thx @emlowe for your feedback
I must admit that I hesitated going forward with this project, but I realised I’m not in to make a perfect Google Home Hub replica. I want to find out how close I can get with the features I want.
The carousel seems similar to what Google does when you ask something. I also looked into the MMM-Page-Selector module because it seems to be a good way to define the different screens. It also seems to be working together with the MMM-Voice-Commands module.
For now I want to make two screens working, one screensaver screen with the Google Photo background, clock and temperature. And one with some information, just to have a proof of concept.
