A Tuesday, on a timeline

The plan builds toward a day like this one.

This family is invented for the example: Priya (runs the household), Dele, Sam (15, they/them) and Mira (8). Each event is tagged with the profile that acted and where.

Morning brief lands in the family group
Weather, each member’s calendar, bin day. Sam: mouthguard, hockey after school. Recycling goes out tonight.

School-run clash caught
Calendar shows Dele’s 08:30 stand-up against Mira’s 08:25 drop-off. Priya, can you take the run? Dele’s stand-up moved to 08:30. Priya 👍 and the brief updates. Nothing is rebooked without a person.

Sam DMs their own agent
add oat milk and those seaweed things goes on the shared grocery list. Sam’s agent has its own memory and no house credentials, and the DM stays private.

16:00
Grocery list consolidated
The week’s group-chat mentions and member adds, deduplicated, sorted by aisle and pushed to the shared Notion page. 23 items. Nothing flagged. Say ‘checkout’ and I’ll load the cart for review.

17:25
House warms up before anyone’s home
Hockey ends at 17:15, so the heating goes to 20 °C and the hallway lights come on at dusk. No message: the group only hears about exceptions.

Mira asks the group for movie night
can we have the film lights and the living-room scene comes on. Third time this month, so the agent offers a one-word skill: Want /movienight?

Day closes, quietly
One line on tomorrow, plus Cart’s loaded for Thursday delivery. Priya to review and pay. Then silence until 07:00.

What Hermes does and what you add

Hermes provides: the gateway with Telegram and WhatsApp group chats, DM pairing, the cron scheduler, profiles, skills and the Home Assistant tools (ha_call_service and others).
You connect: the calendar and Notion, through MCP servers. Hermes has no calendar of its own. The 07:11 clash catch works because the household profile has a calendar MCP server and the cron prompt says to read the calendar first.
You build: the shared grocery list and the “vault” folder it lives in, kept up by a skill. Per-member memory in groups isn’t built in either. See architecture.
Left out on purpose: checkout. The agent can load the cart (metered and fragile, see trap 6), and a person presses pay.

The last prompt shares this sample day with your family so they can pin objections on it. “Don’t message me before 9” is cheaper to learn before everyone’s paired.
