As mentioned above, I changed from Inside temp/hum to Garden temp/hum.
First I edited customclientrawlocal.txt so that all 10 of Mark’s “in”-variables (“intemp”, “inhum”, etc.) pointed to the WD tags for the extra sensor data (like your %extratemp1%, %extrahum1%, etc.) instead of inside data.
Then I edited language.min.js and changed every “Inside” label under LANG.EN to “Garden”: to, e.g., temp_title_in:“Garden Temp” instead of temp_title_in:“Inside Temp”.
That changed the radio buttons, gauge labels and the pop-up max-min info from Inside to Garden. See http://swanston.maui.co.uk/gauges.htm.
Hope that’s some help.
