If you include home automation:

- Holliday decoration / lights

- Security

- Morning routine (Elliptical on, TV on, Audible book queued up, etc)

- Irrigation

If you don't include home:

- Putting important events like what day the trash should be taken out onto my calendar (taking into account snow delays and holidays)

- My personal tweeting

- Exercise planning / tracking (as much as possible). What is not possible (like recording actual reps) I put as easy to use voice commands on my Alexa

- And I also farm out minor stuff to a virtual personal assistant, which has an API
