Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
SmartThings
- Cloud-dependent with no offline operation; requires internet and Samsung servers for all device control
- Cloud communication adds latency compared to local hubs; device response delays up to one second
- Confusing app transition between SmartThings Classic and SmartThings Connect with certain automations only working in one app
- API changes requiring paid subscriptions starting October 2026 break third-party integrations like Home Assistant
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
