I now have a solution for myself:
if current data is available, it is displayed and if the data is not
current, it is shown how old it is.
With the original code of "sensors.inc" the data is not displayed
immediately when new observations are added.
#if $have_voltage
<tr><th>$gettext("Voltage")</th><th></th></tr>
#for $x in $sensor_voltages
#if $getattr($recent, $x).has_data or $getattr($current, $x).has_data
<tr>
<td class="label">$obs.label[$x]</td>
<td class="data">$getVar('current.' + $x)</td>
#if $getattr($recent, $x).has_data
#set $lasttime = $getattr($recent, $x).lasttime.raw
<td class="timestamp">$get_time_delta($lasttime, $now)</td>
#end if
</tr>
#end if
#end for
#end if
