How to find/add SWT (Sensor Input)

[wwwebrat]

Hi! I'm trying to identify which sensor this is: Is it: ID_WEB_SWTin?

Background: If I have enough solar power my "Sunny Home manager 2" triggers this signal to tell the heatpump that it can enable the "pv-mode" (swt on = pv mode on). I would like to make this visible on my HA dashboard.

Can anybody give me a hint? I've already tried to add a custom sensor like described in the documentation:

3.2 Additional sensors (advanced) If you miss a sensor please have a look in the devices under "+n entities not shown". Not all entities can autodetect by the integration. You can enable the entities by your self. The most usefull sensors and parameters are created automaticly. But if you miss a sensor you can add it manually via yaml configuration like the original module from Bouni/luxtronik.

But I get this message

Nicht verwendete YAML-Konfiguration für die luxtronik2-Integration Es ist nicht möglich luxtronik2 sensor durch Hinzufügen von platform: luxtronik2 zur sensor-Konfiguration zu konfigurieren. Weitere Informationen zum Einrichten dieser Integration findest du in der Dokumentation
