This update enhances the stability of our IoT Box integration by splitting websocket messages. Previously, messages targeted multiple IoT devices simultaneously, which could cause issues. Now, each message is sent individually, per device, ensuring smoother and more reliable communication.

In order to ensure ws compatibility with stable IoT Boxes versions, we now split websocket messages to send one per IoT identifier, instead of one targeting multiple ones.
