Hello how can I create a feature that allows service providers with listings to display their realtime availability by putting a green online status indicator on their listing.

This will show “available now” on their listing when toggle on and should remain on for about 3 hours before automatically toggling off and no longer displaying the available now status unless the user comes back to toggle on again.

Is this possible?

You can use function osc_user_is_online

<?php
  if(osc_user_is_online(osc_item_user_id())) {
    echo 'User is ON'; 
  } else {
    echo 'User is OFF';
  }
?>
