Tell us what the setup needs to work with

“Not sure yet” is a valid answer. The result will show the decision still needed instead of forcing a guess.

Where will the system be installed?
What Home Assistant foundation will you use?

Starter is built around Home Assistant Green.

Which device radio do you want?

Choose now for exact models, or compare both paths in your result.

Will Green have a power outlet and wired Ethernet?
Can you or a helper install the listed plug-in and battery devices?

Open Home Starter does not include onsite installation.

Will you test notifications with one primary phone?

Notifications can arrive late or not at all. Never treat a quiet phone as proof that everything is fine.

Does this plan require new hardwiring?

Battery devices and plug-in equipment do not count as new hardwiring.

Should the system automatically control water, HVAC, locks, alarms, or other equipment?

Viewing a state or receiving a notification is not automatic control.

No email is required to see your plan. Changing any answer after evaluation clears the old result so it cannot be mistaken for your current plan.
