Steps
For BLE provisioning, add the esp32_improv component to the YAML, which advertises a BLE GATT service implementing the Improv Wi-Fi standard.
For serial provisioning, add the improv_serial component instead, which requires the serial logger to be configured on the device.
Use an Improv-compatible client (e.g. the Improv Wi-Fi web app, or Home Assistant's onboarding flow) to scan for and connect to the device and send Wi-Fi credentials.
Optionally set a next_url (for improv_serial) to redirect the user to a follow-up page after credentials are set.
Use the on_provisioned, on_provisioning, and on_stop automation triggers (esp32_improv) to run device-side logic during the provisioning lifecycle.
Known gotchas
improv_serial requires the device's serial logger to be enabled; if logging is disabled or redirected, Improv over serial won't function.
esp32_improv and improv_serial are separate components for different transports (BLE vs USB/UART) — enabling one doesn't provide the other.
