FAQ

Does the Dongle Plus MG24 work with the eWeLink app?

No, the Dongle Plus MG24 is designed exclusively for local operation via open-source platforms like Home Assistant, Zigbee2MQTT, and openHAB. It does not integrate with SONOFF's eWeLink cloud ecosystem.

Can the Dongle Plus MG24 be used as a Thread router for Matter?

Yes, by flashing the OpenThread RCP or MultiPAN RCP firmware via the SONOFF Dongle Flasher, the Dongle Plus MG24 can act as a Thread coordinator and contribute to a Matter-over-Thread network depending on your platform configuration.

Is the USB extension cable essential?

It is not mandatory, but strongly recommended. By moving the dongle away from the host's USB port, it reduces electromagnetic interference generated by surrounding computer hardware, which improves the Zigbee signal range and stability.
