View source for Recording RPICT Serial stream on local file


This is to record the data from a RPICT series board in a plain CSV file that can be opened with excel or else later on.

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
 sudo apt-get install python-requests
 sudo mv lcl-gateway.py /usr/local/bin/
 sudo mv gateway.conf /etc/
 
Edit the gateway.conf file to reflect your own setting. 
 nano /etc/gateway.conf

In this file you should turn off Emoncms and Influxdb. Then turn on localsave. Also edit the directory if needed.

 [system]
 port=/dev/ttyAMA0
 baud=38400
 
 [emoncms]
 <span style="color: red">enabled = False</span>
 hostname = emoncms.org
 apikey = --apikey-from-emoncms-goes-here--
 node = 20
 
 [influxdb]
 <span style="color: red">enabled = False</span>
 url = http://10.10.15.26:8086/write   # https://corlysis.com:8086/write
 dbname = mydb
 user = token
 passwd = -optional-password-goes-here----
 measurement = rpict3t1           # Modify this to match your board
 
 [localsave]
 <span style="color: red">enabled = True</span>
 directory = /tmp/
 


Insert the RPICT and run

 lcl-gateway.py -d

The data will be stored in the /tmp directory. One file per day in csv format. Titled with the epoch time when it started.
