IDM ALM Navigator 2 // IDM Template zur gezielten Befüllung des Speichers mit Wärme aus PV Überschuß funktioniert nicht

[FSTNDonald]

Describe the bug

In EVCC 0.209.1 (GUI) habe ich eine IDM WP erzeugt und als Temperatur "Warmwasser Oben" ausgewählt. Im GUI wir die IDM angezeigt ebenso wie die oberer Trinkwassertemperatur, z.B. 55 Grad.

Ziel ist es, sobald PV Überschuss besteht, die Speichertemperatur bewusst zu erhöhen, z.B. auf 60 Grad, d.h. also den PV Überschuss in einen Wärmevorrat im Speicher zu wandeln.
Dazu müsste EVCC das Modbus Register 1710 auf "1" stellen, sobald PV Überschuß vorhanden ist. Zum Testen habe ich "Min+PV" bzw. "Schnell" ausgewählt -> 1710 bleibt immer auf "0".
Sobald das eingestellte Temperaturlimit überschritten wird, müsste dann 1710 zurück auf "0" geschrieben werden, d.h. Heizen beenden.
Gegebenfalls kann sogar die Höhe des Überschuss mittels Register 74 mitgegeben werden.

Das funktioniert leider nicht, laut IDM Modbus-Monitor wird nur Register 74 (Überschuss) im o.a. Fall "Heizen" mit GLT=5.5 beschrieben. Sobald Heizen beendet wird (z.B. durch Reduktion der Zieltemperatur in EVCC), wird 74 mit GLT=0.0 beschrieben.

Steps to reproduce

1. im EVCC GUI eine IDM WP erzeugen
2. als zu überwachende Temperatur "Warmwasser Oben" auswählen
3. die IDM für Modbus-TCP konfigurieren in der GLT und per GLT-Monitor die MODBUS Register 74 und 1710 überwachen
4. zum Test mittels "Schnell" den Heizbetrieb bis zur Erreichen des im EVCC GUI eingestellten Temperaturlimits aktivieren
5. Ergebnis der Aktivierung im GLT-Monitor der IDM überwachen

PS: im Config unten ist db:4 von einem vorherigen Versuch mit der Speicher-Temperatur (Buffer) anstelle Warmwasser-Oben.

What type of operating system or environment does evcc run on?

Linux

External automation

• I have made sure that no external automation like HomeAssistant or Node-RED is active or accessing any of the mentioned devices when this issue occurs.

Nightly build

• I have verified that the issue is reproducible with the latest nightly build

Version

209.1

Update:
EVCC schreibt in der Tat nur alleinig den PV Überschuss in 74, abhängig davon, ob das Temperaturlimit des verwendeten Sensors erreicht ist oder nicht -> damit (versteckt) Steuerung, ob PV Überschuss verwendet werden soll oder nicht für die Wärmeladung des Speichers.

In der IDM ist dann die Konfiguration für PV anzulegen (Fachmann-Ebene) - dort sind die gewünschten Temperaturüberhöhungen separat konfigurierbar zu Verwendung des PV Überschuss.

@Entwickler - bitte irgendwo dokumentieren, wie das IDM Template funktioniert und was an der IDM konfiguriert werden muss, damit es funktioniert.

Insofern Ziel erreicht, aber nicht EVCC logisch direkt via WP SOC (=Zieltemperatur), sondern über Bande.
Unter dem Strich logisch, aber etwas Hilfestellung, d.h. Hinweis über notwendige Konfigurationsänderungen der IDM wären hilfreich.

Kannst du auch selber im Template als Info (requirements) eintragen.
https://github.com/evcc-io/evcc/blob/master/templates/definition/charger/idm.yaml

requirements:

Update2:
Leider mit Zitronen gehandelt - die IDM verwendet die unter PV eingetragenen Temperaturüberhöhungen auch ohne PV Überschuss (74 = 0.0).
Die IDM beherrscht die Protokolle diverser Hersteller für PV Integrationen, verwednet habe ich "Gebäudeleittechnik/Smartfox". Vermutlich werden nicht die notwendigen Register bespielt, z.B. scheinen diese explizit für GLT vorgesehen zu sein (GLT-Monitor):

, die stehen alle auf "-1".

Mein Ziel ist weiterhin, mit PV-Überschuß den Speicher (Kombi, WW + Heizung, je ca. 500 l) zu überladen, so dass die WP während der anderen Zeiten seltener (mit den Standard-Temperaturen) in Betrieb geht.

Update 3:
es zeichnet sich eine Konfiguration der IDM ab, die den gewünschten Zweck erfüllen würde (das wird getestet über ein paar Nacht / Tag Wechsel).

Zurück zu den Fehlern des IDM Template:

1. es ist zappenduster draussen
2. aut EVCC GUI läuft das Haus auf Akku der PV mit ca. 820 W plus etwas Netz
3. laut GLT der IDM meldet EVCC dennoch einen Solarüberschuss von 1.4 kW

how come ?

[FSTNDonald]

Problem soweit eingekreist - EVCC meldet an die IDM einen falschen Wert für PV Überschuss.

Das Problem ist ähnlich der komplexen Logik bei der Steuerung des Vorrangs zwischen BEV oder PV Akku? Gelöst ist das über die unterschiedlichen Prioritäten anhand des PV Akku Ladestandes für dieses Szenario.

Mein Vorschlag für WP ist, als PV Überschuss ausschliesslich die Leistung an die IDM zu melden, die ansonsten für Einspeisung verwendet werden würde. Eine WP zieht sowieso mehr als eine normale PV leisten kann und hat für mich deswegen die geringste Priorität.
Im HA Forum ist zu lesen, dass die IDM die Werte gerne zyklisch hätte. Frage an EVCC - mit welcher Frequenz wird PV Überschuss an die IDM gesendet - nur bei Änderung oder regelmäßig im 5 Minuten Intervall ?
