You only have one mode variable per hub, so it cannot have two values at the same time.
Insteadyou have to start making multiple options that cover allthe situations you want.
For example, a lot of people have:
Home-daytime
Away-daytime
Home-Night
Away-Night
Etc
Alternatively, you could probably work something out with Core, but you would have to do it for each rule you set up.
