Get latest update of item in sitemap(Netatmo, hue motion, etc)

In my sitemap I would like to display when latest update of a given item was:

Indoor temperature(12.03 28.09.2017) 17C

I have the two items:

Number Netatmo_Indoor_Temperature "Temperature" { channel = "netatmo:NAModule1:home:outside:Temperature" }
DateTime Netatmo_Indoor_LastStatusStore   "LastStatusStore [%1$td.%1$tm.%1$tY %1$tH:%1$tM]"  <text>  { channel = "netatmo:NAMain:home:inside:LastStatusStore" }

So I would like the temperature to be on the right side so it match up with my other items, otherwise I could just have combined them in the rule I assume by creating a virtual item called sitemap_netatmo_indoor_temperature:

 sitemap_netatmo_indoor_temperature.sendCommand( "`Indoor temperature(" + Netatmo_Indoor_LastStatusStore   .state.tostring +")" +Netatmo_Indoor_Temperature .state.tostring +"C")

I’m not sure what you are asking. If you are asking if there is another way besides using a Rule like you’ve shown to put the values from two different Items on one line in the sitemap then the answer is “no”. The only way to do this is to use a rule and a virtual Item (String Item).
