Try this

<column>
<name>Foobar</name>
<content>
  <attribute>0x0</attribute>
  <expression>value().toString() + “ &#176;C”</expression>
</content>
</column>

The docs have a nice example for this, too.

Regards,
Jan

Betreff: [spectrum] Custom IconLabel

Hi.
I have modelled a new tempsensor in Spectrum, now I want to display the 
currrent temp value on the iconlabel, so far so good.
I have managed to display the temperature value, now I want to add ºC behind 
the actual value.
Look at the xml below, in this case i get only ºC on the icon label, how do I 
get "OneClick" to show both the attribute value and the message?

Best Regards
