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. Register description was taken from this source https://bg-etech.de/download/manual/SDM72D-M-DE.pdf Regards, jegaha

as I understand you tested this? :D

jegaha commented 5 years ago

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. DSC_2001_snippet

Hey I have an issue with the implementation of SDM72D-M reading in TASMOTA. Anyone can help with this? any suggestions? Maybe someone's already have compile tasmota bin and can share ?
i will appreciate it :-) Br Tomasz
