USB passthrough over TCP/IP — add Z-Wave, Matter, BLE dongle, etc.
-
Wi-Fi and Bluetooth (ESP32) for flexible placement and connectivity
-
Ethernet + PoE (Power over Ethernet) for stable network and power
-
USB-C for alternative power
-
Modular architecture — connect additional USB devices or a USB hub
-
Full compatibility: Zigbee2MQTT, Home Assistant, OpenThread, Z-Wave JS (via USB stick)
