Quick answer
Start with a single useful routine and expand only after confirming local behaviour and a recovery path. A broad device shopping list is not an installation plan.

| Product | Research use case | Sourced features | Decision limit |
|---|---|---|---|
| Home Assistant Green | First routine | Software: Home Assistant preinstalled; Control: Runs locally; Zigbee: Additional adapter required | Choose one trigger and one useful action, then test the physical controls before adding more devices. |
What to check before buying
| Decision factor | What to establish |
|---|---|
| First routine | Choose one trigger and one useful action, then test the physical controls before adding more devices. |
| Radio choice | Buy the adapter and devices for the selected integration instead of mixing incompatible radio variants. |
| Offline behaviour | Identify cloud-dependent steps and test how the routine behaves when connectivity fails. |
| Maintenance | Document credentials, backups and recovery so another household member can operate the home. |
Home Assistant Green
Why it belongs here: For first routine, the Official hardware documentation record documents Software: Home Assistant preinstalled; Control: Runs locally; Zigbee: Additional adapter required.
Who should consider it: Buyers assessing first routine who can meet the documented Home Assistant Green installation and operating requirements.
Before choosing: Choose one trigger and one useful action, then test the physical controls before adding more devices.
Evidence limit: Home Assistant Green is assessed for first routine using manufacturer documentation; this does not establish a comparative reliability test result.
Full sourced specification recordHow we chose
Selection centres on first routine, radio choice, offline behaviour, maintenance. Start with a single useful routine and expand only after confirming local behaviour and a recovery path. A broad device shopping list is not an installation plan. This is source-based research, not a hands-on test or star-rated ranking.
Read the complete methodologyCommon questions
Should I replace every switch first?
No. Validate one routine and retain usable physical controls before scaling the installation.
Can every automation work without internet?
No. Local execution depends on the devices and integrations involved; a local controller does not make cloud-only services local.
