Plugin: PV Forecast / Ertragsprognose für eure PV-Anlage

[hismastersvoice]

Kann ich auch bestätigen.
Wobei es egal ist, 10 reichen genau so, so genau ist kein Forecast dad man diesen fast stündlich aktualisierten müsste.

I looked the first time a bit deeper to your solution.
I'm not sure but it looked for me that there is no consideration of time shift and daylight saving time. Solcast use UTC so, so for me in Germany there is a 2 hour difference in summertime to UTC.

I'm wondering also that you use all 48 values, if í sum all 48 values the forecast ist much to high. I only use 24 full hour values to sum, than I get a perfect forecast.

Reference the post at -

https://www.loxforum.com/forum/projektforen/loxberry/plugins/119128-plugin-pv-forecast-ertragsprognose-f%C3%BCr-eure-pv-anlage?p=179933#post179933

That's correct, there is no consideration of time shift and daylight saving time. But I don't use the timestamps on any values. Each time Solcast is polled, 'Period 1' is the next 30 minutes from when the poll occurred; 'Period 2' is 30-60 minutes from polling event, etc.

So the 48 values summed (each a 30 minute production value) provides a rolling 24 hour look ahead.

A single captured value for the forecast day is triggered at 9pm of the preceding day. I could make this trigger later (closer to sunrise), but the risk becomes that the 24 hour rolling window captures some sunrise of the 2nd day forward. I'm also still awake at 9pm and can see what the next day has in store.

Solcast is providing very high update rates in their solar forecasting; every 10 minutes in Australia and 15 minutes in Europe -

https://solcast.com/solar-data-api/rapid-update/

I would like to get better accuracy for a charging control system of a solar battery I have. By polling more often when I need the data (ie. daylight hours), I can better utilise the 20 poll limit.


A Python client library exists for returning the forecasts via script -

https://github.com/cjtapper/solcast-py

I've installed this on the Loxberry, but have had no success making it work. I also lack any meaningful Linux skills...

I would be very grateful if anyone can give the API a try and provide guidance.

I have build a shell scripts that works with the json data that you can download.
the first poll for me is at 4am local time.
And after that every hour until 10pm so I'm always into the 20 poll limit an get an update during the full day. That fits for the longest days in summer.

I'm also calculate the time shift between UTC and local time and put that into the calculation. So the values of the hours fits better than without use time shift. In Germany we have with daylight saving time 2 hours difference.

My battery had her own forecast and I don't need to control.
I use it to of schedule the production of warm water, the dish washer, washing machine etc

Solcast works better for me that the old provider in my plugin.

I would be very interested in your shell script. Is it possible to download from somewhere?

[hismastersvoice]

1. Create a folder solcast in /opt
2. Create a file sc_calc.sh in the folder /opt/solcast
3. Copy the code below into the file, setup the paramters and save
3. sudo chmod 0755 /opt/solcast/sc_calc.sh
4. copy the the lines from the second codeblock blow the existing lines into /etc/crontab "at the end of the file the last line hast to be a empty one"
5. sudo service cron restart

The results get send via UDP to the MiniServer.
So you have to create Virtual UDP Input with the used Port eg. 7000
Also Virtual UDP Input Command with command recognition e.g. sc_total.today_w=\v

sc_calc.sh

Thankyou! The script works fine. I haven't got some values yet, but it's night-time here. I should see them roll in tomorrow.

[Tico]

I'm having a small problem getting crontab to automate the process. I'm currently manually injecting the command -

bash sc_calc.sh

The crontab looks as pictured below. I've checked the permissions on crontab which are 0755. Is there anything obviously wrong?

Also a question - Is the sum of daily values local midnight to local midnight? I'm UTC+8, so might I be seeing 0800 local to 0800 local?

day_1_string_0=$(echo $date_1"T00:00:00.0000000Z");

[Tico]

Thanks. I did alter the FILE called crontab in /etc. That didn't work. I had success with creating a crontab in -

/opt/loxberry/system/cron/cron.d

following the guide here -

https://www.loxwiki.eu/display/LOXBERRY/Create+own+cronjob+on+LoxBerry

The only issue I had was ongoing emails with error - "TERM environment variable not set." - That was resolved by putting MAILTO="" in the crontab.

Maybe the "TERM environment variable not set" has something to do with why it wasn't working in /etc?

[stoeff99]

By adding "/bin/bash" to the crontab, I could get the script executing via the crontab. See below:

I discovered a curious aspect of Virtual Inputs when using the Solcast http URL.

I'm using two different accounts with two separate API keys for different data streams.

1. The Loxberry script and UDP inputs for the Production Forecast (API1) and,
2. Loxone Virtual HTTP Inputs for the retrieval of the Radiation Forecast (API2).

API2 is being polled every 4500 seconds (1hr 15mins). This keeps it within the daily limit of 20 calls.

This works fine until I do any modifications to the Config and use 'Save in Miniserver'. Once this occurs, I notice that I hit the polling limit for API2. The more times I execute 'Save in Miniserver', the earlier in the day I hit the polling limit.

My previous assumption was that Virtual Inputs were not initially polled until after the elapsed time of the polling cycle. ie. 4500 seconds after 'Save in Miniserver'. I expected I should use less polls whenever work is done on the Config, with the first and subsequent polls pushed back by the applicable working time before saving.

My new hypothesis is that the Virtual HTTP Input is polled immediately upon 'Save in Miniserver', just the Command Recognition doesn't work in the immediate timeframe of the reboot. This hypothesis seems to match what I'm observing.

This could be confirmed if someone has a Virtual HTTP Input where the polling address 'does something', rather than being used for Command Recognition.

Curious if anyone can shed some light?

[hismastersvoice]

I think the poll is after every restart, and that makes sense to have after a restart the actually values.

I belove that is a thing you can't change.

Hi.
Wollte dein Plugin testen, jedoch hab ich ein Problem.
Meine 10kWp Anlage ist auf dem Haudach und auf der Garage verteilt. Jeder Teil zeigt in eine andere Himmelsrichtung.
Leider kann ich in deinem Plugin nur -90 bis +90 eingeben.
Ein Teil meiner Anlage zeigt jedoch nach NordOst was ja -135 sein müsste. Dies geht in deinem Plugin leider nicht.
Wenn ich jedoch im API Aufruf -135 eintrage klappt das einwandfrei.
Kannst du das im Plugin fixen?
Danke

Schau auf den Status in Post 1, anbei auch der Screenshot aus LoxWiki.

Ich werde an dem Plugin nicht mehr arbeiten und es auch nicht fixen da ich selber nicht mehr installiert habe und auch nicht nutze.
Der Forecast ist einfach zu schlecht, deswegen bin ich auf Solcast gewechselt.

[hismastersvoice]

Du hast als no comercial erst mal 1000 frei, erst wenn die 1000 verbraucht sind geht es los mit den 20. Oder habe die das geändert?

API Usage
Usage Allowance / 520 of 1000 calls remaining
Daily Usage Limit / 20 calls
Daily usage does not apply until the usage allowance is consumed or expires on the 2019-11-16

[hismastersvoice]

Die Werte sind extrem viel besser bei mir, nur so zB
01.11 ~500W Abweichung
31.10 ~350W Abweichung
30.10 ~700W Abweichung

Sicher gibt es auch mal Ausreißer mit 1-2 kW daneben, aber das ist sehr selten.
Bei pv-forecast waren mehrere kW Abweichung die Regel.

[AlexAn]

OK dann geht´s gleich weiter

Verfolge gerade einen anderen Ansatz bei Solcast.
Schick mir den Json Link per NodeRed nach MQTT und mach dort Expand Json data auf einen virtuellen Http Eingang mit 96 Werten in die Zukunft. (30Minuten Takt)
Json Link: https://api.solcast.com.au/world_pv_...i_key=xxxxxxxx



Anbei der Vergleich der 2 Systeme


hismastersvoice machst du im Script die Berechnung der Tagesprognose 1mal am Tag?

hismastersvoice machst du im Script die Berechnung der Tagesprognose 1mal am Tag?

Verstehe ich nicht...
Außer das du die Werte je Stunde hast und dafür NodeRed und MTTQ brauchst.
Wenn du die Werte je Stunde willst ist das eine Zeile im Skript zu erweitern.
Ich sehe auch nicht wie du die Zeitverschiebung zwischen UTC und unserer/deiner Zeitzone in die Berechnung mit untergebracht hast?

[hismastersvoice]

PS: Die halbstündlichen Werte darfst du nicht einzeln aufsummieren, nur die stündlichen. Anderenfalls bekommst du eine Forecast der ~ doppelt so hoch ist wie er sein sollte.

[AlexAn]

Das Ding gibt alles so aus wie es ist also müsste ich mit den Wert 0 für Ende der aktuellen 30min Periode beginnen
Mal schauen ob ich die Berechnung mit einem Statusbaustein mache

[hismastersvoice]

Ich habe zu beginn auch den Fehler gemacht alles zu addieren.
Bin dann aber schnell drauf gekommen das die Werte immer recht genau doppelt so hoch waren wie die Realität.
Deswegen werte ich nur die vollen Stunden aus, das passt sehr gut.

Die Frage zur Zeitzone würde mich noch interessieren.

[hismastersvoice]

hismastersvoice machst du im Script die Berechnung der Tagesprognose 1mal am Tag?

Nein, Je Skriptdurchlauf.
Mich interessiert ja nicht was heute morgen die Prognose war, sondern die noch folgende Leistung. So ist jede Stunde der Wert geringer.

Was ich aber mache, ich speichere den Prognose Wert morgens um 5 in einen Analogspeichher. Das nutze ich aber nur um zu sehen wie gut die Vorhersage war.
Das ist natürlich nur die halbe Wahrheit, da die Brechungen sich im Tagesverlauf ja noch ändern können.
Zu Testzwecken habe ich mir die json-Datein alle mit Timestamp über mehrer Wochen gespeichert um die Werte zu analysieren.
So bin ich darauf gekommen das die Progonse extrem genau ist.
Auch zB das morgens der Wetr zB für 14 Uhr zB 1,344 kW war und und beim Abruf um 13 Uhr 1,127kW. Wenn ich das nun mit der realen Leistung um 14 Uhr vergleiche (1,14) bin ich sch recht zufrieden das immer wieder neu kalkuliert wird.

Ich nutze die Stunden Leistungen nicht, nur die next 3 oder next 6, so kann ich am besten vorhersehen ob Tockner etc laufen sollen.
Je Stunde ist hier zwar für den Start des Trockners genauer, wenn aber nach einer die Stunde die Leistung einbricht bringt das nix.
Deswegen versuche das ganze etwas aufzuweiten.

[StoRmtec]

Hallo
Da ich auch gerade das mit dem Nodered versuche, habe ich eine Frage. Und zwar wie machst du das das d next 3 oder next 6 herausbekommst. Zählst du einfach die zusammen? Wie bekomme ich den Wert zu einem HTTP Virtuellen Eingang. Wenn ich einen Texteingang nehme bekomme ich einen Wert sonst nicht.
Danke
