Receive instant push notifications on your phone and voice announcements on your Google Home every time someone orders — with cumulative BAC tracking per person. Powered by n8n, ntfy.sh, Home Assistant, and n8n DataTable.

Overview

This template extends template 5 — Menu Order Push Notifications with a Home Assistant TTS voice announcement triggered on every new order.

When a customer submits an order:

1. The website sends a POST request to an n8n webhook
2. n8n forwards the order to ntfy → push notification on your phone
3. n8n logs the order to the DataTable, reads all orders for that person today, and calculates the cumulative BAC (Widmark formula)
4. n8n calls a Home Assistant script → voice announcement on Google Home

No cloud TTS fees. No external services beyond HA + Google Home. Fully self-hosted.
