So I found instruction how to switch COM driver in here: Ĭompile and install the common usb serial driver module # makeĮnsure that thecdc-acm module is not loaded (assumig that it is not needed) # echo blacklist cdc-acm > /etc/modprobe.d/nf Currently it is set as this:Ĭrw-rw- 1 root dialout 166, 0 Jun 8 12:54 /dev/ttyACM0Īpparently in order to work it has to be this:Ĭrw-rw- 1 root dialout 166, 0 Jun 8 12:54 /dev/ttyUSB0
I did some extensive research before asking this question and I was actually able to find out that the problem is actually within the Serial driver in Raspberry. This Node-Red flow uses the Modbus (node-red-contrib-modbus extension) nodes which are set to proper serial port but it doesn't receive any data (although the node says "connected") I have Node-Red server installed in Pi and have a prepared dashboard according this project: These two devices are connected via USB to serial cable (Bus 001 Device 005: ID 04e2:1411 Exar Corp. Next to it I have Raspberry Pi which I would like to use to read the stats from SCC. I have Solar Charge Controller Epever Tracer which is capable of communicating via RS485. This is my first post in stackoverflow so I hope community can help me:-)
