Pimatic Plugin to access PV live logs using the Fronius Solar API. This plugin is based on node-fronius-solar.


You can load the plugin by editing your config.json to include the following in the plugins section. 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. The values properties interval and debug represent the the default values.

      "plugin": "fronius-solar",
      "interval": 60,
      "debug": false

Then you need to add a device in the devices section. Currently, the following device types are supported:

  • FroniusInverterRealtimeData: This type is to obtain the measurements data for an inverter device using the GetInverterRealtimeData service call of the Solar API V0/V1
  • FroniusComponentsData: This type is to obtain the measurements data for an PV system using an undocumented API service provided by the Fronius Data Manager provided with Symo inverters. In contrast to the regular Solar API Calls which do not require authentication, you may need to provide username and password properties to the options dictionary (if authentication has been enabled
  • FroniusPowerFlowRealtimeData: This type is to obtain the measurements data for an PV system using the GetInverterRealtimeData service call of the Solar API V1 which should work with Fronius Data Manager v3.4.2-1 (and higher)

As part of the FroniusInverterRealtimeData device definition you need to provide the deviceId which is the number of the inverter devices according to your PV system setup. You also need to provide host of the device providing Solar API, which is either your inverter (Fronius Galvo and Fronius Symo inverter models) or a Fronius Datamanager device.

For FroniusComponentsData and FroniusPowerFlowRealtimeData device configuration you can choose which attributes should be exposed by the device. See device-config-schema for details.

If you've configured your Fronius inverter to use power save mode, enter the threshold in watts at which power saving is activated. This helps to omit the nightly errors of the unreachable server.
