Description
Looking for a compact Zigbee USB dongle in Jordan to run your smart home locally on Home Assistant or Zigbee2MQTT? The SONOFF Dongle Lite MG21 costs 25 JOD at Bestways, the exclusive SONOFF distributor in Jordan, with one unified price at every authorised dealer and a 12-month warranty from the official distributor. Requires a host computer running an open-source platform such as Home Assistant.
The SONOFF Dongle Lite MG21 (Dongle-LMG21) is a compact Zigbee/Thread USB dongle built on the proven EFR32MG21 chip, trusted by millions of users for reliable, stable performance. It works as a Zigbee coordinator for Home Assistant, Zigbee2MQTT, openHAB and other open-source platforms, for local control of your Zigbee devices.
It is 65% smaller than the ZBDongle-E, so it fits more easily into different USB ports. The SONOFF Dongle Flasher tool lets you switch firmware to run it as a Zigbee router, OpenThread RCP or MultiPAN RCP, and the included USB extension cable lets you place it away from USB 3.0 interference.
Note: the dongle needs a host computer running an open-source platform such as Home Assistant, Zigbee2MQTT or openHAB.
