"10" is the node number, the remaining data is the "payload" from your emonTx. It is 6 integer values represented as byte values in decimal.

You need to look at the (default?) emonTx sketch to see what the payload is, then look at where the values are copied into it to see if there is a multiplier.

The payload is defined:
    typedef struct { int power1, power2, power3, power4, Vrms, temp; } PayloadTX;
    PayloadTX emontx;

Then looking down to see how we get power1 (for example), we see:
    emontx.power1=ct1.realPower;
That power is in watts. But doing the same for Voltage, you see the voltage is multiplied by 100:
    emontx.Vrms=ct1.Vrms*100;
and temperature by 10:
    emontx.temp=(temp*10);

Yes, I looked at default emonTx sketch and I saw this structure:

typedef struct { int power1, power2, power3, power4, Vrms, temp; } PayloadTX;
PayloadTX emontx;

I have this output in minicom: 10 38 37 37 37 39 37 200 6 0 0 0 0

Isn't it too many values for this structure?

10 - node number

power1, power2, power3, power4, Vrms, temp - 6 integer values, but I have 12 values, exclude node number.

How to link them with each other?

I've attached an image. Is it correct?

No, sorry, this is what you have:

 
10 38 37 37 37 39 37 200 6 0 0 0 0

 Node ID

Two bytes for each integer! Power 1 = 38 + (256 × 37) = 9510 W.

Now it's clear for me! Thanks a lot!
