Wake up lights -command does not turn lights on. If the lights are on, the command will turn the brightness from 1% to 100%. This is a critical bug, mentioned in many places by many people. Many light pulps require this. This is a software bug in Google Home. Commands "turn light on" and then "wake up the light" does show the correct behaviour but the user can't use this with the sunrise (as it does not turn the light on).
It's not possible to schedule a routine. Many users would like to schedule a routine. Example: "Run morning routine at 8 AM". This alone would fix and solve many issues.
It's not possible to set a routine to run before the alert. For example, a routine to turn lights on or whatever before the alarm sound. This also would fix many other problems.
"Show clock", "show me the clock", "show time" etc do not work but launch google search with the given input. I know I can ask "What time is it" but I just want to see the clock.
This is not the experience we wanted you to have, let me help you. A few things: aside from your Nest Hub 2nd Gen with sleep sensing, which Nest speakers and 3rd party smart devices are we working with? When did your issue begin? Were there any recent changes made? Are your smart devices working on its native app? What app are they linked to?
It would help a lot if you could do a sequential reboot first:
See this guide on routines and how to manage them.
Hope this helps.
