- What it is
- Google's help page on controlling devices after you add them to the Google Home app. It says how many devices the app can control, how voice commands work through a speaker or display, how automations run several devices at once, and what to check when a device does not respond.
- How much weight it carries
- Google's own help page, read on 2026-10-17 from an archived copy because the live page returned a CAPTCHA to automated requests. Google updates these pages often, and the device count is Google's own figure, so check the live page before you rely on a specific number.
