EmonTx RF12 Data Format Doubt [SOLVED]

Submitted by nkipreos on Mon, 02/02/2015 - 15:26

Hi Guys,

I am using the emontxv3 custom firmware (the one that came out of the box) and I am receiving the following information:

10 199 247 0 0 0 0 0 0 64 98 0 0

10 209 247 0 0 0 0 0 0 11 98 0 0

10 207 247 0 0 0 0 0 0 30 98 0 0

The 10 I can see in the code is the node identifier, and by what I read the first two measures after the 10 are the power associated to CT1. Here in Chile we have 220V and 50Hz as power supply, and I'm using a 100A current clamp.

I am guessing that the 2nd integer is the most significant one (because it doesn't change). So the measures would give me:

247=F7

207=CF

F7CF=63439W

It is only an electric kettle so I guess I'm getting this wrong.

Could you please help me?

It is signed, so 65536 - 63439 = not a long way from 2 kW. Flip the CT on its cable and see what you get.
