Wrong value

[edwin1234]

I have this script running:

Code: Select all

 on = { timer = { "every 1 minutes" }},     -- Change to your liking to 1,2,3,4,5,6,10,12,15 or 20   

   execute = function(dz, item)
        
       local Opbrengst  = dz.devices(1813)
       local Enphase     = dz.devices("Enphase Panelen - total").counterToday
       local Solaredge   = dz.devices("OpbrengstTotaal").counterToday
       
       Opbrengst.updateElectricity(dz.utils.round(Enphase + Solaredge), 0) -- Rounded to two decimals
        
   end
}

It adds the enphase and solaredge values
And writes to a dummy general kwh device
It gives today a value of 19 wh but should be 19kwh



How can i change this ?

multiply by 1000?

Code: Select all

Opbrengst.updateElectricity(Enphase + Solaredge)*1000, 0)

[waltervl]

updateElectricity(power, energy)
Power is W, energy is Wh.
But you should not use .counterToday as input value but .WhTotal.
This will give you at first huge total (as it will combine the total energy production of your solar panels) but you can delete that after a day from the month graph. And then it will show you nicely your total daily production.

I treid your script but got an error:

Error: dzVents: Error: (3.1.7) An error occurred when calling event handler zonnepanelenTotaal
2025-04-08 19:59:00.334 Error: dzVents: Error: (3.1.7) .../domoticz/scripts/dzVents/scripts/zonnepanelenTotaal.lua:11: attempt to perform arithmetic on a nil value (field 'WhTotal')

Code: Select all

 return { on = { timer = { 'every minute' }
},

execute = function(domoticz, item)

local Enphase = domoticz.devices(1185) -- Solar set 1, existing General kwh device
local Solaredge = domoticz.devices(905) -- Solar set 2, existing General kwh device -- Create manually a dummy kWh, Electricity (instant and counter) device$
local totalPower =  domoticz.devices(2460) -- total, to be used in Energy dashboard configuration


totalPower.updateElectricity( Enphase.actualWatt + Solaredge.actualWatt, Enphase.WhTotal + Solaredge.WhTotal )
end

}

What did i do wrong here?
Sorry i am a real script noob.

[waltervl]

It could be that one of the 2 solarpanel devices is not a General kWh devices that does not have a WhTotal value.

Can you make a screenshot of those 2 devices so we can see what the type is? Then you should adapt the function to get the correct Wh value.

Thanks for your help
Here are the photos



Values are zero now because its morning

[waltervl]

So the Enphase is a P1 meter, then you have to read other values. It could be Enphase.return1 or Enphase.return2 for the counter values depending on the input. And Enphase.usageDelivered for the Watt values.

[edwin1234]

Thanks for the answer,

Sorry but dont know how to do that or where to find these values.

[waltervl]

A P1 smart meter device is the wrong device to monitor a solar panel inverter, but you cannot do anything about this as the plugin developer decided that for you.
If you look at the graph on the Enphase log page sou see T1 and T2 graphs. Look which one the Enphase plugin is using and use that one.
In your script change line

Code: Select all

totalPower.updateElectricity( Enphase.actualWatt + Solaredge.actualWatt, Enphase.WhTotal + Solaredge.WhTotal )

into

Code: Select all

totalPower.updateElectricity( Enphase.usageDelivered + Solaredge.actualWatt, Enphase.return1 + Solaredge.WhTotal )

or if T2 is used:

Code: Select all

totalPower.updateElectricity( Enphase.usageDelivered + Solaredge.actualWatt, Enphase.return2 + Solaredge.WhTotal )

Thank you very much for the answer.
I am gonna try that

Hi waltervl,
The script doesnt give an error but it only shows the kwh from solaredge in total.
It doesnt add enphase with it.
I did try both methods .

[waltervl]

Can you post the outcome of API call (modify to real values: server-ip, port and IDX of Enphase p1 device)

Code: Select all

http://server-ip:port/json.htm?type=command&param=getdevices&rid=IDX

[edwin1234]

Forget to mention that i’m on an older domoticz version
(2021)

Code: Select all

		},

[waltervl]

Try it with Enphase.usage1 or usage2 instead of Enphase.return1 or 2
If you move to a newer version the Enphase integration will not use the P1 smart meter device anymore but normal general kWh devices, much better.

Ok , thank you

I will try that and let you know.

Hi Walter,

Its working

Thank you
