Viessmann Access vs Home Integrator Core

Viessmann Access app - The secured and simple solution for passwordless authentication to Viessmann web applications. Viessmann Access is the app for strong authentication to Viessmann web applications without entering a password or second factor. After setting up and registering your account, you receive a push notification when you log in, which is released by you using your secure PIN or, depending on the device, biometric security features such as facial recognition or fingerprint. And you are already logged in.

Home Integrator Core is a fast, privacy-focused controller for Home Assistant — built for people who just want to tap and go. Build a clean tile grid of only the devices you care about. One tap to toggle lights, switches, locks, and scenes. Sensor tiles show live values for temperature, humidity, and more. Stream your cameras directly in the dashboard. Group devices into folders by room or zone. Reorder everything with drag and drop. Set a PIN to lock the app from accidental changes. Control your home hands-free with Siri and Shortcuts — toggle devices or check their status by voice, even when the app is in the background. Try it before you connect — Demo Mode lets you explore the full interface with mock devices, no Home Assistant instance needed. Works with any Home Assistant setup including Nabu Casa. All data stays on your device.
