How to prevent game pause when head set idle

I’m using a vive pro wireless. When the headset goes into idle mode (take headset of during game play) the game pauses/stops rendering (headset screen off, monitor game freeze). Keyboard events not functional until headset leaves idle mode.

I can see that because the vive controllers are not moving any more and worse, if I’m the host all my clients get disconnected.

It works with the cable solution and might be a SteamVR issue but they directed me to HTC and I’m in contact with them now. Regardless their solution or bug, I don’t want my game to pause or kick clients because of some SteamVR issues.

How can I make my implementation smart enough to deal with that?

Thanks
