I am thinking about buying a OpenWB Pro Wallbox. Usually, this wallbox requires an additional OpenWB Standalone or an OpenWB Standard/Standard+ Wallbox as control unit as the Pro is only standalone.

We are already running a SMA Sunny Home Manager to control all of our devices relating to the PV .

Therefore, I would like the SMA SHM to control the OpenWB Pro via API. There is an API available:
https://openwb.de/main/?page_id=771#schnittstelle
According to the OpenWB Hotline no MQTT or other interface that can be used.

Can I address this API via Simple API, and Simple API via Node Red?
