PVOutput is a website in which you can share your solar production data. Home Assistant is an open source home automation solution that can be run in Raspberry Pi among other options.
Sharing photovoltaic (PV) production can help the community to learn, analyse and help make decisions regarding solar production plants investments, either residential or commercial.
STEP 1: GET APIKEY FROM PVOUTPUT.ORG
Go to pvoutput.org, register yourself and obtain an apikey, grab the key for later use
STEP 2: REGISTER YOUR SOLAR PLANT
Click on [Add System] button and register your plant data, at he end you’ll have a System Id which is needed for loading data later on
STEP 3: GET VARIABLES THAT HOLD PRODUCTION DATA
Depending the inverter or smart meter you have, an integration for Home Assistant is needed. The integration provides you sensor variables that you can use in automations and the like.
In my particular case, for a GoodWe inverter, I’m using an integration provided by the HACS community, called GoodWe Inverter Solar Sensor (UDP – no cloud), this integration provides direct UDP communication with the inverter not needing a cloud account and, because the direct communication, the integration is much more better.
STEP 4: CONFIGURE SCRIPT IN CONFIGURATION.YAML
Home Assistant has a “famous” configuration file in which you can set up a bunch of things, in this particular case we are setting a shell script that send data to pvoutput.org as follows:
shell_command:
pvoutputcurl: 'curl -d "d={{now().strftime("%Y%m%d")}}" -d "t={{now().strftime("%H:%M")}}" -d "v2={{states.sensor.goodwe_ppv.state|round(0)}}" -d "v4={{states.sensor.goodwe_house_consumption.state|round(0)}}" -d "v5={{states.sensor.goodwe_temperature.state|float}}" -d "v6={{states.sensor.goodwe_vgrid.state|round(0)}}" -H "X-Pvoutput-Apikey: 33f03........310a" -H "X-Pvoutput-SystemId: 8...7" https://pvoutput.org/service/r2/addstatus.jsp'
STEP 5: CREATE AN AUTOMATION
alias: pvoutput
description: ''
trigger:
- platform: time_pattern
minutes: /4
condition: []
action:
- service: shell_command.pvoutputcurl
data: {}
mode: single
The technical information to understand the command is explained here.
That’s all, hope it helps 🙂

Hello,
I added you rule, little bit converted to my own entities; but nothing is happening at pvoutput.
this is the code I have in the confuguration.yaml;
shell_command:
pvoutputcurl: ‘curl -d “d={{now().strftime(“%Y%m%d”)}}” -d “t={{now().strftime(“%H:%M”)}}” -d “v4={{states.sensor.power_output|round(0)}}” -H “X-Pvoutput-Apikey: 2….200” -H “X-Pvoutput-SystemId: 7…” https://pvoutput.org/service/r2/addstatus.jsp‘
is there anything else I have to do? I’m having a account at pvoutput, and also api key and systemic is correct

Yes, create an automation and execute the command every 5 minutes:
alias: pvoutput

trigger:
– platform: time_pattern
minutes: /5
condition: []
action:
– service: shell_command.pvoutputcurl
data: {}

I have it working but the voltage isn’t uploading.
Is there a way to see the values with are trying to uploaded?
shell_command:
pvoutputcurl: ‘curl -d “d={{now().strftime(“%Y%m%d”)}}” -d “t={{now().strftime(“%H:%M”)}}” -d “v1={{states.sensor.tdg2a4303y_energy_today.state|float *1000}}” -d “v2={{states(‘tdg2a4303y_output_power’)|round(0)}}” “v6={{states(‘tdg2a4303y_reactive_voltage’)|round(0)}}” -H “X-Pvoutput-Apikey: 2d” -H “X-Pvoutput-SystemId: 85” https://pvoutput.org/service/r2/addstatus.jsp‘

Go to Developer Tools|Templates and put your voltage template expression [{{states(‘tdg2a4303y_reactive_voltage’)|round(0)}}] in the editor and see if a value is displayed. I am curious about reactive_voltage, shouldn’t it be active_voltage? (reactive voltage is non zero mostly in industrial loads and the like I believe…)

When I type:
{{states.sensor.tdg2a4303y_reactive_voltage.state|round(1)}}
I get the result type: number and 234.7 as value

Hello,
Got problem with the curl command…. seems he don’t want to replace with the corresponding {{ sensors.mysenors.state}} value in any field (d,t,v1, etc…) If I exexucte for example :
curl -d “d=20220605” -d “t=10:03” -d “v1=1000” -d “v2=150” -H “X-Pvoutput-Apikey: 76501xxxxxx4835a9” -H “X-Pvoutput-SystemId: 9xxx2” https://pvoutput.org/service/r2/addstatus.jsp
it’s worling (from the shell exexcute in the file editor)
but I am trying for example :
curl -d “d={{now().strftime(“%Y%m%d”)}}” -d “t=10:02” -d “v2={{states.sensor.pvbrain_axpert_pv_power_total.state|round(0)}}” -H “X-Pvoutput-Apikey: 7650XXXXXX4835a9” -H “X-Pvoutput-SystemId: 9YYYY2” https://pvoutput.org/service/r2/addstatus.jsp
it’s no more working …. while in the template panel {{now().strftime(“%Y%m%d”)}} returns the correct date…..
Really strange.

Hi
I’ve cut & paste your command in my yaml and it seems your single quotes at the beginning and the end are not the correct character. If you have copied it from the post may have sense because sometimes html decoration changes the character map, just remove them and retype again from the keyboard, it just worked for me. I know because home assistant shows the content between single quotes in green colour.

Hi! Thank You for this great guide!
It is working but there is one problem: Victron VRM reads a different daily kw harvest than pvouput does. Today for example VRM has 19 kw daily harvest, but pvoutput is 21!
Any clou what could be causing this?
Have no problem with a little difference, but more than 10% is too much 😉

PVOutput allows sending data at a maximum slice of 5 minutes. If you send data at a rate higher that 1 value every 5 minutes, pvoutput uses the 5 minutes time slice. Are you sending power data every 5 minutes or at a less frequency rate? At the end, the energy is calculated as the sum of rectangles with a width of 5 minutes or more. The bigger the slice the higher the overhead. The most precisely calculation is when the time slice is near to zero (the definition of integral in differential mathematics calculation).
