# Solar Edge Status Updater
When placed in a cron job this uppdater will make an https call to a json api to retrieve the co2 savings and equivenant trees planted and overlay those numbers on a graphic and upload them to the website. 

# Dependancies
Python 3 and contents of `requirements.txt`.

The font `Biko_Regular.otf`.

A `.png` graphic to write text on.

The package direnv and the follwing changes to the user account:
* bash.rc (https://github.com/direnv/direnv/wiki/Python#bash)
* venv (https://github.com/direnv/direnv/wiki/Python#venv-stdlib-module)

If `ssh_host` is blank will copy file locally instead of scping file to sever. To scp valid sshkeys are required.


# Bulid Instructions
If want to run this by executing the code in the python venv envrionment, there is no need to make any changes after modifying the ```.env``` file.

assumes installed to `~/python/solar_edge`


```
cd ~/python
git clone http://git.elder-geek.net/fredw/solar_edge.git
cd solar_edge
cp env.sample .env
direnv allow
pip install -r requirements.txt
```

edit `.env` and update accordingly

add to user crontab to update site every 5 minutes
```
*/5   *     *   *  *    cd ~/python/solar_edge && direnv exec . python solar_edge.py > /dev/null 2>&1
```


# Create pyinstaller
Anytime you make a change to the ```.env``` file you will need to create and install a new copy if want to run this as a stand alone exceutable.
```
pyinstaller --onefile solar_edge.spec
cp dist/solar_edge ~/bin # user must have bin folder
```

add to user crontab to update site every 5 minutes
```
*/5   *     *   *  *    ~/bin/solar_edge > /dev/null 2>&1
```

# Combining Mulitple Sites
Each site will need it's own ```URL```. These should be numbed from one, in sequence in the ```.env``` file. IE ```URL1```, ```URL2```, ```URL3```...

# Backgrounds
There are multilpe backgrounds to choose from. They can be selected by changing the ```INFILE``` value. You can make more and add them in the ```datas``` section of ```solar_edge.spec```.
