PowerFSM onEnter calls sendNetworkPing(broadcast), that is sub optimal about firmware HOT 2 CLOSED

I've been taking a quick look into this. Is it best to read the node displayed on the screen, or would it work if the nodedb kept a record of the node that is currently displayed or otherwise to be notified on wake. Maybe even going so far as to be able to set specific nodes that should be notified on wake via bluetooth api.

@BeardyWalrus I think for now either of the first two options would be fine. i.e. either have screen set a "mostRecentViewedNode" property of NodeDB. And when we press the button ping that node.

Or might might be more natural (because buttons and screens have a close relationship), to just ask the screen "what is the currently shown device". I tend to think this option is better.

Thanks for looking at this btw.
