Casting calendar and weater to chromecast

I like to cast my daily calendar and the weather to my TV connected chromcas, and meybe other nice stuff.
I was thinking about casting a url from HABpanel with all the information I like to share.
I seem to have problems casting them to the tv, the url is not accepted I think.
I how of android apps that does the same, I was thinking that tasker could be used to do this start the app. But can I trigger something in tasker with the push a an buttom
Does anybody have experince with this?
I would be greatful for anybody sharing.

Not directly openhab, but maybe you could utilize Dash kiosik to send to the url to your chromecast:
