This is not possible beacause of the request-response nature of HTPP.
(The server cannot respond without a question of the client...)
What you can do is sent a "refresh" meta tag that tells the client it should reload the page in x seconds. The newly fetched page could then show the status at that point.
Hope this helps.
Don't get me started about those stupid light bulbs.
