Dear all, Happy to inform you of the following changes to stable VRM: We now show the admins of an installation group on the installation group’s page, to make it more clear who has editing rights to the group [Screenshot 2025-03-27 at 08.56.16] Forecasts are now shown as a range, to reflect …

[image] Barbara Jansink (Victron Energy): Forecasts are now shown as a range, to reflect better that they come with a margin of error Hi Barbara, VRM shows solar forecast 13 - 16 kWh: [Screenshot_20250327_141533_VRM] But VRM-API in Node-RED still shows almost 22 kWh from start of today ti…

What I can imagine is that the solar yield forecast total for the day from NodeRED is static, where the VRM range updates. So if you look at both in the early morning, I expect them to match, but let’s say that from 8 AM to noon there is fewer sun than expected in the early morning, VRM adjusts, bu…

I think I’ve already seen that the Node-RED value also changes during the day, but I’ll look at this again in detail. Of course, it would be ideal if Node-RED would also adjust this every hour, for example. Otherwise the Node-RED value would be pretty useless. Who would be the contact person in thi…

I suppose that Node Red gets data from VRM API and should also change during day. But in VRM API there is still one field “solar_yield_forecast”. Is this also going to change into two (additional) fields min/max?

I think I was able to solve the puzzle: In VRM, the sum of the actual PV yield of the past hours and the current hour + the predicted PV yield of the following hours is displayed. What was forecast in the previous hours is not included in the displayed range. That’s OK. In NODE-Red (VRM-API), on t…

That’s OK for me, because: VRM-API in NODE-Red is very well adjusted several times during the day. But only the hourly values that are still in the future. On the other hand, those for past hours remain unchanged in NODE-Red, even if they differ greatly from the actual yields achieved. This is fin…

Hi I’m not sure if this is related to yesterday release, but my Octopus Agile Prices for tomorrow 29/3/25 have not loaded into DESS. I’ve tried turning DESS on and off and have also changed and updated the API key from Octopus. Any one else having the same issue or got a resolution? dess octopus

@Barbara The consumption forecast, or rather the predicted SoC value of the battery, hasn’t been adjusting as usual since your last update. Is this intentional? [Screenshot_20250329_064214_VRM]

Yes. Same here in Latvia, Nordpool prices not loaded. And today it I’d not charge batteries according to schedule.
