I did not install a fronius binding - instead I am using the http binding to fetch the data from the fronius.
In order to do this you need to install the http binding form the Paper UI, then place three lines in your /services/http.cfg file, where you specify the IP address and update intervall of your fronius, like:
froniusrtd.url=http://192.168.1.59/solar_api/v1/GetPowerFlowRealtimeData.fcgi?Scope=System
froniusrtd.updateInterval=5000
format=false
Then you put one line for each value to fetch in your home.items file (I am using a group gPV to display all collected fronius data):
// Fronius via HTTP
Number PV_Load “Aktueller Verbrauch [%.1f W]” (gPV) { http="<[froniusrtd:5000:JSONPATH($.Body.Data.Site.P_Load)]" }
Number PV_Current “Aktuelle Produktion [%d W]” { http="<[froniusrtd:5000:JSONPATH($.Body.Data.Inverters.1.P)]" }
Number PV_DaySum “Tagessumme [%0f Wh]” { http="<[froniusrtd:30000:JSONPATH($.Body.Data.Inverters.1.E_Day)]" }
Number PV_YearSum “Jahressumme [%0f Wh]” { http="<[froniusrtd:30000:JSONPATH($.Body.Data.Inverters.1.E_Year)]" }
Number PV_Total “Gesamtsumme [%0f Wh]” { http="<[froniusrtd:30000:JSONPATH($.Body.Data.Inverters.1.E_Total)]" }
Number PV_Grid “Bezug vom Netz [%.1f W]” (gPV) { http="<[froniusrtd:5000:JSONPATH($.Body.Data.Site.P_Grid)]" }
Number PV_Akku “Leistung von Batterie [%.1f W]” (gPV) { http="<[froniusrtd:5000:JSONPATH($.Body.Data.Site.P_Akku)]" }
Number PV_PV “Leistung vom Dach [%.1f W]” (gPV) { http="<[froniusrtd:5000:JSONPATH($.Body.Data.Site.P_PV)]" }
Number PV_Battery “Batterieladestand [%d Prozent]” (gPV) { http="<[froniusrtd:30000:JSONPATH($.Body.Data.Inverters.1.SOC)]" }
Number PV_Self “Eigenverbrauch erzeugter Leistung [%.1f Prozent]” (gPV) { http="<[froniusrtd:5000:JSONPATH($.Body.Data.Site.rel_SelfConsumption)]" }
Number PV_Autonomy “Autonom zu [%.1f Prozent]” (gPV) { http="<[froniusrtd:5000:JSONPATH($.Body.Data.Site.rel_Autonomy)]" }
Hope it works for you!
