2026 verdict
Zigbee flexibility is the deciding factor in this Sonoff dongle pair, and on that count the Sonoff Dongle Plus MG24 wins.
It is the cheaper, better-reviewed radio, working as a Zigbee 3.0 coordinator and router that also flashes into a Thread border router for Matter, with a stronger antenna gain than the PZG23. The Sonoff Dongle-PZG23 is not a competitor on Zigbee at all, it is a dedicated Z-Wave 800 controller with S2 security and Z-Wave Long Range, so it is the one to reach for when locks, sensors and thermostats run on Z-Wave. Both sticks are plug-and-play with Home Assistant, USB-only, and ship with a USB extension cable. Pick the Sonoff Dongle Plus MG24 for cheap, flexible Zigbee and optional Thread; pick the Sonoff Dongle-PZG23 when Z-Wave is what you actually need.

What the differences mean
Protocol
The Sonoff Dongle Plus MG24 is a Zigbee 3.0 coordinator that can be flashed into a Thread radio. The Sonoff Dongle-PZG23 is a dedicated Z-Wave 800 controller. Neither substitutes for the other.
Antenna design
The Sonoff Dongle-PZG23's external antenna is adjustable. The Sonoff Dongle Plus MG24's antenna is permanently fixed, so repositioning the whole stick with the bundled USB extension is the only way to change its placement.
Antenna gain
The Sonoff Dongle Plus MG24 is rated at +4.5dBi against the Sonoff Dongle-PZG23's 2dBi.
Thread and Matter path
The Sonoff Dongle Plus MG24 can be flashed into a Thread border router for Matter. The Sonoff Dongle-PZG23 has no Thread or Matter path at all, being Z-Wave only.
Which one to buy if
- your devices are Zigbee, or you want the option of a Thread border router too
The Sonoff Dongle Plus MG24 coordinates Zigbee and flashes into Thread; the PZG23 does neither.

What owners say
Owners of both Sonoff dongles describe the same plug-and-play experience with Home Assistant, recognized in minutes with no flashing needed for either protocol out of the box. Sonoff Dongle Plus MG24 owners like the more compact, cooler-running design over the older ZBDongle-P and use the bundled USB extension cable to move the antenna clear of interference, while their one real gripe is that the antenna is permanently fixed, so unlike some Wi-Fi dongles it cannot be swapped for a bigger one. Sonoff Dongle-PZG23 owners report rock-solid stability with no dropped devices across a wide mix of hardware, from a Schlage deadbolt to decade-old Z-Wave gear migrated from a retired hub, and credit the adjustable external antenna and Z-Wave Long Range for reach beyond cheaper dongles, though a couple note they have only owned it a short time and cannot yet speak to long-term durability.
