combine power to single sensor

Hi all,
I have this script and it works so far, no errors in the log.
I want to combine the power of three sensors and display that in a dummy sensor (kWh) So far I can see in the log the combined/totalled power.
The sensor 'Totaal Kwh Growatt' is updating but there is no value displayed. If I look in the device tab at this sensor then I do see under data the values changing.
What am I doing wrong here?
Code: Select all
return
{
on =
{
devices =
{
499, 503, 507
}
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = 'totaal vermogen',
},
execute = function(dz)
local L1 = dz.devices(499).actualWatt
local L2 = dz.devices(503).actualWatt
local L3 = dz.devices(507).actualWatt
local combinedUsage = dz.devices('Totaal Kwh Growatt')
local totpower = ( L1 + L2 + L3 )
combinedUsage.update(totpower, WhActual)
dz.log('# totaal vermogen = '..totpower..'')
end
}

Code: Select all
combinedUsage.update(totpower, WhActual)
What is WhActual? I think you have mixed up the values.
I think you have to send totpower = 0 but not sure this works for this device.
WhActual = L1+L2+L3
And then use other way around
Code: Select all
combinedUsage.update(WhActual, totpower)
POWER = current power = WhActual
ENERGY = Integer, total cumulative energy in Watt-hours (Wh) = totpower = 0
Also WhActual is a DzVents function name so perhaps better to call it WhActualCombined
Alternatively you can make a dummy Electrical Usage devive
https://www.domoticz.com/wiki/Dummy_for ... lectricity
https://www.domoticz.com/wiki/DzVents:_ ... tric_usage
That needs only 1 parameter
.updateEnergy(energy)
eg
Code: Select all
WhActualCombined = L1+L2+L3
combinedUsage.updateEnergy(WhActualCombined)

Created a new dummy "Electrical Usage device " and that did the trick. The old one was an "General kWh"
I was probably to much focused on the script and didn't paid attention to the sensor it self.
Thanks Walter, you seem to be al over the forum
And the final script
Code: Select all
return
{
on =
{
devices =
{
499, 503, 507
}
},
logging =
{
level = domoticz.LOG_ERROR,
marker = 'totaal vermogen',
},
execute = function(dz)
local L1 = dz.devices(499).actualWatt
local L2 = dz.devices(503).actualWatt
local L3 = dz.devices(507).actualWatt
local combinedUsage = dz.devices(511)
local totpower = ( L1 + L2 + L3 )
combinedUsage.update(0,totpower)
dz.log('# totaal vermogen = '..totpower..'')
end
}

in my case i have a error.
i create this dummy for the picture.
Error: EventSystem: in KW monitor: [string "return ..."]:13: attempt to index a nil value (global 'domoticz')

You have to create a dummy device type "Usage (Electric)". Not a counter or electric instant and counter.

And the script is in dzvent, forgot to mention.

return
{
on =
{
devices =
{
178, 175, 172
}
},
logging =
{
level = domoticz.LOG_ERROR,
marker = 'totaal vermogen',
},
execute = function(dz)
local L1 = dz.devices(178).actualWatt
local L2 = dz.devices(175).actualWatt
local L3 = dz.devices(172).actualWatt
local combinedUsage = dz.devices(214)
local totpower = ( L1 + L2 + L3 )
combinedUsage.update(0,totpower)
dz.log('# totaal vermogen = '..totpower..'')
end
}
i just replace my idx. i creata that dummy Usage(electric). No error now, but no results .

This script will count the actual Watt that the solar panels are creating at the moment. So if the solar panels are not working the value will be 0

I want to know my consumption. theoretically shouldn't it also work with the consumed value?
i use shelly 3em to monitor consumption. I have no panels, so the production is zero. I thought it could also work for the total energy consumed
thx

That should also work, what is the log telling you? Go to the log page and typ in the right top corner totaal
(that is stil in you're script)
Also the "last seen time stamp on the new dummy, is this updating?

the dummy is time out
no error in log.
nothing if i write in search box :totaal
if i make any modification in the sript, in the log apear this :
2023-09-21 12:08:50.815 Status: EventSystem: reset all events...
2023-09-21 12:08:50.816 Status: dzVents: Write file: /home/XXXX/domoticz/scripts/dzVents/generated_scripts/Script #1.lua

Seems the script is not triggered. So check the devices you configured in the first lines.
