Hi,
Currently I can only see KwH from the grid meter (one of the ET112's). Even though uint32 counters are used, I can still only see 1/10th of a KwH. This document that I have says that the scale should be 100 (the modbus register sheet, version 2.20) - how can I enable this or get a wH value ?
Thanks !
Hi @dewitpj, after rereading the list in excel, and its version in code [1], I think you can read up to 10Wh precision.
What are you seeing exactly? Always a 0 at the end?

Hi,
That is correct, I only ever see the counter increase in 10's:

That is the phase 1 from grid meter, top is latest. This is taken even minute with a +- 900w load on it.
It is worthwhile to note that I use address 2622 for these readings as they should contain a uint32 (all three phases in and out) - At the time I figured they might have higher resolution, appear not :)
Thanks !
