Thanks, Mark.
As I really have no interest whatsoever in displaying inside temp/hum to all and sundry I then thought I could cheat by setting, e.g., “intemp”:%extratemp1%, “inhum”:%extrahum1%, etc., in customclientrawlocal.txt and then renaming the “Inside” radio buttons.
But I notice that there is no "intempTL"or “intempTH” to give max-min on the pop-ups (although “inhumTL” and “inhumTH” are present), and it’s not exactly clear to me from WD’s tagslist what tags I would use anyway!
Back to the drawing board. . .
P.S. No offence, but you have to click twice on a drop down menu to make a selection instead of just once on a button. . .
