iHost is a very good smart home hub, but it’s far from being an advanced hub, since even with the efforts of the eWeLink team, the Z2Cube is super limited compared to solutions like Zigbee2MQTT, ZHA and other hubs.
I would love the possibility of using custom third-party drivers in Zigbee2Cube, but since it doesn’t seem like a manufacturing vision, we could at least settle for the possibility of using Zigbee2MQTT by exporting devices directly to the Cube/iHost.
