|
The captive portal component in ESPHome is a fallback mechanism for when connecting to the
|
|
configured :doc:`WiFi <wifi>` fails.
|
|
|
|
After 1 minute of unsuccessful WiFi connection attempts, the ESP will start a WiFi hotspot
|
|
(with the credentials from your configuration)

|
In this web interface, you can manually override the WiFi settings of the device (please note
|
|
this will be overwritten by any subsequent serial upload so make sure to also update your YAML configuration).
|
|
|
|
Additionally, you can upload a new firmware file.
|
|
|
|
When you connect to the fallback network, the web interface should open automatically (see also
|
|
login to network notifications). If that does not work, you can also navigate to http://192.168.4.1/
|
|
manually in your browser.
