I just hooked the EG4 6500ex up 2 days ago. I was excited to see the wifi app, thinking it would have a much better data logger app than the Growatt Shinephone app. but unless I am seriously doing something wrong, it appears that watchpower only does current or one-day logging. I really like the ShinePhone app. Are there any other apps that work with the 6500? Or is there a way to use Shine phone app with EG4?
