Hi All,

I’m trying to get Weathermap working correctly. I have 2 problems, firstly I don’t see an html or png file created after submitting the map properties and when adding a node in the editor there is not a selection menu to specify the device/interface.

Really appreciate your help and advice.

many thanks in advance
