For the past few months i’d been using the bash script kindly donated by @Bill.Thomson

> Hi Jeremy, Here’s what I use to send data from emonCMS to [PVOutput.org](http://PVOutput.org): #!/bin/bash PVO\_API='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' #your PVOutput.org API key PVO\_SYSID='xxxxx' # your PVOutput.org system ID FEED\_ID\_A='X' # id number of the feed you want to read data from FEED\_ID\_B='X' DATE=$(date "+%Y%m%d") TIME=$(date "+%H:%M") A=$(curl -s http://127.0.0.1/emoncms/feed/value.json?id=$FEED\_ID\_A) B=$(curl -s http://127.0.0.1/emoncms/feed/value.json?id=$FEED\_ID\_B) #A=$(wget -qO- http://1…

To get my emoncms data up in to PVOutput to have an alternative view on things.

But I found that in my setup the bash script occasionally dropped out and sent zero watts (both solar and usage) to PVOutput.

So I decided to try and re-write the whole thing in Python. I’m only a hobbyist coder at best so this has taken a little time.

I’ve tried to add some logging as well as some error checking.

Running this new python script alongside the bash script i’ve found mine doesn’t drop out when the bash one does. So an improvement of sorts.

I also added new functionality to grab the current temperature from DarkSky and also the current sun angle based upon your latitude and longitude.

There are comments within the code and a description up top. Hopefully this can help people out getting this to work in their system.

I decided to pull the data from [emoncms.org](http://emoncms.org) so that I could code this in my lunch hours. 😉

I’m sure you could amend the code to talk to your local instance if required.

```
#!/usr/bin/env python

# pvoutput_upload.py
# Pulls Solar and Home use data from your emoncms.org account and squirts the data up to PVOutput
#
# This can run on any internet host running Python3 and you should schedule the script to run every 5 mins
# You may be able to change to talk to your internal emonpi instance if you don't want it to go external.
#
# */5 * * * * /usr/bin/python3 /home/PVOutput/pvoutput_upload.py
#
# 5 mins is the shortest time period you can send to PVO (in donation mode), otherwise its 15 mins if you don't have a donation PVO account
# https://forum.pvoutput.org/c/donation-features
#
# Based on your longtitude and latitude the script also pulls down current tempearture (from DarkSky) and uses Pysolar to calculate the current sun angle.
# Use a website like https://www.latlong.net/ to calculate your lon and lat
#
# Note: For DarkSky you'll need to apply for a free API key via https://darksky.net/dev
# Note: The script is sending the sun angle data to v6 in PVO which is normally reserved for Voltage. But I do this so I see angle on the live displayed graph.

Nice work! ![thumbsup](https://community.openenergymonitor.org/uploads/default/original/2X/3/3c587556c0cc11389317c03a60788d77ceebd307.gif)

I rewrote it entirely in Python, but as I use a Modbus based meter, I didn’t post the update.  
(Figured it would be of little use to anyone not using Modbus)

This is just what I have been looking to do - many thanks for posting it.  
My problem is that I have no experience with coding, so have been trying to teach myself to use python so I can use this on my system - I’m struggling somewhat, but making some small progress, however I’m hoping you could help me with an error I can’t work out?  
When I try to run the program I get this error:  
File “/Users/xxxxx/pvout2.py”, line 197, in   
HOME\_USAGE, TEXT\_VALUES = get\_emoncms\_data(FEED\_ID)

File “/Users/xxxxx/pvout2.py”, line 92, in get\_emoncms\_data  
TOTAL = TOTAL + READING

TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’

Any help would be much appreciated,  
Cheers  
Andrew

Hi Andrew,

Welcome aboard!

That error is telling you that you’re trying to add a string to an integer.

I’m definitely not a Python expert, however in the first problem, that _multiple assignment_  
seems to be getting emonCMS data, but I can’t see from the context whether a string or a number is expected. I think you’ll have to put some debugging statements in to determine what the intention was.

In the second case, is the problem not in the line above `READING = (x[1])`? It looks as if READING is expected to be a number, is x[1] a number? If not, you will get the error. Maybe it needs conversion from a string to a number?

The person who can really clear this up is @Zarch (no relation, as far as I know!).

@Zarch & @Robert.Wall The problem seems to be with the collection returning 1 value with a None

Ok I have add a chekc at line 97 to check for a none type and procces line (98-100) if not detected,  
This seems to have fixed the issue

Dark Sky is end of life, is there an alternitive and can someone help update the script, maybe we can just disable the Darksky portion of the script ?

Try replcing

```auto
# Get temperature from DarkSky API
TEMP, CLOUD_COVER = get_darksky_weather()

```

with

```auto
TEMP = 0
CLOUD_COVER = 0

```

That should stop the call to dark sky and just put 0 into those values.

Hi Zarch,  
Thank you for the feed back, for some reason the python script was giving issue, like divide by zero and updates where missing from pvoutput.  
for this reason I have since moved to this script

> [@PVOutput from Emon feeds script](https://community.openenergymonitor.org/t/pvoutput-from-emon-feeds-script/21360):

> Hi all, [Here’s](https://cloud.workshopdirector.com.au/s/4tXwrKR6S4x8x3T) a script that will take values from your feeds and push them to [PVOutput.org](http://PVOutput.org) Enjoy \<?php #Global Variables // pvoutput API key here; OLD //$Feed\_api\_key = '091119xxxxxxxxxxxxxxxxxxxx4eb3ca'; // pvoutput API key here; $PV\_api\_key = '3c4a95xxxxxxxxxxab8007c'; // PVOutput.orgSystem ID here $SystemID = '12345'; //EMONCms Local IP Here $EMONCms\_Local\_IP = "192.168.15.208"; //EmonCMS Read API Key Here $EmonCMS\_Read\_API\_Key = "091119xxxxxxxxxxxxxxxxb3ca"; //Add CronTab Job once…

It works incrediably well and allows easy customization to add additiinal data,  
Thanks for you help and support on the pvoutput.py script, I had used it for many years.
