Devices become offline

[ATNALDC]

Not sure if it's an issue related to openhab or to Google Assistant / Home. Since few weeks ago openhab devices become offlie if they have not been used for a while (few minutes). I've check trace log and there is nothing.

The strange thing is that if you open google home, it reconnects and works fine, but after a while it start saying that device is offline. It seems as if there was any timeout os the state refresh was not sync.

Let's say that I use myopenhab and nothing has been changed in this time, just some updates of openhab.

Thanks,
