This is a app that you configure you weather key and then set it to flash various colors based on different weather alerts and hourly conditions.
I just realized when I made a modification today to improve the purple color with hue lights that i never really posted it here. I think this is because it used Dark Sky Weather for which
I had an API key but was no longer providing them, and I didn't feel like spending the time porting it to Openweather.
Well now I did the conversion since dark sky is going away totally at the end of 2022.
I did not originally write it but ported it from Smartthings a couple of years ago when I first started using Hubitat..
So here it is..
It will blink what ever lights you designate based on motion and weather. The colors for various weather events are user defineable.
here is the app. and it is also available via hubitat package manager
