Now it’s possible to buy Zigbee USB dongle what works directly (without flashing) with Zigbee2MQTT.
I hate to break the news for you, but that’s nothing new… Pre-flashed sticks are available at Amazon or Ali for quite a time now (I bought my first one over a year ago). It is new, that itead as manufacturer of the Sonoff devices now sells them, but that’s unfortunately all…
But flashing a CC2531 isn’t that difficult, it is done in five minutes withour prior knowledge.
I’ve just ordered on piece of that.
Do we know which Zigbee devices are compatible with this itead usb dongle?
Check zigbee2mqtt.io/devices. A big list.
