Add up current power production from more than one solarpanel system

If you want to see a total sum of more solar panel systems to monitor the current total production in watt... here is a code for that
Code: Select all
return {
on = {
timer = { 'every 1 minutes' }
},
execute = function(domoticz, item)
local bhPower = domoticz.devices(30) -- replace the numbers with the idx numbers from your devices or put -- in front of it to disable
local fhPower = domoticz.devices(8)
local ahPower = domoticz.devices(21)
local chPower = domoticz.devices(18)
local dhPower = domoticz.devices(24)
local ghPower = domoticz.devices(38)
local totalPower = domoticz.devices(56) --create a customsensor with "watt" as variable and replace 56 with that devices idx
local totalPowerupdate = tonumber(domoticz.utils.round((bhPower.WhActual + fhPower.WhActual + ahPower.WhActual + chPower.WhActual + dhPower.WhActual + ghPower.WhActual),2))
totalPower.updateCustomSensor(totalPowerupdate)
end
}

I used the above example to read the actual production of my 3 solarsystems. So I want to know the sum of the actual values
I made a dzVents-script and changed in Settings the status of LoggingLevel to Debug everything.
In the log of Domiticz I get this error:
2021-08-28 21:37:00.382 Error: dzVents: Error: (3.0.11) An error occurred when calling event handler Sum opbrengst
2021-08-28 21:37:00.382 Error: dzVents: Error: (3.0.11) .../var/scripts/dzVents/generated_scripts/Sum opbrengst.lua:15: attempt to perform arithmetic on a nil value (field 'actualWatt')
In the Wiki is told to change to actualWatt but I got the same error with WhActual.

Code: Select all
return {
on = {
timer = { 'every 1 minutes' }
},
execute = function(domoticz, item)
local OmnikPower = domoticz.devices(30) -- replace the numbers with the idx numbers from your devices or put -- in front of it to disable
local SMAPower = domoticz.devices(1249)
local GrowattPower = domoticz.devices(1268)
local totalPower = domoticz.devices(1277) --create a customsensor with "watt" as variable and replace 56 with that devices idx
local totalPowerupdate = tonumber(domoticz.utils.round((OmnikPower.actualWatt + SMAPower.actualWatt + GrowattPower.actualWatt),2))
totalPower.updateCustomSensor(totalPowerupdate)
end
}
This are the devices:
Any help is appreciated to get the script working!
Kind regards
