Adaption to sdm630??

[beireken]

Hello, Your library seems to be working fine. Thank you for sharing! I however am looking to also read from a 3phase sdm630. Can this library be easily adapted to add the 3phase registers?

Regards, Bart

You are try read sdm630 with this lib? If You can read parameters for first phase, then rest will be possible too. Look inside registers for sdm630: http://www.photovoltaikforum.com/download/file.php?id=58606

sdm630 registers for first phase are identical with sdm220...

so, You can add definitions for rest of registers, something like this:

#define SDM_VOLTAGE1                 0x0000
#define SDM_VOLTAGE2                 0x0002
#define SDM_VOLTAGE3                 0x0004
#define SDM_CURRENT1                 0x0006
#define SDM_CURRENT1                 0x0008
#define SDM_CURRENT1                 0x000A

etc... plus additional sdm630 registers if You want

OK, thx. I did not think it would be that easy...

So i adapted the library to this:

#define SDM120C_VOLTAGE                 0x0000                                      //V
#define SDM120C_CURRENT                 0x0006                                      //A
#define SDM120C_POWER                   0x000C                                      //W
#define SDM120C_ACTIVE_APPARENT_POWER   0x0012                                      //VA
#define SDM120C_REACTIVE_APPARENT_POWER 0x0018                                      //VAR
#define SDM120C_POWER_FACTOR            0x001E                                      //
#define SDM120C_PHASE_ANGLE             0x0024                                      //DEGREE
#define SDM120C_FREQUENCY               0x0046                                      //Hz
#define SDM120C_IMPORT_ACTIVE_ENERGY    0x0048                                      //Wh
#define SDM120C_EXPORT_ACTIVE_ENERGY    0x004A                                      //Wh
#define SDM120C_IMPORT_REACTIVE_ENERGY  0x004C                                      //VARh
#define SDM120C_EXPORT_REACTIVE_ENERGY  0x004E                                      //VARh
#define SDM120C_TOTAL_ACTIVE_ENERGY     0x0156                                      //Wh
#define SDM120C_TOTAL_REACTIVE_ENERGY   0x0158                                      //VARh

#define SDM630_VOLTAGE1                 0x0000                                      //V
#define SDM630_VOLTAGE2                 0x0002                                      //V
#define SDM630_VOLTAGE3                 0x0004                                      //V
#define SDM630_CURRENT1                 0x0006                                      //A
#define SDM630_CURRENT2                 0x0008                                      //A
#define SDM630_CURRENT3                 0x000A                                      //A
#define SDM630_POWER1                   0x000C                                      //W
#define SDM630_POWER2                   0x000E                                      //W
#define SDM630_POWER3                   0x0010                                      //W
#define SDM630_POWERTOTAL               0x0034                                      //W

This way i can keep both sdm120C and sdm630 registers. Just change the baud rate and go :) I should do some more testing when i have all 3 phases connected but it seems to work fine for the 3rd phase so i believe all will be good!

Thx a lot

so, when You are done all sdm630 registers, please create pull request and we add Your work.

I have started editing your work to add the sdm630 registers. However github is showing a lot of indent misalignments. Is this because we use different editors? I have tried atom and notepad++. Bot give different results. What editor are you using?

[reaper7]

I have notepad++ too but my fav is a notepad2-mod: https://github.com/XhmikosR/notepad2-mod
