Forecast using the LED-light on Homey

I would like to create some kind of flow showing the current weather where I want to use the LED ring pending of the state at the weather and also send me some kind of push notice to my phone.

For ex. Between 06 am and 08 am I want to Homey to light blue if it is raining and also send a push notice. It´s raing. Yellow if it is sunny and also send a push notice to my phone. I also want home to check every 15 min if the weather will change

How do a create that kind a flow? I need step by step guid:)
Thank´s
