I am yet another Windy Premium Subscriber who is willing to pay for a Home Assistant Integration. I am actually right now looking into the weather service I am going to subscribe to next, when My yearly Premium Subscription with Windy is expired. I would love to stay with Windy as I LOVE the App, but right now I am paying for an OpenWeatherMap Subscription so that I can use their API in my Home Assistant so that I can use my automations that are triggered based on the weather, and it doesn't make sense to subscribe to 2 Weather Services, when one can do everything I want. I do prefer the Windy App, but the automations are even more important to my daily life.
I really hope you guys wake up to the fact that there is a market out there of paying customers who just want to be able to use your services inside Home Assistant, and start providing that ability.
I do like the product, but will be unsubscribing when my subscription is up, if this ability still isn't offered. Simply because other services, who aren't quite as accurate as you but are good enough, are willing to provide the ability to integrate with Home Assistant, and you are not. I really do hope this changes in the near future. Thank You.
