I would like to get basic weather based on Lat Long (not my current location). Any ideas of how to accomplish this?
I think that you don't have this option in Kustom apps, what you can make is choose a location that you want in the Alternate locations in the settings of your Kustom app, and then put an Overlap group and in the Layer you can choose a location of the alternates, the information in this Overlap are going to be the information of this location.
Bit of a longshot, but you could try putting the co-ords into a gv. I've something similar with a map component I made; my current lat/long are in a gv, if I want a map of somewhere else, I get the co-ords for that place and put them in the gv.
Maybe worth a shot 🙂
