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. | Z-WaveZ-Wave 800 series with Z-Wave Long Range (ZWLR) and S2 security. The frequency region is set in software; for Europe 868.4/869.85 MHz (mesh) and 864.0/866.0 MHz (LR) [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. | Z-Wave JS, openHABHome Assistant via the Z-Wave integration with Z-Wave JS or Z-Wave JS UI; the stick is auto-discovered from version 2025.12.2. Zigbee software (ZHA, Zigbee2MQTT) does not work with this stick [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 dBmPlus a 2 dBi antenna. The EU declaration in the Quick Guide states Z-Wave ≤ 14 dBm [2] |
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, fixed (folding)Fixed folding antenna, rotates within 180°; 2 dBi gain [1] |
Wireless range — what it meansThe stated radio range, usually in open space. Walls and floors cut it noticeably. | 300 mMesh: 300 m; Z-Wave Long Range: 1000 m; open space, line of sight. Long Range works only with devices that support it [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. | Not stated by the manufacturer |
| Radio frequencies and transmit power | 860–930 MHz; EU: 868.4/869.85 MHz (mesh), 864.0/866.0 MHz (LR); US: 908.42/916 MHz (mesh), 912/920 MHz (LR); AU: 919.8/921.4 MHzThe region is chosen in Z-Wave JS / Z-Wave JS UI; the maker states it works in all regions [2] |
| Z-Wave Long Range | Yes [1] |
| Link security | Z-Wave S2 [1] |
| 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. | Silicon Labs EFR32ZG23 (Z-Wave 800) [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. | 512 KB Flash / 64 KB RAM32-bit ARM Cortex-M33 processor [1] |
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. | Grey'Dark Gray' per the maker [1] |
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. | Z-Wave controllerThe only firmware is a Z-Wave controller. The maker allows SONOFF firmware only; Zigbee and Thread are not available on this stick [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. | Z-Wave controller firmware (800 series); version not stated [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 programmerWith the SONOFF Dongle Flasher web tool; SONOFF firmware only [4] |
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 plugThe stick plugs straight into a USB-A port or via the included extension cable (official photos) [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. | Aluminium, PlasticAluminium alloy and PC+ABS [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. | 18 × 10.5 × 214 mmWith the antenna raised. Per the official dimension drawing the body is 62.5 mm long and the antenna 151.5 mm [2] |
Weight — what it meansThe device’s weight without packaging, per the maker. | 19.6 g [5] |
Certifications — what it meansStandards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter). | CE, FCC, RoHS [5] |
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…60 °C [2] |
|---|---|
Operating humidity — what it meansThe rated relative humidity range, non-condensing. | 5–95% [2] |
Package contents — what it meansWhat comes in the box, per the maker. | Z-Wave 800 Dongle Plus, 1 m USB extension cable, quick guideThe antenna is part of the housing, not a separate item [6] |
|---|---|
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] |
Power source — what it meansWhere the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery. | From the AC's USB socketFrom the host's USB port [2] |
|---|---|
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 ⎓ 500 mA [2] |
Standby power — what it meansHow much power the device draws on its own while idle. It matters for devices that run around the clock. | 0.06 W60 mW per the spec sheet [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.
