+
+# Fronius Symo monitoring with Netdata
+
+Collects metrics from the configured solar power installation from Fronius Symo.
+
+**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.
+
+## configuration
+
+Sample:
+
+```json
+{
+ "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`.

+
+[Fronius Symo 8.2](https://www.fronius.com/en/photovoltaics/products/all-products/inverters/fronius-symo/fronius-symo-8-2-3-m)
+
+The plugin has been tested with a single inverter, namely Fronius Symo 8.2-3-M:
+
+- Datalogger version: 240.162630
+- Software version: 3.7.4-6
+- Hardware version: 2.4D
+
+Other products and versions may work, but without any guarantees.
+
+Example Netdata configuration for node.d/fronius.conf. Copy this section to fronius.conf and change name/ip.
+The module supports any number of servers. Sometimes there is a lag when collecting every 3 seconds, so 5 should be okay too. You can modify this per server.
+
+```json
+{
+ "enable_autodetect": false,
+ "update_every": 5,
+ "servers": [
+ {
+ "name": "solar",
+ "hostname": "symo.ip.or.dns",
+ "update_every": 5,
+ "api_path": "/solar_api/v1/GetPowerFlowRealtimeData.fcgi"
+ }
+ ]
+}
+```
+
+The output of /solar_api/v1/GetPowerFlowRealtimeData.fcgi looks like this:
+
+```json
