Hi, I am trying to get a higher data rate recorded by my Victron smart solar charger. I am using the mppt along with a raspberry pi3 B (with VenusOS) acting as a CerboGX device. According to the documentation, if in realtime mode, I should get data recorded every 2 seconds in VRM, but I am getting a consistent 1 data per min rate.  
Ive tried using grafana as I thought that would help boost data rate, but not getting consistent results with that. Ill get some amount of data, then nothing all at times.  
Am I missing something? Or is it just not possible to get the data rate I am looking for with VRM? Is there something else I can try to get a faster data rate?  
Thanks, Sylas Wojciechowski

There are two data “channels” from the Cerbo to VRM.

1. The realtime (volatile) data is using a fixed refresh rate of 2 seconds.
2. The database (non-volatile) data is using a refresh rate that is set in Cerbo (Settings - VRM remote portal - Log Interval)

What are you downloading is the second one. Its minimum setting is normally 1 minute.

Hi Alex, thanks for the reply!  
Okay, this is promising. I guess the next question would be, how can I download/view the realtime (volatile) data from VRM?

By _volatile_ I mean that it’s not stored, so you can’t download it… 🙂  
It’s used only for display purposes.

Oh I see. So it sounds like there really isnt a way to get downloadable data in anything over a 1 data/min rate. 😔

You can query the VenusOS device directly via Modbus or MQTT. Or integrate into Home Assistant (which uses the above).

are there any good articles / videos about how to set this up? Will these methods provide a faster data rate? Im looking for somewhere around once every 10 seconds or better.

Hi @SylasWojo,

By far the best way to record per second data from your GX device is with a local Grafana instance.

There is lots more flexibility beyond that as well, see here for where to start, especially the Youtube videos - [GitHub - victronenergy/venus-grafana: Default Grafana dashboards, for docker solution and Venus OS Large](https://github.com/victronenergy/venus-grafana)
