Hello again,
here is how to replace *indoor temp* with an additional temp sensor:
Go to *realtimegaugesWC.txt*, look for *intemp* and replace the value with the corresponding tag, e.g *STAT$T1:CURRENT*
Go to *language.min.js*, search for *indoor* etc. and give it the name you want, in my case *Kamera*
Go to *gauges.js*, search for the popup graph you used for *indoor* and replace it with tha one you like.
It is only possible to show the actual temp, no min or max (if I see this correct, Mark?).
