Looking for ideas: Installing a button to toggle between two websites

[DCBene]

Hey everyone,
I've been using chilipie to display the output of a weather station of mine for years now. And it works really well. Now, I'd like to add the output of a second station. Ideally, I'd like to toggle between the two through the push of a button. Has anyone done this before? Or would anyone have some insight on how this could be done?
Thank you so much!
