Should i create a seperate function for this? And can i rely on connect is just called once, otherwise i might end up with muliple pings being scheduled at the same time.

Should the interval be higher? In this case the function can probably just be scheduled with setInterval

To know if the interval should be higher we really need to test or know when the issue occurs...

My own experience with the bug is that a few minutes are enough to trigger
This should probably be done in https://github.com/home-assistant/home-assistant-js-websocket |
That already got rejected... |

Have you understood the circumstances that let this happen? I have seen it occasionally but not commonly. |
From my understanding the cause for this are bugs in the implementation of web sockets in browers. In the issue if have linked, i was able to reproduce this on an iPad, but people have also reported the same problem on other platforms. So there are probably multiple circumstances that can cause this. |

@bramkragten i can see you assigned the issue to yourself. Are there still some information/context you are missing that i can help with? |

Breaking change
Proposed change
Implement ping from frontend to backend to detect a broken websocket connection that doesn't trigger a disconnect event. Currently there is no mechanism to detect this and the frontend doesn't indicate that the shown values can be trusted.
