Add two kWh meters

[MikeyMan]

Hi all,
Yesterday i installed my second inverter with a couple of panels.
Now i'm trying to add the numbers up to a total. Feel i'm getting close, but not working yet.

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

logging =
{
level = domoticz.LOG_DEBUG,
marker = 'Totaal Zonnepanelen',
},

execute = function(domoticz, device, item)

-- targetDevice = domoticz.devices(647) -- define as virtual custom sensor

local SolarEdge = domoticz.devices(9).counterToday
local Goodwe = domoticz.devices(632).counterToday
local Total = SolarEdge + Goodwe

domoticz.log('Totaalopbrengst Zonnepanelen counterToday: ' .. Total)

-- targetDevice.updateCustomSensor(Total)
domoticz.devices(647).updateCustomSensor(Total)
end
}

also tried a generic counter, but same error:

Can you not write values to a kWh custom device

[roblom]

I'm no expert but maybe it helps.. I think in the first attempt you try to update the "Totaal" device. In the second attempt you use the "test total" device but this is not a custom device I think
Why do you want too use a custom sensor? Maybe try .updateElectricity?

Is there another way to add a dummy device?

I'll give that a try thanks!

No luck yet:

Apparently it is not a generic custom sensor but a kwh device? So then you need to use updateElectricity()

and for the rfxmeter counter you need to use updateCounter()

Check the wiki, each type of device has its own update method.

Thanks for the tips, was a bit lost with the device types.
Change to Energy(Usage) type and this script:

Code: Select all

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

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = 'Totaal Zonnepanelen',
    },

    execute = function(domoticz, device, item)

        local SolarEdge = domoticz.devices(9).counterToday
        local Goodwe = domoticz.devices(632).counterToday
        local Total = SolarEdge + Goodwe

        domoticz.log('Totaalopbrengst Zonnepanelen counterToday: ' .. Total)

        domoticz.devices(648).updateEnergy(Total)
    end
}

And it seems to be working
Although now it shows current wattage instead of totals.

[MikeyMan]

Changed the type around again. Seems to be working for current value. Not so much for the daily totals yet

Code: Select all

return
{
    on =
    {
--        timer = {
--			'every minute'       
--                }
        devices =   {
            9,
            632
                    }
    },

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = 'Totaal Zonnepanelen',
    },

    execute = function(domoticz, device, item)

        local SolarEdgeToday = domoticz.devices(9).counterToday
        local SolarEdge = domoticz.devices(9).actualWatt
        local GoodweToday = domoticz.devices(632).counterToday
        local Goodwe = domoticz.devices(632).actualWatt
        local Total = SolarEdge + Goodwe
        local TotalToday = SolarEdgeToday + GoodweToday

        domoticz.log('Totaalopbrengst Zonnepanelen actualWatt: ' .. Total)
        domoticz.log('Totaalopbrengst Zonnepanelen counterToday ' .. TotalToday)

--        domoticz.devices(648).updateEnergy(Total)
        domoticz.devices(649).updateElectricity(Total,TotalToday)
    end
}

Strangely enough the log does show changing values:

Am i still using the device wrong?

Ah, WhToday makes more sense of the data

[willemd]

For a KWH device you have a choice between "computed" and "from device" when you click on the edit button of the device.
If it is "computed" then the daily value is calculated from the actual values, which is less accurate.
If you have counter values that you want to put on the device then it is best to choose "from device".

[roelvdh]

I am trying to use this. I have added 2 kWh values of 2 devices (solar batteries) into variable Totaal and want to put this total into a virtual sensor, idx 315, type=General, subtype=kWh. I tried your suggestion using:

Code: Select all

domoticz.devices(315).computed = Totaal

It runs fine but nothing happens to my virtual device. I just started using dzVents and do not yet understand some of the peculiarities. For instance: How can I find the usable arguments of the fuction domoticz.devices()? You would expect the Domoticz editor to provide such information. sqlite3 domoticz.db didn't help either. Normal road blocks for a starter, I suppose.

[FlyingDomotic]

Is Totaal Zonnepanelen a kWh counter?

[roelvdh]

No, but my 2 devices are and I am otherwise using the same code. Only, the virtual device containing the added kWh's is not hit.

Edit: The answer is in the docs, as always. I just had not found where to search for this answer. Solved.
