Module configurations are written in JSON and node.js is required.

The following node.d modules are supported:

This module collects metrics from the configured solar power installation from Fronius Symo. See netdata/conf.d/node.d/fronius.conf.md for more details.

Requirements

• Configuration file fronius.conf in the node.d netdata config dir (default: /etc/netdata/node.d/fronius.conf)
• Fronius Symo with network access (http)

It produces per server:

1. Power

• Current power input from the grid (positive values), output to the grid (negative values), in W
• Current power input from the solar panels, in W
• Current power stored in the accumulator (if present), in W (in theory, untested)

2. Consumption

• Local consumption in W

3. Autonomy

• Relative autonomy in %. 100 % autonomy means that the solar panels are delivering more power than it is needed by local consumption.
• Relative self consumption in %. The lower the better

4. Energy

• The energy produced during the current day, in kWh
• The energy produced during the current year, in kWh

5. Inverter

• The current power output from the connected inverters, in W, one dimension per inverter. At least one is always present.

Sample:

{
    "enable_autodetect": false,
    "update_every": 5,
    "servers": [
        {
            "name": "Symo",
            "hostname": "symo.ip.or.dns",
            "update_every": 5,
            "api_path": "/solar_api/v1/GetPowerFlowRealtimeData.fcgi"
        }
    ]
}

If no configuration is given, the module will be disabled. Each update_every is optional, the default is 5.

This module collects metrics from the configured heat pump and hot water installation from Stiebel Eltron ISG web. See netdata/conf.d/node.d/stiebeleltron.conf.md for more details.

Requirements

• Configuration file stiebeleltron.conf in the node.d netdata config dir (default: /etc/netdata/node.d/stiebeleltron.conf)
• Stiebel Eltron ISG web with network access (http), without password login

The charts are configurable, however, the provided default configuration collects the following:

1. General

• Outside temperature in C
• Condenser temperature in C
• Heating circuit pressure in bar
• Flow rate in l/min
• Output of water and heat pumps in %

2. Heating

• Heat circuit 1 temperature in C (set/actual)
• Heat circuit 2 temperature in C (set/actual)
• Flow temperature in C (set/actual)
• Buffer temperature in C (set/actual)
• Pre-flow temperature in C

3. Hot Water

• Hot water temperature in C (set/actual)

4. Room Temperature

• Heat circuit 1 room temperature in C (set/actual)
• Heat circuit 2 room temperature in C (set/actual)

5. Eletric Reheating

• Dual Mode Reheating temperature in C (hot water/heating)

6. Process Data

• Remaining compressor rest time in s

7. Runtime

• Compressor runtime hours (hot water/heating)
• Reheating runtime hours (reheating 1/reheating 2)

8. Energy

• Compressor today in kWh (hot water/heating)
• Compressor Total in kWh (hot water/heating)

The default configuration is provided in netdata/conf.d/node.d/stiebeleltron.conf.md. Just change the update_every (if necessary) and hostnames. You may have to adapt the configuration to suit your needs and setup (which might be different).

If no configuration is given, the module will be disabled. Each update_every is optional, the default is 10.
