Hi Paul,
The problem with the production “direction” ist that ActivePower can be negative. Not good for a production meter but also physically correct. So I took a modified SDM630 which does not allow negative values for production.
With consumption vice versa. Now OpenEMS shows 2 meters but uses the same hardware meter. That´s ok for my purpose.
I have to say that I am still struggeling with energy flow and the different meter types make it even more complicated.
But I am happy with my solution even if it is not out of the box any more.
It´s the same discussion that @phfeustel kicked off in this thread. By the way: his small table helped me to understand energy flow the right way.
Regards,
klinki
