Example Using InfluxDB
This is a basic example to forward data to an InfluxDB database. Note this only covers a skeleton to start building your own application.
The RPICT series board must output as CSV for this to work.
Document edited using influxdb version 1.2 and python-influxdb version 4.0.
Server side hosting InfluxDB
Install InfluxDB as recommended. This link provides compiled executables.
Github link is here.
We will call this server hostname myserver for our example below.
For our example we need to create a database within influxdb. From a terminal on the influxdb hosting server issue the command below:
$ curl -i -XPOST http://localhost:8086/query --data-urlencode "q=CREATE DATABASE mydb"
If you want to install influDB on the Raspberrypi itself just follow this guide.
Install an InfluxDB Grafana stack on a Raspberrypi
We are proposing a basic script template which can be installed as below.
wget lechacal.com/RPICT/tools/lcl-gateway.py.zip unzip lcl-gateway.py.zip wget lechacal.com/RPICT/tools/gateway.conf
Edit the gateway.conf file to reflect your own setting. Content will be self explanatory.
Insert the RPICT and run
Run the Gateway script in background
You might need to keep the previous gateway program running in teh backgound.
sudo apt-get install screen
screen -d -m ./lcl-gateway.py
To stop it just run screen (provided you are only running one screen at a time).
Then press ctrl ^C.
