====== EFR SGM-D4 ====== Der SGM-D4 der EFR GmbH aus Münchgen kann über eine optische Datenschnittstelle IR-Schnittstelle ausgelesen werden.\\ Der Zähler ist als eigenständiges Gerät (moderne Messeinrichtung) einsetzbar. In Kombination mit dem Smart Meter Gateway bildet der SGM-D4 ein intelligentes Messsystem (iMSys). Beim Einsatz im Lastmanagement und bei der EEG-Einspeisung kann eine Steuerbox als zusätzliche Komponente, die über die CLS-Schnittstelle durch das Gateway zur Leitstelle angebunden wird, verwendet werden. ===== Hardware ===== Der Zähler sendet [[software:sml|SML]]-Datenpakete im Sekundentakt. Die Kundenschnittstelle dafür befindet sich rechts neben dem Display und ist mit Metall umgeben, so dass ein Magnet haften bleibt. Man benötigt zum Auslesen den [[hardware:controllers:ir-schreib-lesekopf|IR-Schreib-Lesekopf]].\\ In der Schnittstellenöffnung sitzt die Sendediode rechts. Der verblombte Modulfachdeckel zur Abdeckung und Plombierung von Zusatzgeräten, wie z. B. Smart Meter Gateway (SMGW) oder Steuerbox baut unter der Schnittstelle so sehr auf, dass ein [[hardware:controllers:ir-schreib-lesekopf|IR-Schreib-Lesekopf]] mit nach unten abgehendem USB-Stecker keinen Platz findet. In dem Fall müsste ein kompakter Winkelstecker eingesetzt werden. Außerdem besitzt der Zähler einen Impulsausgang der je nach Stromausführung 5000 oder 10000 Imp./kWh liefert. ===== Schnittstelle ===== Für den Endverbraucher steht eine frontseitige optische Datenschnittstelle zur Verfügung. Die Schnittstellen arbeiten im „PUSH“ Betrieb. Nach PIN-Eingabe mit einer Taschenlampe (das Gerät hat keine Taste), kann „InF On“ für den Betrieb mit vollständigem Datensatz gesetzt werden. Gesendet wird SML-Push nach FNN-Spezifikationen „Basiszähler“ mit einer Datenrate von [[hardware:controllers:ir-schreib-lesekopf#grundlagen|9600 Bd und 8N1]] Zeichenkodierung. Die INFO Schnittstelle liefert nach PIN-Eingabe und Aktivierung von „InF On“ die Werte * Zählerstand Bezug * Zählerstand Lieferung * Leistung gesamt * Leistung L1 * Leistung L2 * Leistung L3 * Spannung U1 * Spannung U2 * Spannung U3 * Stromstärke I1 * Stromstärke I2 * Stromstärke I3 * Phasenwinkel U2:U1 * Phasenwinkel U3:U1 * Phasenwinkel I1:U1 * Phasenwinkel I2:U2 * Phasenwinkel I3:U3 * Netzfrequenz ===== Typenbezeichnungen ===== ^ SGM-D4 ^ ^ ^ ^ ^ ^ | |A| | | | |Klasse A (2 gemäß IEC 62053-21)| | |B| | | | |Klasse B (1 gemäß IEC 62053-21)| | | |6| | | |Direktanschluss 5(60) A -

vor allem, wenn MQTT bereits anderweitig im Einsatz ist. Da vzlogger kein auto discovery bietet, müsste man jeden Sensor umständlich manuell anlegen. Abhilfe schafft hier das mächtige Node-RED Addon. Darin kann man folgenden Flow hinzufügen: Node-RED → „Import“ → einfügen → „Importieren“: [ { "id": "vz_start", "type": "inject", "z": "flow1", "name": "Generate MQTT Discovery", "props": [], "repeat": "", "crontab": "", "once": true, "onceDelay": "3", "topic": "", "x": 200, "y": 140, "wires": [["vz_prepare"]] }, { "id": "vz_prepare", "type": "function", "z": "flow1", "name": "Build Discovery Messages", "func": "", "outputs": 1, "noerr": 0, "initialize": "", "finalize": "", "libs": [], "x": 460, "y": 140, "wires": [["vz_mqtt"]] }, { "id": "vz_mqtt", "type": "mqtt out", "z": "flow1", "name": "MQTT Discovery Out", "topic": "", "qos": "1", "retain": "true", "broker": "mqtt_broker", "x": 770, "y": 140, "wires": [] }, { "id": "mqtt_broker", "type": "mqtt-broker", "name": "HA MQTT", "broker": "localhost", "port": "1883", "clientid": "", "usetls": false, "compatmode": false, "keepalive": "60", "cleansession": true, "birthTopic": "", "birthQos": "0", "birthRetain": "false", "birthPayload": "", "closeTopic": "", "closeQos": "0", "closeRetain": "false", "closePayload": "", "willTopic": "", "willQos": "0", "willRetain": "false", "willPayload": "" } ] Danach sind im Node "MQTT Discovery Out" (→ Eigenschaften → Server-Eigenschaften → Sicherheit) Benuttzername und Passwort für den MQTT-Broker anzugeben. Außerdem muss als Kernstück das folgende Skript (wieder um die eingenen UUIDs ergänzt) in den Node "Build Discovery Messages" (→ Eigenschaften → Funktion) eingefügt werden.
