Hello
I have a Victron system and I'm very satisfied with it. Runs really good!
I have a RasPi attached (running a webcam) and now additionally I want to monitor the actual data of the solar system.
I found this program: https://github.com/oekoluk/Victron-Data-Reader-and-Logger/blob/master/lesenschreiben.php and made the connection to the BMV-700 via USB.
On
# ls /dev/serial/by-id/usb-VictronEnergy_BV_VE_Direct_cable_VE*
I get a nice answer:
# /dev/serial/by-id/usb-VictronEnergy_BV_VE_Direct_cable_VE3MENQ-if00-port0
So my Raspi detects the BMV-700 with the name VE3MENQ.
But running the program I get the following lines:
14.12.2018 19:55;0;;;
14.12.2018 20:00;0;;;
14.12.2018 20:05;0;;;
14.12.2018 20:10;0;;;
...
No data. Just one zero. Any idea, why this happens? What to change to get the data?
