My forecast data from the VRM dashboard (under Installation data > Overview) currently appears to be implausible, showing roughly double the correct figures, for both Solar production and Consumption. [2025-08-06 01.51.58 vrm.victronenergy.com 15e1c0342361] The data displayed in the graphs reflec…

Hi Snaj, That’s pretty similar to what I’m doing with it… I plot it all in Grafana alongside the ‘actual’ generation data for comparison in order to gauge relative accuracy. The VRM data has (prior to this hiccup) tended to be the most accurate. I usually just make a single call at our grid rate…

Update for August, 11: Now also D0 forecast is complete rubbish and only at around 50% of the expected yield, d1 same=same. [image] The weather is still supreme and I’m expecting for today and tomorrow yields around 55 kWh, just as in the last days. Now with even d0 unusable my Energy Management…

@jarco also here my PV forecast values are about half the expected values

don’t forget API please, it is still not working thanks Stan

Hi all, Sorry for the continued issues. We’re working hard to resolve this. In short, the underlying database is having a lot of performance issues. Our top priority is making sure that all incoming data is reliably stored. This means that, at times, we’ve had to temporarily disable VRM features …

Looks like the performance issues persist. Well, as long as the data are safe, I won’t complain. Fingers crossed you catch all the bugs and gremlins soon, but don’t forget to get some sleep either. Tired engineers and sophisticated systems don’t match! Luckily, I don’t need the VRM to control my sy…

Hi Jarco, Please don’t forget about the API, it is now completely stopped… (reading returns time out error) Stan

This is still down to the ongoing DB performance issues. Sorry for the inconvenience, the team are working hard to resolve.

VRM lots of malfunctioning
