Apple Home vs openHAB

Apple Home is a free app for controlling smart home accessories across Apple devices. Its Home tab groups accessories into categories such as Lights, Security, and Climate and displays their status. It supports compatible accessories for lighting, security, comfort, and entry, along with Matter, cameras, energy monitoring, and voice assistants. The app can show up to four cameras at once, while guest access can grant time-limited permissions for door locks, garage doors, and alarm systems. Accessories can be added by scanning a code or bringing an iPhone or iPad near them; Apple says they cannot be added to Home on Mac. A HomePod, HomePod mini, or Apple TV can serve as a hub for remote access and automation. Examples include turning on lights at a set time, closing blinds when leaving, or adjusting a fan as temperature rises. Siri can also control accessories. Apple says Home data is stored so it cannot read it, accessories are controlled by Apple devices rather than the cloud, and communications are end-to-end encrypted. The app requires Apple devices and compatible accessories.

openHAB is free, open-source home automation software that runs on the user's hardware and can operate without a cloud service. It supports more than 400 technologies and systems, with over 3,000 supported things available through add-ons. Its automation engine includes rules, time and event triggers, scripts, actions, notifications and voice control. Servers can run on Linux, macOS, Windows, Raspberry Pi, Docker and Synology; access is available through web, iOS, Android and other apps. Integrations include Google Assistant, Amazon Alexa and Apple HomeKit. The project says data stays privately at home and that local devices are contacted directly when possible. The myopenhab.org service is free when used with the openHAB Cloud connector. The project describes itself as vendor-neutral and says it avoids lock-in. For Raspberry Pi, openHABian provides an image with preconfigured settings and software. The project has no company behind it; the openHAB Foundation, a registered non-profit organisation, supports openHAB and its development. The community shares examples and tutorials and provides help.
