Wrongtown Shower System

System Requirements

System Packages

Run the following to install system packages:

apt install espeak redis-server sqlite3 virtualenv espeak-ng

Python

The shower app currently requires Python 3.7 and will not run correctly on some newer versions of Python. To install Python 3.7, first install pyenv.

The first option for installing on pyenv Linux won't work on Raspberry Pi because the version of Linux running on the Pi is not compatible with Homebrew. Instead, use the "Automatic Installer option" by running the following:

curl https://pyenv.run | bash

Once pyenv is installed, install Python3.7:

pyenv install 3.7.17

Then switch to that version of python, either globally:

pyenv global 3.7.17

Or only for the shower project by navigating to the project directory and running:

pyenv local 3.7.17

Virtual Environment

To create and set up the virtual environment for the app, run the following within the project directory:

virtualenv -p python3.7 .venv
. .venv/bin/activate
pip install -r requirements.txt
python create_db.py

NFC Reader

verify nfc reader. Look for Sony Corp.

lsusb

enable nfc reader

python -m nfc

i.e.

sudo sh -c 'echo SUBSYSTEM==\"usb\", ACTION==\"add\", ATTRS{idVendor}==\"054c\", ATTRS{idProduct}==\"06c1\", GROUP=\"plugdev\" >> /etc/udev/rules.d/nfcdev.rules'
sudo udevadm control -R # then re-attach device

Seed Data

Enter the Sqlite shell for the app database:

sqlite3 app.db

Then import data from CSV files:

.mode csv
.import data/users.csv users
.import data/showers.csv showers
.import data/phrases.csv phrases

Run

main site

python app.py

workers

celery -A app.celery worker -l info -E
celery -A app.celery beat -l info

switch control

python hello_gpio3.py

nfc reader

python nfc_reader.py

systemd
