Hey reaper7,
thank you for your great work. It was a great pleasure for me to take and extend your library to use my SDM72 Energy Meter.

Yes, I managed to make it run. My only problem with the combination of D1 mini/RS485/SDM_72 was that it only runs in HW serial mode. My first test setup with Arduino/RS485/SDM_72 runs in both HW and SW serial mode. Maybe a timing problem or a weak timing source on the D1 mini.

The hardware is now mounted on a 3D-printed carrier and is counting and monitoring the energyconsumption of the EVCS.
