Emoncms + Victron CCGX + My Battery App

Integrations
10

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
