The red one is for the free API key (see its name).
The green ones are for OneCall API (subscription). You need a location device (current weather). Then you can add further devices for details (daily, hourly…).
If your location device is not working (wrong API key), the detail (child) devices won’t work, too.
Just create a OneCall API key and add a subscription. Add a limit for 1000 calls/day and you have a free API access 
hi, installed OW a couple of days ago and all working great. 2 days ago though, rain prediction and amount stopped working. all other metrics work. if I look in homey at the sensor, all data is updated except for rain prediction and amount. it has data of a couple of days old.
anybody have the same issue? any ideas on what to do to solve it?
thanks!
Thanks Ronny for the great app. It was very helpful in creating a flow that is designed to control my SmartWIngs Zigbee Outdoor Shades based on current weather conditions. Here is my latest YouTube video featuring the advanced Homey flow. Thanks again!
