installing manually. On some sticks USB is built into the radio chip itself. | Silicon Labs CP2102 / CP2102NCP2102(N) [2] |
Colour — what it meansThe housing colour of this model. Other colours in the same series are separate products. | Black [6] |
| USB product description | SONOFF Zigbee 3.0 USB Dongle Plus [8] |
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)Custom firmware is officially supported too. Thread RCP and MultiPAN are not on the supported-firmware list for ZBDongle-P [4] |
|---|---|
Factory firmware — what it meansThe firmware the stick ships with: the stack and, where stated, its version (e.g. EmberZNet or Z-Stack). It decides which driver to pick in Zigbee2MQTT or ZHA on first connection. | Zigbee coordinator on Z-Stack 3.x.0 (ZNP protocol) [1] |
Firmware update method — what it meansHow firmware is changed or updated. Over USB it takes a few minutes from a browser or a Home Assistant add-on; older sticks need a separate hardware programmer. | Over USB, no programmerVia the official SONOFF Dongle Flasher web tool in a browser or the Home Assistant add-on [1] |
| Host serial protocol | Z-Stack (ZNP) [8] |
| UART flow control | None by default; hardware flow control is enabled with the on-board DIP switch when running firmware that supports it [8] |
USB connector — what it meansWhether the stick plugs straight into a USB-A port or connects by cable to a USB-C socket on its housing. The radio is best kept away from USB 3.0 ports and the computer case; an extension cable is used for that. | USB-A plugUSB-A plug on the housing itself (per the maker's photos and drawing) [1] |
|---|---|
Housing material — what it meansThe plastic or metal the housing and cover are made of. Polycarbonate (PC) usually withstands impact and heat better than ABS; a clear cover lets you see the module’s indicators without opening the box. | AluminiumAluminium alloy [1] |
Dimensions — what it meansThe device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf. | 87 × 25.5 × 13.5 mmWithout the antenna; with the antenna fitted the maker's drawing shows 108 mm overall length [2] |
Weight — what it meansThe device’s weight without packaging, per the maker. | 28 gWithout the antenna [6] |
Certifications — what it meansStandards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter). | CE, FCC, RoHS [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. | −10…40 °C [1] |
|---|---|
Operating humidity — what it meansThe rated relative humidity range, non-condensing. | 5–95%Non-condensing [2] |
Package contents — what it meansWhat comes in the box, per the maker. | ZBDongle-P stick, antenna, quick guideNo USB extension cable included; the maker offers one separately (1.5 m) [5] |
|---|---|
Manufacturer warranty — what it meansThe warranty period the maker states. Confirm warranty terms in Moldova with the seller. | 24 months“2-Year Hassle-Free Warranty” on the official SONOFF store page; warranty terms of a regional seller may differ [1] |
Supply voltage — what it meansThe supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter. | 5 V ⎓ 100 mA max (from the USB port) [1] |
|---|---|
Standby power — what it meansHow much power the device draws on its own while idle. It matters for devices that run around the clock. | 0.04 W40 mW [2] |

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.
