Detailed Description

One smart meter's readings.

The (first) four timing values are the start of reading; to have the end add .msDurRead.

Field Documentation

stmpS

uint32_t stmpS

Absolute time stamp for the current value.

This value and its supplements meterVal_t.ms, meterVal_t.hourOffs and meterVal_t.rTmTxt are updated at every Modbus read.

vals

float vals[18]

Compact and re-sorted meter readings.

These values are to be updated on every error-free meter reading (by Modbus, RS485 e.g.). The indexes are: /code 0..2 : U (L1, L2, L3) 3..5 : I (L1, L2, L3) 6..8 : P (L1, L2, L3) 9 : f 10, 11 : Wimp Wexp 12..14 : phi (L1, L2, L3) 15..17 : reserve (not used in R.115) /endcode
