Energy metering with Eastron SDM630 v2 Modbus

Is it still working for you? Which firmware version of waveshare do you have?

I’ve got a SDM630 v2 Modbus, a Waveshare RS485/ETH connector and can use my Modbus manual via Perl scripts.

But using Home Assistant I get shitty values all the time. Using “rtuovertcp” I don’t get any values … using “tcp” I get random values

2021-10-27 17:05:08 ERROR (SyncWorker_3) [homeassistant.components.modbus.modbus] Pymodbus: modbus-gateway: Modbus Error: [Input/Output] No Response received from the remote unit/Unable to decode response

Thanks for any help!

I get this in the logs

Fixed, use float32

Hi all. Did you have any new FW to this SDM630 Modbus V2 to update ?

This solution is not working for me… I Always get the error:

[homeassistant.components.modbus.modbus] modbus waveshare1 communication closed

is there any solution for this issue?

Hi All,

I’ve also used the SDM630 for energy metering. Due to changes in HA, the configuration is now a bit different, and I made some hardware choices that work out quite well for me. This thread has been very helpful, and I wanted to return the favor by posting my working config here. I hope this is useful.

Hardware

I’ve studied electrical engineering, and I did the full electrical installation of my house. To me, the breaker box is no playground for hobby projects. Any mishaps here will cause serious issues and even fire. If something were to happen, even caused by something completely different, I do not want to have this discussion with my insurance. In effect that means that I run signal wires as short as possible and properly insulated inside the breaker box. All electronics goes outside the box, in another box.

I’m using 2 SDM630 V2s (and I will add a third later on). The RS485 is connected to both in parallel. I did not use any terminator resistors. Short wire runs and low bit rates will not require this. For this I used 0,5mm2 flexible wire that I twisted myself. You can go smaller, but that’s easy to damage and the insulation is not rated for voltages used inside the breaker box. This felt pretty sturdy and the insulation is also rated for high voltage.

One of the first things that needed to be done is to configure the SDM630 Modbus addresses. This can be anything between 1 and 247. Each device needs a unique address. I choose 100 and 101. By default this is 1. The chosen address is referred to as ‘slave’ in the modbus configuration. (or at least until some woke movement tries to cancel modbus). You’d also need to make sure that serial settings are good. I used the default setting: 9600,N,1. This needs to be matched by the RS485 to Ethernet bridge. I chose this, because the amount of data is small and slower is more reliable, especially since I’m not using terminator resistors on the RS485 bus.

As RS485 to Ethernet bridge I used this:

I have a POE enabled switch, so to power it I used a POE Splitter (I’ve used the 5V DC version, but 12V DC would also be OK):

The splitter was mutulated a bit in the proces, the alternative being a whole bunch of connectors, wires and screw terminals.

Both combined look like this:

Both are mounted in an ABS box (130h x 80w x 70d) outside the breaker box.

RS485 to Ethernet Config
For the RS485 to Ethernet bridge I was strugling with getting the software properly installed and working. Then, I noticed that the unit had a pretty good Web interface. So, there is no need to install any software to configure this. Out of the box, this device used DHCP and it got an IP address. Perfect for me. I have a separate DHCP enabled (with 10 year leases) IoT VLAN for these devices and HA.

Here are my serial port settings:

Here are my communication settings:

Home Assistant Config

I’ve moved modbus stuff to a separate file. To do that I added this to my configuration.yaml:

modbus: !include modbus.yaml

Here’s my modbus.yaml:
Please note that is contains everything twice (a and b) since I have 2 SDM630 V2’s connected.

The use of unique ID’s allowed me to set area’s and change names in the UI. I’ve used an online GUID generator to make these.

I also needed to have a couple of customizations to make stuff work in the energy panel, here’s my customize.yaml:

sensor.sdm630a_import_wh_since_last_reset:
  state_class: total_increasing
  
sensor.sdm630a_export_wh_since_last_reset:
  state_class: total_increasing

sensor.sdm630b_import_wh_since_last_reset:
  state_class: total_increasing
  
sensor.sdm630b_export_wh_since_last_reset:
  state_class: total_increasing

To be complete, customizations.yaml is a separate file. In the configuration.yaml this needs to be there:

homeassistant:
  customize: !include customize.yaml

@jghek this will work with SDM630 V2?

Yes. I have 2 V2’s connected. Here is a picture of one:

I’ve also changed my initial post. Thanks!

Great. Just one more question before I buy the equipments. To connect two SDM630 units I only need one RS485 to Ethernet unit, right?

Yes. You can actually have 247 modbus devices on a single RS485 bus. Just make sure you are setting each device to a unique address. Please note that what we call address on the SDM630 is called ‘slave’ in your HA modbus set up. The address in HA refers to the address of a value (acutally a register) within a modbus device.

Here’s a picture I made while adding a third SDM630.

All devices are connected in parallel, and I twisted the wire to make improve the signal transmission.

Hi,

How can we check if the connection is made between home-assistant and the unit.
Got the exact same one but cant get it to work so it seems?

Hi there.

I’m looking to buy a 3-phase meter to use with Home Assistant, I see that Eastron has released a “TCP” version of the SDM630 with an integrated ethernet port and Modbus/TCP. Has anyone tried it already?

Hi,

I have the EASTRON SDM630 MODBUS-MID V2
and I use Waveshare RS232/485/422 zu RJ45 Ethernet Konverter as a Gateway.

I am desperate. I cannot manage to get this two devices to work together or in Home Assistant.

First I tried to configure the gateway without the meter but I got no data even no random
noise data. Then I connected the power meter to it. The configuration looks fine. Both gateway
and power meter have the same serial properties:

  1. Baud rate: 9600
  2. Databits: 8
  3. Parity: even
  4. Stopbits: 1

I tried several tools like

  1. mbpoll (linux) → mbpoll.jpg
  2. ModScan → modscan.jjpg

Either no data is sent or the connection times out. I can ping the gateway so it should be
reachable.

I also tried to configure the gateway in Home Assistant. Same result. No data and even no
log entries although I got this in my configuration:

logger:
  logs:
    homeassistant.components.modbus: debug
    pymodbus.client: debug

I noticed that the small phone handset in the SDM630 display is missing. So I guess there is no
communication between both of them.

At the moment I am using a simple bulb and the 1p2w setting in the SDM630. Maybe that’s the
cause that the modbus is not working? Is modbus only active with a 3p4w setting?
I know this is a Home Assistant forum but maybe someone else had the same problems.

I would appreciate any kind of help and ideas.

Best regards
Goran

Hi Goran,

Have you got this to work in the end? I Was troubled with another type of Waveshare interface and got a little bit further by swapping the A and B signals around (seems like it was incorrectly labeled on the interface itself…). You may give that a try, though you may have tried that already of course.

Cheers,

Kim

Hi Kim,

I purchased an Modbus-To-USB dongle to test it directly at the computer.
It worked out of the box. So I guess the gateway does not work or cannot be configured properly.
I returned it.

At the end I found another solution:

I tried it and it works like a charme

Best regards
Goran

Thanks a lot, now i got it working. Herzlichen Dank nach dieser Anleitung funktioniert nun das Auslesen mit dem SDM630 Modbus v2 and a Waveshare RS485 to RJ45/Ethernet

@TomTomTom
I can confirm Modbus on the SDM630 works in the 1p2w settings as well.
Waveshare settings that I used:
Work mode: TCP Server.
Protocol: Modbus TCP to RTU

With that I tested if I could pull data using other tools first. With QModMaster I was able to pull data (0x04), Unit ID to what you set the SDM630 to, Start address 200, nr of registers 2, data format float, precision 3. This gave an output of 237 which is the L1 Voltage.

After this I got it to work on the Raspberry that has HASS installed. First I tried to replicate above using a Modbus integration in Node-Red as this makes it easier to play around with.

modbus:
  - name: "sdm630"
    retries: 10
    delay: 10
    message_wait_milliseconds: 1000
    timeout: 10
    type: tcp
    host: 192.168.2.40
    port: 502
    sensors:
      - name: sdm630_line_1_to_line_2_volts
        slave: 2
        address: 200
        input_type: input
        data_type: float32
        precision: 2
        unit_of_measurement: V
        device_class: voltage
      - name: sdm630_frequency_of_supply_voltages
        address: 70
        precision: 2
        input_type: input
        slave: 2
        data_type: float32
        unit_of_measurement: Hz

I had the feeling HASS only picks up Modbus configurations after a reload btw.

hello,

it’s my first time here so forgive any dumb mistakes.

but i had the same problems as descript above, i have the feeling it’s due to the fact the baudrate is to low for the modbus to function correctly, i have the same Waveshare modbus and the SDM630, and had the same problem.

I’ve set the baudrate on the SDM630 to 38400 and in the setting of the modbus.
mine is now working perfectly without losing any data or disconnection all the time. and its responding really quick.

here is my YAML and some pics of the settings that i have used.

Hello, how do you differentiate the individual electricity meters, any photos of the screens.
Thank you.
