@cyrilpawelko and others have posted that OpenHAB works with Tasmota’s Serial-to-IP bridge on Sonoff ZBBridge Zigbee Bridge with EmberZNet 6.7 firmware so that should mean that ITead’s upcoming USB dongle will probably work-out-of-box with “Ember EM35x Coordinator” in OpenHAB Zigbee Bindings.
That is as, long have drivers for Silabs CP210x (USB to UART Bridge VCP Virtual COM Port) is already installed in the operating system, (and note reboot is required on Windows OS after install VCP driver).
Note! Ember USB Zigbee adapters/dongles/sticks are highly recommended over using a remotly connected Ember module using a serial-to-ip bridge / serial forwarding server like ser2net. The reazon for this is that clients using the EZSP serial protocol requires a robust connection between the EmberZNet Zigbee stack running on EFR32 MCU and the serial port of the Zigbee radio. With solutions such as ITEAD Sonoff ZBBridge or a Ser2Net serial proxy connection over a WiFi network it is expected to see NCP entered failed state. Requesting APP controller restart in the logs. This is a normal part of the operation and indicates there was a drop in communication which caused packet loss to occurred between the zigpy radio library and the Zigbee radio. The use of serial network proxies/bridges/servers over WiFi is therefore not recommended when wanting a stable Zigbee environment with Silicon Labs Ember based Zigbee radios. The developers of the bellows radio library for the zigpy project has more information about this if needed.
