  while true do
    table = @brewer.status_table

    before_temp = @brewer.pv
    @brewer.wait(to_seconds(delay))
    diff = @brewer.pv - before_temp

    clear_screen
    puts table

    ping([
      "Current Temperature: #{@brewer.pid['pv_temp']} F",
      "Set Value Temperature: #{@brewer.pid['sv_temp']} F",
      "Current temperature has climed #{diff} F since #{delay} minute(s) ago",
