Make your own API tile for ihost cast

Is it not possible to create a tile where you can use an API yourself? So that it is visible in the cast environment? I would like to make my solar edge visible in the ihost cast environment. I already have the API, but I cannot convert it into a usable tile myself.

eWeLink has an open project on Github, the weather tile, maybe it helps, for your reference:

@vdrijver I am not sure if you look at this already. If you have any updated, please share it here, I would be interested in the results as well.
