UniFi Protect WebSocket events from HC3 – has anyone succeeded?

[ChristianSogaard 73]

Has anyone successfully subscribed to UniFi Protect “true events” (motion / ring / smart detect) directly from Fibaro HC3 using net.WebSocketClient?

What I’ve confirmed so far:

• REST Integration API v1 works from HC3
  GET /proxy/protect/integration/v1/meta/info → 200 OK

• API key is valid (X-API-KEY header)

• Protect version: 6.2.72

What fails consistently on HC3:

• WebSocket subscribe endpoints:

  • wss://<host>/proxy/protect/integration/v1/subscribe/events

  • ws://<host>/proxy/protect/integration/v1/subscribe/events

• Errors:

  • std::runtime_error: error while creating connection

  • std::exception: unable to make cast

Same endpoints + key work fine from curl / Node / Python.

Conclusion so far:

• HC3 WebSocketClient seems unable to handle authenticated WSS (custom headers) required by UniFi Protect.

• I cannot find any confirmed success cases without using an external proxy.

Question:
Has anyone managed to receive UniFi Protect events directly on HC3, or is an external webhook/proxy the only viable solution?

I have setup a webhook in the event in Unifi protect Alarm manager that just sends a http call to start a scene created on the hc3. 
But I guess you already knows about this option
