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.
Get the lcl-gateway tool and install it this way.
wget https://github.com/lechacal/lcl-gateway.py/releases/download/armhf/lcl-gateway_2.0.0_armhf.deb sudo dpkg -i lcl-gateway_2.0.0_armhf.deb
Edit the gateway.conf file to reflect your own settings.
sudo nano /etc/lcl-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] enabled = False hostname = emoncms.org apikey = --apikey-from-emoncms-goes-here-- node = 20 [influxdb] enabled = False 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] enabled = True directory = /tmp/
Insert the RPICT and run
The data will be stored in the /tmp directory. One file per day in csv format. Titled with the epoch time when it started.
Note that rebooting the pi will erase all that is inside /tmp. Use /home/pi/data if you need to preserve the data between reboots.
You can launch the gateway in the background using
sudo systemctl start lcl-gateway
If you prefer running the program by hand with some debugging to troubleshoot use the command below:
To make the gateway start automatically at boot time enter:
sudo systemctl enable lcl-gateway
