The ".raw" suffix means you will get the actual value, which could be a
float, or it can be Python 'None'. If you are going to do a comparison, you
must check to see if the value might be None.
Your template code should look something like this:
#if $trend.extraTemp9.raw is None
<td>Unknown</td>
<td>N/A</td>
#elif $trend.extraTemp9.raw < 0
<td class="hes1_trendlo"> ⇩</td>
...
#end if
Same with your air sensor code.
