Domoticz

If the problem still persists, could you add the offending line 58?

Hi,

I have a integrated P1 logger so i changed the script accordingly.
below the script the way i use it:

Spoiler: show

-- /home/pi/domoticz/scripts/lua/script_device_calculate_consumption.lua
-- This script collects the values below from Domoticz
-- * The Power and energy values (import and export) from a smartmeter
-- * The Power and energy values from a Solar power inverter
-- It then calculates the consumed power and energy from the values above with the formula's
-- * EnergyConsumption = EnergyGeneration + EnergyImport - EnergyExport
-- * PowerConsumption = PowerGeneration + PowerImport - PowerExport
-- It then updates a virtual device which displays the consumed power and energy in Domoticz

local ConsumptionDeviceName = "Elektra_verbruik" -- Name of the energy device that shows calculated Consumption

end

print(" ----- EnergyExportHigh = " .. EnergyExportHigh .. " Wh");
print(" ----- EnergyExport = " .. EnergyExport .. " Wh");
end

-- Calculate consumption
PowerConsumption = PowerGeneration + PowerImport - PowerExport
if Debug=="YES" then
print(" ----- PowerConsumption = " .. PowerConsumption .. " W");
end
EnergyConsumption = EnergyGeneration + EnergyImport - EnergyExport
if Debug=="YES" then
print(" ----- EnergyConsumption = " .. EnergyConsumption .. " Wh");
end

-- Update comsumption device in Domoticz
if devicechanged[EnergyDeviceName] then
update(ConsumptionDeviceName, ConsumptionIDX, PowerConsumption, EnergyConsumption, 1)
end

return commandArray

where line 58 is red

Activated it tonight, no changes made and i have no errors anymore??
Trying the upload now.
Wel upload goes wrong.. Seems like it uses Energy Import Low as value for the power.

The problem is

The current generated power is 3067693 W

This van be 2280W at the max. So I think you put in the wrong value.

I put the wrong value??
EnergyImportLow = 3067693 Wh, is used as current generated power is 3067693 W

first one is correct, the last one is not. but where do i change that? i guess i have to change the s value, but that would mean everybody with a P1 meter should do that?

I have taken a quick look so I might be wrong but it looks like you are using the same device for different things.

local GenerationDeviceName = "Elektra" -- Device name of the Generated energy
local EnergyDeviceName = "Elektra" -- Name of the energy device that shows imported and exported energy

The generated power can't be coming from the P1 as the smart meter only knows the exported energy. Between the energy generated by your solar panels and the exported energy that your meter shows is your internal consumption.

OK, So elektra has to become my solarpanels (SBFSpot)
I wil try that later. I thought i did that already causing another error. wil let you know, thanks for your reply.

GenerationDeviceName has to be your solar panels energy.
EnergyDeviceName has to be your smart meter.

Hi,

the script is like i thougt, i do have the solarpanels for the generation.
Still i have the same error: The power generation has to be 402. So i guess i have to alter some svalues. can you give me a hint?

It sounds very unlogic that you need to edit the svalues. Are the devices in domoticz displaying the correct values?
Did you correct the GenerationDeviceName in both scripts?

Excuses did not change the device in the upload script. Changed it correctly now it works accordingly. https://pvoutput.org/intraday.jsp?id=48861&sid=44499&dt

Sorry for being a n00b.

One last thing..
The voltage is now fixed at 232,5 volt? although before the sbfspot upload the voltage varies.
Where do i fix that??

In the upload script there is a VoltageDeviceName this needs to point at the name of the device in domoticz that shows the voltage.

Yes, obvious.
as you can see in the code parts i uploaded the voltage is given:
LUA: ---- The voltage of the inverter is 227.200 V
LUA: -- Voltage (v6) = 227.200V

And earlier:
LUA: ---- The voltage of the inverter is 228.600 V
LUA: -- Voltage (v6) = 228.600V

I did not change the device name so it should be right?
going to check it at home, i guess i messed something up in the SBF part.

I think i am going crazy..
I have got the device voltage up, and now night time the value is 0.
i get an error in the calculating script..

I wil let this run until i have a value again, but i guess this is not the right thing.

Normally the voltage that the inverter was running before it turned off will be kept until the inverter is woken up again the next morning. So it will never be set to zero. So your problem will be fixed tomorrow

Yesss. Thankyou.

Dear All

Will try to upload my P1 gas meter to Pvo...
For the nice graphs..
Only the Pi show no now value I did try to upload the meter with this script, only that is not working.
Because there is no now in the P1 gas, and all other sensors do have one...

Is there perhaps some that have a option for this upload?
Or a working script to upload to the V7 in Pvo?

Please ....
Fucked up with my settings for the upload of my usb P1 hardware... https://www.slimmemeterkabel.nl/
Is there some one that have a working example scriptfor me ...[ without api and other personal stuff ]
So i do not neet to replace peaces of the code.....

I try different times the wiki...
Replace parts of the code..[ more times ]
Only i do not understand it, and that is where i go wrong...

I am stuck with this P1 part...
And i do like to upload my P1 with domoticz...
Hope there is someone


And perhaps someone have the gas working, to upload it to Pvo?

What part you don't understand because the info provided in the wiki contains all the you need.
