Hello,
I've made some code to read the inverter.
You need to have:
- Script on device trigger
- Smart P1 meter called "Electra" (you can rename)
- IP adres of inverter (mine: 192.168.0.3)
- Uservariable: E_Today, E_Total, E_Total_Yesterday (Type: Integer)
- DummyDevice: Electra (Actueel + Teller) Type -> Levering (ID is needed for 'UpdateDevice')
Code: Select all
commandArray = {}
if (devicechanged["Electra"]) then --Smart meter every 10s update when daytime (shuts down automatically when no sun)
--Only try to read data from inverter when daytime
if timeofday['Daytime'] then
--print("start !")
local f = assert(io.popen("curl -s http://192.168.0.3/home.cgi" , 'r')) --Read data from webpage zeversolar
--print("f " .. f)
if (f ~= nil and f ~= '') then
--print("start read !")
local s = assert(f:read('*a'))
--print("Solar".. s)
if (s ~= nil and s ~= '') then --Check for valid value of response of read command
--print("s " .. s)
lines = {}
for t in s:gmatch("[^\n]+") do
table.insert(lines, t)
end
--local ID = lines[3]
--local Key = lines[4]
--local HW = lines[5]
--local SW = lines[6]
--local TimeDate = lines[7]
--local Key = lines[10]
local PacW = lines[11]
local E_Today = lines[12]
local Status = lines[13]
--print("PacW " .. PacW)
--print("E_Today " .. E_Today)
--print("Status " .. Status)
if Status == "OK" then
--print("Status == OK ")
commandArray['Variable:E_Today'] = tostring(E_Today*1000);
commandArray['Variable:E_Total'] = tostring(E_Today*1000 + uservariables['E_Total_Yesterday']);
commandArray[1] = {['UpdateDevice'] = 302 .. "|0|" .. PacW .. ";" .. uservariables['E_Total']}
end
end
end
f:close()
else
--Write current total to total yesterday for correct calculation tomorrow
commandArray['Variable:E_Total_Yesterday'] = tostring(uservariables['E_Total']);
local PacW_Zero = 0
commandArray[1] = {['UpdateDevice'] = 302 .. "|0|" .. PacW_Zero .. ";" .. uservariables['E_Total']}
end
end
return commandArray
Good Luck!
