3 phase monitoring with solar

I tried to startover with a blank installation, but sadly the “autoconf” was enabled, and it found the emontx3 via wireless and created the node…
As I attached the emontx3 via USB2Serial it created this:

    [[USB0]]
        Type = EmonHubOEMInterfacer
        [[[init_settings]]]
            com_port = /dev/ttyUSB0
            com_baud = 115200
        [[[runtimesettings]]]
            pubchannels = ToEmonCMS,
            subchannels = ToRFM12,
            nodename = emonTx4

Not sure why it’s called emonTx4, but anyway it found it. But again with less inputs…
Can I just copy/paste the auto-generated entry under [nodes] ?

    [[15]]
        nodename = emontx3_cm_15
        [[[rx]]]
            names = MSG, Vrms, P1, P2, P3, P4, E1, E2, E3, E4, T1, T2, T3, pulse
            datacodes = L, h, h, h, h, h, l, l, l, l, h, h, h, L
            scales = 1.0, 0.01, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 0.01, 0.01, 0.01, 1.0
            units = n, V, W, W, W, W, Wh, Wh, Wh, Wh, C, C, C, p
            whitening = 1

I guess I need to “match” it to the name defined under USB0 ?

I would really like to name the three emontx3 units so that I can make sense of them… is there a way to to that easily? I can see that the autoconf found “emontx3_cm_15” which is what it was called in the previous installation… (15) is the ID…
