Uploading data from 3phase smart meter to PvOutput

[mcpoowl]

Hi guys,

I've recently installed some solar panels on my roof, and connected my smart meter to my Domoticz instance. Previously I just got 1 device (when looking at Power), and that was just the meter itself, but now it's totally different, and I'm struggling with uploading all the data to Pvoutput.

Now, I get 6 devices:
Usage L1
Usage L2
Usage L3
Delivery L1
Delivery L2
Delivery L3

Has anyone been able to upload this data succesfully to pvoutput. All the scripts I've found don't take the L1,L2,L3 into account, and thus won't work, and I guess there needs to be some aggregation.

Any tips would be highly appreciated!

Thanks in advance!

A dzVents solution could look like this.

When not yet familiar with dzVents please start with reading Get started Before implementing. Special attention please for
"In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents disabled' is not checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state."

Code: Select all

local stringVar = 'PVOutput'


return {
            on =    { 
                        timer = { 'every 4 minutes'},

Hi waaren,

Thanks for your reply and your script.

I don't think that script is going to work though, since my Usage L1 / Delivery L1 etc devices aren't actual P1 devices, but Usage, Electric devices, thus they won't have the .return1 function. See screen below.

NB: The Consumption device is a little test of mine, so forget that one

Looking at your screenshot, I see that your P1 "Power" is already an aggregate of the other devices. So no real modification needed compared to the script I use (apart from the fact that I have a Youless sensor to measure my production directly from the solarPanels kWh meter)
Can you try this one ?

Code: Select all

local scriptVar = 'PVOutput'

return {
            on =    { 
                        timer = { 'every 4 minutes'},
                        httpResponses = { scriptVar },

                    },

Hi waaren,

Thanks for sticking with me. I used your script, and edited the devices where needed, but I keep getting a 400 BAD REQUEST error. Maybe one of the values is too high? This is the log message I generated:

2019-06-23 20:24:00.201 Status: dzVents: Info: pvOutput: Calling PvOutput with HTTPS://pvoutput.org/service/r2/addstatus.jsp with data d=20190623&t=20:24&v1=86505&v2=0&v3=21439325&v4=127&v5=27.5&v6=234.1

//edit: When I post it as a GET request, I get more info:

Bad request 400: Energy value [86505] too high for system size [3720]

//edit2: When I add the c=1 and n=1 flags to the call, I get an 200 OK, so that works, but I'm not sure my data is correct?

Had another look but I seem to have messed up something in my own script or something has changed on the pvOutput side. Will have a look later this week and come back to you.

I indeed messed up something in my own script when I did some tests. Sorry for the confusion caused.
If you change the postdataAsString declaration to

Code: Select all

           local postdDataAsString = 
            'd=' .. os.date("%Y%m%d") ..
            '&t=' .. os.date("%H:%M") .. 
            '&v1=' .. P1.return1 + P1.return2 ..
            '&v2=' .. P1.usageDelivered ..
            '&v3=' .. P1.usage1 + P1.usage2 ..
            '&v4=' .. P1.usage ..
            '&v5=' .. round(temperature.temperature,1) .. 
            '&v6=' .. dz.utils.round(voltage.voltage,1) ..
            '&c1=1'

You get the results in pvoutput.

Thanks waaren, I'll check tonight, and post back tomorrow!
