The harmony hub integration hangs when switching activities too fast

[nldroid]

The problem

When i switch fast (mutiple times in a couple of seconds) between Harmony hub activities via Home Assistant, the integration stops responding and i can't use the buttons anymore.

When i do it slowly, all goes well.

When it hangs, the only thing i can do is to reload the extension.

When i use the remote when the integration hangs, the (current activity) status is updated but the buttons still don't seem to work.

My harmony hub is on a dedicated 2.4 Ghz network. When the integration hangs, i can still ping it.

The hubs don't accept commands once a activity execution in progress. You have to wait for it to finish changing state before you can send new commands.

The problem is that it never seems to end. Even after days, the buttons in HA won't work anymore. Switching activities with the remote still works.
