Hello @mnbf9rca as you have the emonTx4 connected via USB and have the radio turned off you do not need to configure emonHub nodes. The serial data comes through already decoded and bypasses that part of emonHub.
It looks like the inputs are appearing as expected. The energy values are not printed over the serial connection, it only prints the 12 power values, voltage and frequency. This was configured this way to support use of the emonTx4 with the EmonESP WiFi module which struggled with very long serial messages.
MSG:1,V1:239.13,F:50.44,P1:1,P2:15,P3:91,P4:97,P5:1,P6:124,P7:155,P8:156,P9:141,P10:0,P11:0,P12:9
One option if you want to use the energy registers, is to enable the radio and receive the data that way, it will transmit two data packets as @Robert.Wall describes and include the energy registers.
