Power Meter - SDM630 & additional values

[altbau9944]

Hello,

I have successfully integrated the EASTRON SDM630 via ESP32 and a Modbus RS485 adapter into my Openhab. The communication is handled via MQTT and everything works very well.

Now I want to read additional values from the energy meter.

1. frequency
2. phase_angle
3. import_active
4. export_active
5. import_reactive
6. export_reactive

Unfortunately I have problems to see these values in the Tasmota web interface. Can someone tell me how to adjust the "xnrg_10_sdm630.ino" to see these values?

Many thanks in advance...

Hi, try this code and if works well I will send a PR to integrate if Theo are agree.

You must copy all code and replace it in xnrg_10_sdm630.ino

Hello,

@pablozg: I did not manage to adjust the display with this INO file or any other adjustment in xnrg_10_sdm630.ino. No matter if I use dev 7.0.xx or the latest official release.

I also tried to get some support via Tasmota Support Chat. I no success. The search also takes a bit of getting used to.

Can somebody give me a hint how to display these values in the UI of the Tasmota interface?

• frequency
• phase_angle
• import_active
• export_active
• import_reactive
• export_reactive

Any feedback is welcome!!

[arendst]

Have a look at xnrg_08_sdm120.ino

[altbau9944]

Hello,

@arendst: I did but....

I'm afraid I have to come back to the subject. I only deal with the issue at the weekend, so I always get feedback later on.

I have used my time to try out some things. With the sensor.bin file an others as well. If I select the SDM120 in the Tasmota settings, no frequency will be displayed in the web interface, although it is entered in xnrg_08_sdm120.ino.

From the file xnrg_08_sdm120.ino: 52: 0x0046, // SDM120C_FREQUENCY [Hz] Energy.frequency[0] = value; // 50.0 Hz

124: case 6: 125: Energy.frequency[0] = value; // 50.0 Hz 126: break;

Maybe I'm making a mistake, but at the moment I can't get any further here. Would be great if I could get some help...

Regards

[arendst]

Did you try the suggested code in the first answer from pablozg?

All he asks you to do is copy all the text and paste it in the file xnrg_10_sdm630.ino replacing everything.

Then select the SDM630 serial interfaces like you did the sdm120 above and see what happens.

[altbau9944]

Hi Arendst,

Thank you very much for your effort and feedback!! Yes, I did. To recheck this once again, I paste to code in again and upload this to my NodeMCU V3. Rebbot and ...

These values are not visable.. 0x0024, // L1 - SD630_FASE_ANGLE [DEGREES] 0x0026, // L2 - SD630_FASE_ANGLE [DEGREES] 0x0028, // L3 - SD630_FASE_ANGLE [DEGREES] 0x0042, // TOTAL FASE ANGLE [DEGREES] 0x0046, // FREQUENCY [HZ] 0x0048, // IMPORT ACTIVE [W] 0x004A, // EXPORT ACTIVE [W] 0x004C, // IMPORT REACTIVE [VAR] 0x004E, // EXPORT REACTIVE [VAR]

Cheers altbau

I'm afraid your connection to the SDM630 is not correct. There appears to be no communication at all.

With logging set to 4 you should see at least this:

12:08:21 CMD: weblog 4
12:08:21 SRC: WebConsole from 192.168.2.1
12:08:21 CMD: Group 0, Index 1, Command "WEBLOG", Data "4"

12:08:24 DMP: 01 04 04 3F B7 CE D9 D2 4C

which represent the answers from the SDM630 when requesting to send each individual value.

The fact that screen only shows the default fields is a good sign there is no comms between the SDM630. To connect the SDM630 to an ESP8266 you will need a RS485 converter as documented here https://github.com/arendst/Tasmota/pull/2694#issuecomment-388309240

[altbau9944]

Hi arendst,

First of all I would like to thank you for your support.

I think the communication works between the SDM630, via the RS485 adapter to the ESP8266.

Take a look at the logging:

In general the needed values are not shown in the web-interface. As shown in my last picture.

By the way: I was able to add e.g. the Frequence in the Sonoff-Tasmota 6.6.0.11 3 month ago, but with the Tasmota 7.1.0 I have no success.

Nogmaals bedankt!!

Good Morning,

How can I manage, or who can contect to get some support here. I've tried to solve this issue this morning again and with no success...

I've adapted the xnrg_10_sdm630.ino file, as proposed by pablozg. But othing changed in the web UI...

@pablozg Can you support me??

Hi,

At first, thanks for great work for Tasmota OS.

I know that this topic is little bit old and some new features were added to xnrg_10_sdm630.ino code but I'm still looking for other measure parameters like 'Import Active' and 'Total Import'. I sow in code that a few variables are available but depends from SDM630_IMPORT define directive by default:

#ifdef SDM630_IMPORT
  0x015A,  //  +   +   +   kWh  Phase 1 import active energy
  0x015C,  //  +   +   +   kWh  Phase 2 import active energy
  0x015E,  //  +   +   +   kWh  Phase 3 import active energy
#endif  // SDM630_IMPORT

Is any serious reason why? I heard about Tasmota limitation regarding amount of cells but I don't believe...

Anybody know how to add missing variables to Tasmota-sensors?

EDIT. I changed xnrg_10_sdm630.ino code by comment lines with #ifdef SDM630_IMPORT / #endif SDM630_IMPORT and compile new Tasmota image. Now I see required variables. Probably the same effect might be reached by add #define SDM630_IMPORT in user_config_override.h ...

[seicento]

ifdef SDM630_IMPORT

0x015A, // + + + kWh Phase 1 import active energy 0x015C, // + + + kWh Phase 2 import active energy 0x015E, // + + + kWh Phase 3 import active energy

endif // SDM630_IMPORT

@panciunio Im strugling to get import kwh. I have tryed what you suggest but still no import? Maybe you could post your entire file?

Thanks

[funnyfrish]

SDM630_IMPORT does not work. Im still getting the same view without SDM630_IMPORT....

[arendst]

Energy Total equals SDM630 Import Active hence you won't see a difference.

Hi All, I my country anybody saying "Better is the enemy of good one!". It's mean if someone working properly - don't touch it!

I decided to upgrade my all Tasmota's network and of course, my Wemos D1 Pro connected to SDM630 stopped provide an information regarding Import Energy at all.

I started with official tasmota-sensors firmware and what I can see:

Okay... nothing happened... I had the same situation with Tasmota 8(9).x...

I downloaded newest development source archive and checked 'xnrg_10_sdm630.ino' file which contains section:

//#ifdef SDM630_IMPORT
  0x015A,  //  +   +   +   kWh  Phase 1 import active energy
  0x015C,  //  +   +   +   kWh  Phase 2 import active energy
  0x015E,  //  +   +   +   kWh  Phase 3 import active energy
//#endif  // SDM630_IMPORT

I assume, that's ok... I checked cases into SDM630Every250ms():

        case 19:
          Energy->import_active[0] = value;
          break;

        case 20:
          Energy->import_active[1] = value;
          break;

        case 21:
          Energy->import_active[2] = value;
          break;

look's good as well...

Compiled, flashed... result? the same...

No Import Active visible...

I tried to dig deeper... found 'configurations.md' file into 'energy_modbus_config' branch. Very interesting file which contains JSON structure for each data from energy measurement device, I founf SDM630 section and discovered that ImportActive variable is hidden into "User" section:

SDM630 {"Name":"SDM630","Baud":9600,"Config":"8N1","Address":1,"Function":4,"Voltage":[0,2,4],"Current":[6,8,10],"Power":[12,14,16],"ApparentPower":[18,20,22],"ReactivePower":[24,26,28],"Factor":[30,32,34],"Frequency":70,"Total":342,"ExportActive":[352,354,356],**"User":{"R":[346,348,350],"J":"ImportActive","G":"Import Active","U":"kWh","D":24}**}

The question is... how to check data from table "User" under Tasmota console and how to provide these information to MQTT if these are available?

Best Regards, panciunio

SDM630 ImportActive =Energy Total.

If you want more registers you will need to start using the new user configurable modbus driver. See https://github.com/arendst/Tasmota/pull/18413#issuecomment-1510131402

This is also more future proof where dedicated modbus drivers will be removed someday.
