Emoncms + Victron CCGX + My Battery App

borpin · 5 July 2020 19:34

Try doing sudo apt update first although another user has had an issue with this.

Hi,

Got myself into a bit of mess with the ‘sudo apt update’. I was running the 2018 emonbase sd card image and the discrete sampling software on my emontxv3 and the ‘sudo apt update’ stalled half way through

Tried to reboot and nothing…

So I reflashed the emonbase sd card with the lastest 2019 image and uploaded the latest continuous monitoring firmware onto the emontx. All the input were present and working.

I then used putty to complete the sudo apt update and it all updated and installed pymodbus. Will have a play this weekend and see if I can get the victron modubus registering on the input page.

I will keep you update

cheers

Its much easier to activate mqtt on the venus and use mqtt.
After that use nodered or any parser to get the desired values…

I might have a go with MQTT. I dont have node red running on anything atm.

I have pymodbus up and running now, but more errors. Can seem to find the answer to this one. See below.

My code in the emonhub config is this.

[[ModbusTCP]]    
    Type = EmonModbusTcpInterfacer
    [[[init_settings]]]
         modbus_IP = 192.168.0.80
         modbus_port = 502          # Portclient listens on
    [[[runtimesettings]]]
         rName = Battery State of Charge (System), Battery Voltage (System)
         register = 843, 840
         nReg = 1, 1
         rType = uint16, uint16
         # nodeid used to match with node definition in nodes section below. Can be set to any integer value not previously used.
         nodeId = 27
         # Channel to publish data to should leave as ToEmonCMS
         pubchannels = ToEmonCMS,            
         interval = 10

[[27]]
     nodename = Multiplus
     [[[rx]]]
       names = Battery State of Charge (System), Battery Voltage (System)
       datacodes = H, H
       scales = 1, 10
       units = %, V

any help would be much appreciated

cheers

HI all,

For those who have a CCGX connected to a multiplus/quattro and want to read registers via Modbus TCP and import them to the inputs page of emoncms. I have worked out the code that is required for the config file in the interfacers section of the emonhub.

As @James_Hill mentioned the unit ID must be included as there is multiple unit ID’s/slaves on the Victron VE Bus system. See below.

I wanted the SOC and charge/discharger power feed for the My Solar & Battery app.

[[ModbusTCP]]    
    Type = EmonModbusTcpInterfacer
    [[[init_settings]]]
         modbus_IP = 192.168.x.x
         modbus_port = 502         
     [[[runtimesettings]]]
         rName = Battery State of Charge (System), Input Voltage Phase 1, Grid Power, Battery Power, 
         register = 31, 4, 821, 843
         nReg = 1,1,1,1
         nUnit = 239, 239, 100, 100
         rType = uint16, uint16, uint16, int16
         nodeId = 27
         pubchannels = ToEmonCMS,            
         interval = 10

[[27]]
     nodename = Multiplus
     [[[rx]]]
       names = Battery State of Charge (System), Input Voltage Phase 1, Grid Power, Battery Power, 
       datacodes = H,H,h,h
       scales = 0.1,0.1,1,1
       units = %, V, W, W

Cheers

Gareth

Can someone help me pls? I am trying to set up Emoncms to access my CCGX, but I am unsure exactly where this config file gets edited in. Worried I might install in the wrong place. Can someone show their full config file & location please?
My Emoncms is on an Intel NUC, & pymodbus has been installed.

Thanks, Doug (safe in Overcast Sunny Australia! Hope Donnie Trump gets over his Covid? )

borpin · 3 October 2020 04:54

If you are trying to do the same as @gjones84, you are going to modify emonhub config.

In installing emoncms on an NUC, how did you do it and is emonhub running?

Dougo · 3 October 2020 05:25

Thanks Brian,
I installed from the Github image, & I think I disabled all the Pi bits. (I used the rPi user name etc as standard, cos it was easier!)
Emoncms is running fine, & it is getting data from my monitor. I Installed pymodbus, & that seems fine.
What I wish to achieve is to get the battery SOC from the CCGX, so that I can emulate the Victron Dashboard data (in some yet to be determined form).
My system is 2 of Solaredge 5Kw inverters, currently 15Kw of panels, thew Victron Charger/Inverter & Zenaji Batteries (Which are Lithium Titanate manufactured in Melbourne, Australia)

gjones84 · 3 October 2020 06:40

Hi Doug,

I have done this and it is all up and running and working fine. Once you have pymodbus installed and running. Log into your emonbase locally.

Then click the three bars at top left. Click emon hub. Select edit config. Scroll down to interfaces and insert my code. Restart and go to inputs and it should all be there .

Once you have that you can configure the My Solar Battery App.

Hope that helps.

Cheers

Gareth

borpin · 3 October 2020 09:19

Are you on a generic Linux install or a Pi one?

On to an NUC? Or do you mean you ran the scripts?

How? emonhub? HTTP? MQTT?

Unless I understand more how you have set emoncms up on the NUC I’ll not be able to help much as there are simply too many variables.

Thanks Brian, realising I am well out of my depth (but prepared to learn). I am a hardware man!
I realise that I do not know how all the s/w fits together, except in a basic way.

regards, Doug

borpin · 3 October 2020 18:07

You didn’t say how you did the install.

But, when you did the install, you did not install emonhub. You will need to do that.

I think you can just clone the emonhub repo and run the install. As I do not know where or how you installed the scripting part of emoncms, I can’t advise where to install it to.

On the Pi systems that is all in /opt/openenergymonitor.

gjones84 · 3 October 2020 19:13

The standard pi one

borpin · 4 October 2020 08:54

Yes much simpler as emonhub is installed by default.

John_P · 15 April 2023 15:08

Hi Gareth,

I realise that this thread is quite old now, but I’m trying to do exactly the same as you did. It seems to run MODBUS successfully, but then I get this in the logfile:

I’d be grateful if you had any advice!

Thanks,

John.

borpin · 15 April 2023 17:30

Is your system fully updated?

John_P · 16 April 2023 14:01

Yes - just done a full system update and get the same error

gjones84 · 16 April 2023 14:29

Hi. Some time ago I did this. I remember it being a PITA when I did it.

Tbh with all my experience now. I can help you muddle way through the modbus stuff but the best way to parse data from your victron system is via mqtt

Download this and install of your pc.

Then connect to your venus device and take a look at which topics you wish to pull out.

Then use the venus os large image with node red and you can pull the topics out using the installed victron nodes or via mqtt topics and ping them straight into emon device piece of cake.

Its easy, robust and reliable.

Cheers

Gareth

John_P · 16 April 2023 16:04

Thanks Gareth - I came to that conclusion too, but I’m not running Node Red, and am having problems with that too! See here:

gjones84 · 17 April 2023 05:55

Could you do a quick sketch of of your system please? Inverter/charger, battery, bms, gx or venus device and comms?
