Hi to everybody,
I am new user of openplotter.
I have connected my raspberry Pi 3B to my boat instrument and I can see data from NMEA 2000 network because I am using both RS485-CAN adapter and also CAN to serial USB (Arduino) adapter.
In both case I can see the same data at the same rate.
I have started to use also node-red and Influxdb to show and store the data however, at the beginning, I wanted to store and visualize my date at each second. After some tests I have seen that my update frequency of every data (wind, speed, GPS...) is near 2.5 second (see the CSV attached) while data rate of all data are different each other and some run at 10 Hz like GPS.
I have two question:
1. Is it possible to change this data rate or it is an hardware limit?
2. I know my data are stored locally and not in the cloud. Could anyone say to me where is the data folder and which is the format?
I want to thanks the community in advance.
Giuseppe
