RE: Fronius inverter JSON integration - Erwin van der Zwart - 06.02.2022
Hi,
i have written a full script using the API a few years ago, i will post it later today when having access to my laptop…
RE: Fronius inverter JSON integration - Erwin van der Zwart - 07.02.2022
Code:
-- Load libs
require('socket.http')
require('json')
-- Set timeout
socket.http.TIMEOUT = 15
-- Get data from API
--data = socket.http.request('http://192.168.1.182/solar_api/v1/GetInverterRealtimeData.cgi?scope=System&collection=CommonInverterData')
--data = socket.http.request('http://192.168.1.182/solar_api/v1/GetInverterRealtimeData.cgi?scope=System&collection=CumulationInverterData')
--data = socket.http.request('http://192.168.1.182/solar_api/v1/GetInverterRealtimeData.cgi?scope=System&collection=3PInverterData')
data = socket.http.request('http://192.168.1.182/solar_api/v1/GetInverterRealtimeData.cgi?scope=System')
if data then
function sum(t)
local sum = 0
for k,v in pairs(t) do
sum = sum + v
end
sum = math.round(sum*0.001,2)
return sum
end
decdata = json.pdecode(data)
totaldata = decdata.Body.Data.TOTAL_ENERGY.Values
yeardata = decdata.Body.Data.YEAR_ENERGY.Values
daydata = decdata.Body.Data.DAY_ENERGY.Values
currentdata = decdata.Body.Data.PAC.Values
total = sum(totaldata)
year = sum(yeardata)
day = sum(daydata)
current = sum(currentdata)
previoustotal = storage.get('froniustotal')
if previoustotal then
if total > previoustotal then
grp.checkupdate('32/1/5',total)
previoustotal = storage.set('froniustotal', total)
end
else
storage.set('froniustotal', total)
end
grp.checkupdate('32/1/6',year)
grp.checkupdate('32/1/7',day)
grp.checkupdate('32/1/8',current)
endI use the storage to check the previous total, as the inverter can go in sleep mode when there is no sun, the API is not sending a valid value at that moment and i dont want to write a invalid value to my trend. So this part is needed if you might see strange values when removing it (:

how to get the infomation from this webseite script into the logicmachine virtual groupe adresse?
thanks

See Erwin's example in the previous post, it has exactly what you need.
RE: Fronius inverter JSON integration - mxcxpx - 09.02.2022
is ok. maybe you know how the procedere is from ip.fcgi to script.
i do not know but i will find it out
RE: Fronius inverter JSON integration - victor.back - 25.12.2022
Hi.
Is it possible to write this if condition in a modbus profile for automatic scale the values dependent on how big it is, for easier reading it?
Code:
-- Total power ever
r1, r2, r3, r4 = mb:readregisters(509, 4)
if r1 then
value = r1 * 0x1000000000000 + r2 * 0x100000000 + r3 * 0x10000 + r4
currentvalue = grp.getvalue('32/1/55')
if tonumber(currentvalue) ~= value then
if value > 999999999 then
units = 'GWh'
value = value / 1000000000
elseif value > 999999 then
units = 'MWh'
value = value / 1000000
else
units = 'KWh'
value = value / 1000
end
value = string.format('%.2f', value) .. units
grp.checkupdate('32/1/55', value)
end
endRE: Fronius inverter JSON integration - admin - 28.12.2022
You can use profile to read raw values then use a script to convert values to formatted strings. This cannot be done directly in the profile.
RE: Fronius inverter JSON integration - jose_dli - 20.09.2023
Hello,
I'm trying to create a modbus profile, but I'm having some trouble with scale factor: "address_scale". Without this scale factor, profile is working, but we get wrong values due to "live" multipliersd.
Testing register and his scale factor with the tool "read test", they are working properly. But I do not get response with both together in the profile.
Holding register: 40293, uint6--> 2260
Holding register: 40256 , int16--> -2
Tension on MPTT1: 2260 * 10^-2= 22.6 V; that is correct
I attach my profile, that it is created with map register of post #17.
Any help will be welcome.
RE: Fronius inverter JSON integration - admin - 20.09.2023
All scale registers must be added to the profile. Add "internal": true to scale register definition. Internal scale registers won't be visible in the mapping table, but will be read before reading other data registers.
RE: Fronius inverter JSON integration - jose_dli - 20.09.2023
Thanks, now it is working.
I attach the profiles in case anyone can use them as a basis.
Regards
