To test a command just use the text over tcp entity and put this in the source parameter field for the switch to PC1 command: ip-address:5000, “raw=0xAA 0xBB 0x03 0x01 0x01 0xEE” . Replace ip-address with the real ip address of the device.
If this works I can help you with creating a custom entity config to get a remote entitiy with all commands and select entities for the switch commands and led timeout setting.
