Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Apple HomeKit
- Requires Apple device for setup and remote access; limited interoperability with non-Apple devices
- HomeKit devices require manufacturer certification, limiting product selection compared to alternatives
- Automations are more limited compared to open platforms like Home Assistant or professional systems
Home Assistant
- Add-ons run only on Home Assistant Operating System installations, and Container installations have no access to them
- Thread and Z-Wave are controlled by add-ons, so a Container install has no out-of-the-box support for either
- A Container installation means bringing your own Linux host with Docker and handling updates by hand
- The recommended install path expects dedicated hardware such as a Raspberry Pi 4 or 5 with at least 2 GB of RAM, an Odroid, or an x86-64 machine
- Every documented hardware option requires a wired Ethernet connection
