Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Nest
- Pricing not published in support documentation; individual product prices vary significantly
- All Nest products require Google Home ecosystem integration for full functionality
- Smart home devices operate only within the Google Nest ecosystem; limited third-party interoperability
- Support and product documentation dispersed across Google support rather than centralised Nest site
