I am having some issues with the Alpha Vantage component and am wondering if anyone is interested in using/developing a component for the IEX API:
This would not be too difficult for a seasoned developer, since there already are some Python libraries:
I started developing a custom component for my personal use, that eventually could be merged into the upstream Home Assistant code.
I have released an initial version of the component. If you want to test it, please have a go and report any issues or requests.
