I've cruised this and other forums for resources but can't seem to get un-stuck. When Venus OS is loaded to the Pi it works fine, but I'm hoping to use the Pi for more than just that purpose, so I'm trying to use the docker container with Grafana.
The containers install fine, but no measurements are picked up:
When I run cat /dev/ttyUSB0 I get this result, so it looks like the MPPT 75|15 is outputting as it should:
I've tried a few options but none seem to achieve the desired effect:
The log isn't reporting any errors, but when debug us turned on, it looks like its rapidly connecting and closing connections through the USB cable.
Any advice would be greatly appreciated.
Here's my .yaml file:
Is it possible to get the data source into an existing grafana solution... without installing the composed file with grafana?
I'm trying to display a total for PV yield over a given period.
DBus values are available for /system/DC/PV/Power which I understand is the figure for all PV sources on the system, but I cannot work out how best to work out a yield/hr for this.
Suggestions welcome. Yield totals are the one thing that I am missing from Grafana that make VRM so useful.
Could someone tell me what the difference is between :
I am trying to create a panel that displays the sum of the 2 solar chargers. The issue is that "solarcharger/Pv/I" reports correctly for each instance, but the value retrieved for "system/Dc/Pv/Current" is more than double the cumulative value of the solar chargers?
Just set up VenusOS on an old raspberry pi I had and has been working well for all devices. Then I added the Grafana docker stack to another pi and it works really well for getting data about my 712 battery monitor, but my MPPT is not showing up. Any ideas?
I am currently setting up my RV with some Victron equipment (BMV, smart MPPT, etc) as a central element I use a pi with Venus OS.
My question is, is it possible to have Grafana/InfluxDB on the same device? I do not what to run a second pi just for that as energy consumption is always critical.
I am not a Linux guru and struggling installing the docker-composer on my Venus OS pi.
Thank you for any help and/or tips.
