Thanks for visiting the Community.
Right now, the only option that is available in household routines are adding actions. Setting any time and delay is limited only on personal routines. No worries, this would be taken as a feedback and in line with this, we’d also like to encourage you to send a feedback regarding this and for any features that you’re looking forward to using with our Google Nest devices.
Let us know if you have additional questions, otherwise we'll be locking this thread within 24 hours.
