Add inching for zbmini l2

Hello, there. Would you please add inching option for zbmini l2. As now is missing I have to replace zbmini 2 with mini 4 extream + s-mate which is not convenient.

Thank you

Inching is not part of the official Zigbee protocol specifications. As eWeLink / Sonoff sticks to the official Zigbee protocol specifications you better don’t expect it to be ever get added,
