Hi,
i have now two cerbo gx running. So i have two installations in VRM. I could see data from both installations in VRM.
I use venus-docker-grafana to load the data into a local influxdb. All Tables has the field portalID so it should work with different installations. (Each installation has its own portalID).
But in the Dashboard it only transfers data from the first installation.
What do i missing?
Regards
Is the data not getting into InfluxDB, or are you not able to display?
If i look into my InfluxDB in system/Connected i only found my first installation. The Venus-Docker-Grafana-Server only transfers the first installation.
I know there is no official support for the Venus-Docker-Grafana-Server, but did anyone use this with two or more installations?
G'day Ulrich.
I have managed to get multiple installations to display. I'm very much an amateur and learning so please understand that.
I have about 20 installations in the VRM account and what I did was to just select the ones I wanted to display in the admin interface at http://localhost:8088.
After that, the systems I selected here became visible in Grafana as each system sent data to VRM.
Then in a Grafana query, under the Options, select "WHERE" and "=" then "tag" gives a dropdown box with all the selected systems which have data. Choose the one you want.
I was able to have values from each of the systems on the one dashboard.
No guarantees, but this worked for me.
Many thanks for your response. I see the two installations, but no data is loaded from the second installation. I have to see if I got an old version of the transfer script here. When I find a solution I will post it here. Maybe there are more with this problem.

Do you get "N/A" where there should be some data?
I chased this one around and around in my dashboard until I realised that for that particular installation, it had no data or a zero value for that item. I tried a different item where I knew it had some real values for the data and it worked.
In my case, the one that would not display had no PV connected in the system and I was trying to show PV amps and it displayed "N/A".
I selected battery SOC instead, and it displayed the SOC as I had hoped.
Hope that helps.
If it doesn't, then you might have to do what I did, and learn a bit about Docker and Influxdb. I learned enough to be able to use a terminal to look at the database in influxdb and see exactly what was being saved. This was a big help.
If you want to do this, and need some help, I will find the helpful video that explains the necessary commands.
I think my problem is not that I can't find the data in the InfluxDB, but that the data is not transferred to the InfluxDB. The data of the first installation comes without problems.
When I look in the system/Serial table, I only find entries from the first installation. At least here should the second installation be found?
I think my VenusDockerGrafanaServer installation has an error?
Regards
Solved: Each installation can use its own URL. Therefore, the outgoing communication for the MQTTS port 8883 on the domain *.victronenergy.com must be enabled.
