Is the base station (bridge) required to use my dedicated window sensors (e.g. by innogy) or can I use Conrad Connect without them?

Conrad Connect is technically a Cloud-to-Cloud service. Therefore the data of your sensor (e.g. from innogy) has to connect to its manufacturers cloud. In the case of innogy it is necessary to have the bridge station to connect to the manufacturer cloud. Unfortunately by now we have no Door- or Window-Sensor connected that works without a bridge station.
