nrf24-Logger-Pi

Log nrf24 devices with nfrlite arduino librarie on a Raspberry Pi and plot graphs of your data. Its been verified to work with a raspberry pi with a Attiny gateway into nrflite network vía i2c comunication (coming soon PCB and sketch). Used I2C port in the Raspberry Pi.

Requirements

Hardware

Raspberry Pi
Attiny gateway I2C (coming soon PCB and sketch) or other module DIY

Software

Raspbian
Python 3.7 and PIP3
python3-smbus
InfluxDB
Grafana

Prerequisite

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_nrf24
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 nrf24-Logger-Pi:

Download and install from Github and install pip3

$ git clone https://github.com/GuillermoElectrico/nrf24-Logger-Pi.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 nrf24-Logger-Pi
$ sudo apt-get install python3-smbus
$ sudo python3 setup.py install
```

Make script file executable

$ chmod 777 read_nrflite_pi.py
$ chmod 777 setup_nrflite_pi.py

Edit setup_nrflite_pi.py to match your configuration and launch (if necessary to configure attiny)
```
./setup_nrflite_pi.py
```

Test the configuration by running:

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

To run the python script at system startup. Add to following lines to the end of /etc/rc.local but before exit:
```
# Start nrf24 Logger
/home/pi/nrf24-Logger-Pi/read_nrflite_pi.py > /var/log/nrflite-logger.log &
```
Log with potential errors are found in /var/log/nrflite-logger.log
