Input-Logger-OrangeZero

Log inputs status on a Orange Pi zero and plot graphs of your data. Its been verified to work with a orange pi zero with simple 8 inputs module (coming soon PCB). By changing the inputspins.yml file and making a corresponding GPIO inputs relation.

Requirements

Hardware

Orange Pi Zero
8 inputs module (coming soon PCB) or other module DIY

Software

Armbian
Python 3.4 and PIP3
OPi.GPIO
InfluxDB
Grafana

Installation

Install InfluxDB*

Step-by-step instructions

Add the InfluxData repository

$ curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -
$ source /etc/os-release
$ test $VERSION_ID = "9" && echo "deb https://repos.influxdata.com/debian stretch stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

Download and install

$ sudo apt-get update && sudo apt-get install influxdb

Start the influxdb service
```
$ sudo service influxdb start
```
Create the database
```
$ influx
CREATE DATABASE db_inputs
exit
```

*source

Install Grafana*

Step-by-step instructions

Add APT Repository

$ echo "deb https://packages.grafana.com/oss/deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

Add Bintray key

$ curl https://packages.grafana.com/gpg.key | sudo apt-key add -

Now install

$ sudo apt-get update && sudo apt-get install grafana

Start the service using systemd:

$ sudo systemctl daemon-reload
$ sudo systemctl start grafana-server
$ systemctl status grafana-server

Enable the systemd service so that Grafana starts at boot.
```
$ sudo systemctl enable grafana-server.service
```
Go to http://localhost:3000 and login using admin / admin (remember to change password) *source

Install Input-Logger-OrangeZero:

Download and install from Github and install pip3

$ git clone https://github.com/GuillermoElectrico/Input-Logger-OrangeZero.git
$ sudo apt-get install python3-pip

Run setup script (must be executed as root (sudo) if the application needs to be started from rc.local, see below)
```
$ cd Input-Logger-OrangeZero
$ sudo python3 setup.py install
```
Make script file executable
```
$ chmod 777 read_input_orangezero.py
```
Edit inputs.yml to match your configuration

Test the configuration by running:

./read_input_orangezero.py
./read_input_orangezero.py --help # Shows you all available parameters

If the error appears:

 /usr/bin/env: ‘python3\r’: No such file or directory

Use dos2unix to fix it.

 $ sudo apt install dos2unix
 $ dos2unix /PATH/TO/YOUR/FILE

To run the python script at system startup. Add to following lines to the end of /etc/rc.local but before exit:
```
# Start Logger
/home/pi/Input-Logger-OrangeZero/read_input_orangezero.py --interval 10 > /var/log/inputs-logger.log &
```
Log with potential errors are found in /var/log/inputs-logger.log
