Many thx!

Note: one typo in your script:

Code: Select all

local P1 = dz.devices('mySmartMeter)

should be:

Code: Select all

local P1 = dz.devices('mySmartMeter')

Many thanks Waaren!

After the update to Buster lua events uploading to PVoutput were not working any more due to socket.http problem.
Converted PVoutput upload to dzVents with your script and it works like a charm again.

Posted: **Tuesday 31 March 2020 19:51**

One question regarding your script Waaren:

It's uploading but I'm missing at least 3 kWh per day. I looked at the new and old script:

in the original LUA script 4 devices are used:

Code: Select all

local GenerationDeviceName = "Levering"         -- Device name of the Generated energy
local ConsumptionDeviceName = "Consumption"     -- Name of the energy device that shows calculated Consumption
local VoltageDeviceName = "DC Inverter 1"       -- Name of the voltage device that shows voltage of the inverter
local TemperatureDeviceName = "Buiten"          -- Name of the temperature device that shows outside temperature

In Waaren's dzVents script 3 devices are used:

Code: Select all

            local P1 = dz.devices('Power')
            local temperature = dz.devices('Buiten')
            local voltage = dz.devices('DC Inverter 1')

Apparently device 'Power' is a combination of both the 'Generation' and 'Consumption' device.
Unfortunately the upload to PVOut is in my case not correct anymore because the Power device gives lower amounts than the 'Levering' device (is my case the SolarEdge Inverter).

Remember that you can have internal usage. When you generate 1000W and use 1500W at the same time, your smartmeter will show an import of 500W and 0W generation. So when you log the generation at your inverter and compare these values with your smartmeter the smartmeter shows less.
For me it's not clear if this explains your findings but I thought I share it anyway.

Hi Waaren,
I am also using an Lua calculation script which calculates actual power consumption based on P1 output vs SolarGeneration. Both calculation and upload scripts broke. Dus to Lua 5.2-5.3 errors.
I got the calculation script working again, but not the pvoutput upload script. I am trying to figure out how to put in the correct values for Generation en Consumption.
Any help is much appreciated.

Thank you waaren for helping out.

I had my setup based on https://www.domoticz.com/wiki/Upload_en ... o_PVoutput.
This setup picks up my real generated power from my inverter, picks up my export/import from my SmartMeter(P1) and calculates my actual consumption (example: import+generation=consumption)

The upgrade to 2020.1 broke my scripts. The calculation script was easily fixed by remarking one line:

Code: Select all

-- local http = require("socket.http")

The upload to pvoutput script stopped working. I used the above example from waaren. Except it did not account for the calculation setup I use. Waaren helped me out with that. These are the differences I have now in my working setup:

Code: Select all

            local P1 = dz.devices('P1 Power')                   -- P1 output device
            local generated = dz.devices('SolarMain')           -- Output from SBSpot (SMA inverter)
            local consumed = dz.devices('Consumption')          -- Consumption virtual device
            local temperature = dz.devices('TempHumBaro')       -- Weather output from wheater device
            local voltageDevice = dz.devices('uac1')            -- Output from SBSpot (SMA inverter)

and for retrieved values:

Code: Select all

            dz.log('P1         : ' .. P1.sValue,dz.LOG_DEBUG)
            dz.log('generated  : ' .. generated.nValue .. ';' .. generated.sValue,dz.LOG_DEBUG)
            dz.log('consumed   : ' .. consumed.nValue .. ';' .. consumed.sValue,dz.LOG_DEBUG)
            dz.log('Temperature: ' .. temperature.temperature,dz.LOG_DEBUG)
            dz.log('voltage    : ' .. voltage,dz.LOG_DEBUG)

Mapping to the pvoutput values:

Code: Select all

                    'd=' .. os.date("%Y%m%d") ..
                    '&t=' .. os.date("%H:%M") .. 
                    '&v3=' .. round(consumed.WhTotal,1) .. -- consumed 
                    '&v4=' .. round(consumed.actualWatt,1) ..
                    '&v5=' .. round(temperature.temperature,1) .. 
                    '&v6=' .. voltage ..
                    '&c1=1'

This made my setup work again. Many thanks to waaren for helping me out.

I have attached the complete script.

I actually worked on the same.

Here are replacement dzVents-scripts for the old Lua scripts that are being used on the wiki.
These scripts work with the Consumption device that was also in the old Lua scripts.

So that means that when you have Solar Panels, the Consumption scripts calculates what the actual usage of electricity is by comparing the generated values from the solar panels with the used/returned electricity in the Smart Meter.

Can you help me further? Maybe the power value cannot be negative?

Only thing that seems strange is a negative consumption. Imho that can't be lower then 0. You are sending the 3rd value of consumed to PVoutput, and it seems it's 70 lower then the last time, which is why pvoutput does not accept the value.
My guess something is going wrong with your calculation script.
I'm still using the old Lua version. And as I have always something turned on in my house, I never get below 0 consumption.

Gr, Edwin

Here are replacement dzVents-scripts for the old Lua scripts that are being used on the wiki.
These scripts work with the Consumption device that was also in the old Lua scripts.

So that means that when you have Solar Panels, the Consumption scripts calculates what the actual usage of electricity is by comparing the generated values from the solar panels with the used/returned electricity in the Smart Meter.

Thanks,
These scripts did the trick easy. Just replaced the IDX, and it worked like a charm.

My system recently crashed so I thought lets try the new Dzvents script. It worked like a charm! The only thing is is that I think that the http response doesn't work. As far as I can see it's always 'PVOutput' instead of the actual response. How do I change that?

Posted: **Monday 06 July 2020 16:54**

I found out that it will post the response but only when in DEBUG mode. I added a check and if the response is not OK then it will put the HTTP response in the log.

So the log says sometimes:

Bad request 400: Invalid power value [-178]

I think it is because of a timing problem but am not sure. Anybody else have this problem?

What script do you use ? The one that was shared here does use LOG_FORCE so it should always show the response in the log.

pvoutput doe not like negative values in parm v1 or parm v2

I've used the version of tsybeck as a base, but I already customized it. I know that PVoutput doesn't like negative values but the question is how come they are negative. I've added some bug tracking (see below) but at the moment the sun is down so no data anymore

Code: Select all

        if item.isHTTPResponse then
			if item.statusText=='OK' then
				dz.log("Data successfully added to PVoutput")
			else
				dz.log("Error: the return from PVOutput was /n" .. item.data,dz.LOG_ERROR)
				dz.log('-- Energy generation (v1) = ' .. Solar.WhTotal .. ' Wh ', dz.LOG_ERROR)
				dz.log('-- Power generation (v2) = ' .. Solar.actualWatt .. ' W ', dz.LOG_ERROR)
				dz.log('-- Energy consumption (v3) = ' .. Consumption.WhTotal .. ' Wh ', dz.LOG_ERROR)
				dz.log('-- Power consumption (v4) = ' .. Consumption.actualWatt .. ' W ', dz.LOG_ERROR)
			end
		else
		....

Please share the complete script you are using now. It will make it easier to find why the script sometimes sends negative values.

Thanks for the help! But I found out that I have negative consumption values so I have to sort that out first.
