Problem:
When using OpenBeken on a LAN, other users can intercept a Zigbee stream via UARTTCP, since there is no security on the stream.
Proposed Solution:
Limit access based on the calling IP number. Add a parameter to UartTCP.
// startDriver UartTCP [baudrate] [buffer size] [connection channel] [hw flow control] [limit to IP]
e.g.
startdriver uarttcp 115200 512 1 1 172.16.1.220
Benefits:
Only Home Assistant or Zigbee2MQTT IP can access the stream if it is limited to a specific IP address.
