A pimatic Plugin for SolarView (SV), a data logger for PV systems:

• German homepage: http://www.solarview.info
• English homepage: http://www.solarview.info/Solarlogger_en.aspx

SV is capable of gathering data from up to 9 inverters and additional meter points which may be used to monitor the in-house consumption of solar energy, for example. SV is a vendor-neutral solution which supports a large number of inverter models from various vendors. It is available for Fritz!Box, Raspberry PI, and Windows.

To be able to read the SV data records with pimatic-solarview, the TCP-Server option must be enabled by adding the -TCP <port> option to the SV start script. See section TCP-Server of the SV Installation Manual.

You can load the plugin by editing your config.json to include the following in the plugins section. The properties host and port denote the hostname (or IP address) and port of the SV TCP server. The property interval specifies the time interval in seconds for updating the data set. For debugging purposes you may set property debug to true. This will write additional debug messages to the pimatic log.

{ 
   "plugin": "solarview"
   "host": "fritz.box"
   "port": 15000
   "interval": 10
}

Then you need to add a device in the devices section. The plugin offers three device types:

• SolarViewInverterSimple: This type of device provides status data on the accumulated energy earnings (today, this month, this year, total) and the current power produced.
• SolarViewInverter: This type of device additionally provides you with data on AC voltage, amperage and inverter temperature readings.
• SolarViewInverterWithMPPTracker: This type of device is for PV systems with a MPP tracking system. It additionally provides you with data on voltage and amperage for up to three DC strings.

As part of the device definition you need to provide the inverterId which is a digit [0-9] to identify the number of the inverter attached to the SV logger (see example below). The digit 0 depicts the sum of all inverters attached to the SV logger.

{
    "id": "sv1",
    "class": "SolarViewInverterSimple",
    "name": "PV System",
    "inverterId": 0
}

Hints: If you wish to hide some attributes this is possible with pimatic v0.8.68 and higher using the xAttributeOptions property as shown in the following example. Using the xLink property you can also add a hyperlink to the device display.

{
    "id": "sv1",
    "class": "SolarViewInverterSimple",
    "name": "PV System",
    "inverterId": 0,
    "xLink": "http://fritz.box:88",
    "xAttributeOptions": [
        {
          "name": "currentPower",
          "hidden": true
        }
    ]
}

There are a few things I am planning to add in the short term:

• Add support for additional meter points, for example, for an additional power meter to monitoring the in-house consumption of solar energy.
• Currently, the update cycles also run at night. This could be limited to daylight hours even though the load caused by the update cycles should be fairly low.
• Possibly add localized names for attributes if this is supported by pimatic.
