Hello everyone,
On site, I have a ION 9000 meter. When I open the web page, my Active Energy does not match precisely any of the Active Energy modbus registers.
I believe the register you'd want to use would be the 402700 for a meter like this.
Would anyone have an idea what is happening?
Thanks for your time.

Hello @Sork74 ,
Active energy is really one of four possible measurements, kWh del, kWh rec, kWh del + rec, kWh del-rec. The web page is using kWh Del-rec.
Depending on the CT ratios and system load, the energy values may have slight differences if system is accumulating energy. Modbus reads and web page reads may not happen at exactly the same time.
Regards,
Charles
