Switch back to default dashboard after some time

Try viewtimeout
You also need card-tools

And my thanks to this post for pointing me to a solution:

Lovelace: Timeout to default_view

I found this repo GitHub - BWilky/viewtimeout: Returns to default view after activity timeout that works like a charm. You can configure in your panel the default view and the time out. Really simple. The only thing is you need to install aswell GitHub - thomasloven/lovelace-card-tools: A collection of tools for other lovelace plugins to use in order to work properly.
