HA Publisher

HA Publisher is a small private utility for a single household. It lets the members of one family trigger their own Home Assistant home-automation actions from an iPhone: opening the Small Gate, the Main Gate, the Main Entrance, and the Parking Entrance (and the lights tied to them). Each action is a single tap on a simple button grid; the app shows a loading state and then a success confirmation. How it works: when you tap an action, the app publishes a small message directly from your device to the household owner's own Google Cloud Pub/Sub topic. The owner's Home Assistant system subscribes to that topic and performs the action at the house. There is no third-party server in between and no public API. Sign-in: the app requires signing in with a Google account that belongs to the household's private Google Workspace organization. This is an Internal Google OAuth configuration and is intentionally limited — only the small set of existing Workspace accounts in that organization can sign in. The app is not designed or intended for the general public. Because of that limited audience, this app is distributed as an Unlisted app: it is not shown in App Store search or charts and is installed by a private link shared only with the household. This is by design. Privacy: the app collects only the email address of the signed-in Google account, and only so the action you trigger can be attributed to you within the household's own system. There is no tracking, no analytics, no advertising, and no data is shared with third parties beyond Google Sign-In and the owner's own Google Cloud Pub/Sub topic, which are required for the app to function. App Review note: a built-in Demo Mode is included so the full interface and flow can be exercised without a Google Workspace account and without any network request.
