Description

This is about local-hosted Node Red ESS.

Suggested Solution

Please try getting dynamic prices maybe every 30min after 12:00. Often they are known eary, at 1230 for example. But then they might only be loaded at 15:00.

Additional Context

I am not sure if my local nodered gets prices from ENTSOe or from VRM. If they come from the victronvrm api, maybe two decreases in refresh interval are needed: VRM getting them from "the market" and nodered getting them from VRM.

[AbelLykens]

For example, today/now, my nodered/dess decided to charge at full capacity, though it's already known that price tomorrow are lower than today. But the system has not yet gotten this data 😉

[AbelLykens]

Again today/now it's charging quite intensely, but tomorrow the prices are lower. It just has not loaded the prices yet..

[dirkjanfaber]

The system already tried retrieving the data each hour of the day, but we increased that frequency from once an hour to 6 times an hour, which should make it respond faster. Node-RED gets the info from VRM, VRM gets it from ENTSOE.

[AbelLykens]

Nice! Both systems (my system + VRM) now try 6x/hr?

[AbelLykens]

Let's see what happens. 12:50 prices are known. Let's hope they appear quickly 🔥

[AbelLykens]

ℹ️ Last update: 3/19/2024, 1:00:49 PM No new prices it seems. Not sure how I can see if VRM has the new prices yet.

[AbelLykens]

we increased that frequency from once an hour to 6 times an hour

That's in some new release in the future maybe @dirkjanfaber ? 😉 . Because prices are known for 30mins now. And 6x/hr = */10.

I am looking at the higher prices tomorrow, see it's the lowest NOW (for the coming days) and am thinking: WHY DON'T YOU CHARGE LIKE CRAZY mr Victron machine 😄 .

[dirkjanfaber]

Just heard that it was only modified for (beta) VRM users, not for Node-RED users. Having that adjusted for Node-RED users too, so it should be better tomorrow. Sorry about that and thanks for keeping a sharp eye on it.

[AbelLykens]

Cheers @dirkjanfaber , appreciated. That means prices are loaded more often on (regular) VRM. And NodeRed would try hourly, or also */10 / 6x/hr? 😉

[dirkjanfaber]

Correct. Both implementation should be in sync tomorrow.

[AbelLykens]

Let's see, 13:00, prices are in.

[AbelLykens]

13:30, no new prices yet

[AbelLykens]

(typing this as I go)

Prices could have been there at 13:10 I guess. But not there at: Last update: 3/20/2024, 1:42:37 PM (T+42min) Last update: 3/20/2024, 1:54:38 PM (T+54min) Last update: 3/20/2024, 2:06:38 PM (T+66min) Last update: 3/20/2024, 2:18:38 PM (T+78min) Last update: 3/20/2024, 2:30:40 PM (T+90min, added later) Last update: 3/20/2024, 2:54:38 PM (T+114min, added later)

Just noticed it updates about every 12 minutes

FYI @dirkjanfaber , it does not seem to load more quickly yet. Will keep my eye on it.

[AbelLykens]

It just appeared (2+ hours later, Last update: 3/20/2024, 3:06:38 PM). Something is not right yet.

[dirkjanfaber]

I am sitting next to the colleague that just deployed a change on this. Tomorrow it should be in earlier, but not before 13:00 yet; that requires a bigger change in the underlying code. This is a quick fix, which already works better than rescheduling at 15:00; the better fix needs some more work.

[AbelLykens]

ACK thanks!

[AbelLykens]

Have my screen open again. Prices are in (13:00). Let's see when it all refreshes on my Node Red 🕺

[AbelLykens]

2:09:47 PM

No luck yet.

[AbelLykens]

Feels like it will refresh at 15:00 again. Not sure it was fixed @dirkjanfaber ... Maybe re-open this issue? 🙂

[dirkjanfaber]

Yes, lets do that.

[AbelLykens]

Fixed!!

[dirkjanfaber]

Ok, prices got just updated and processed in Node-RED (way before 15:00). Closing this issue.
