SECURITY

Before using this device you have to change the default password for the user 'admin'. This password will be used for the AP mode hotspot, the web interface (where you are now) and the over-the-air updates.

The administrator password is used to access this web interface (user 'admin'), but also to connect to the device when in AP mode or to flash a new firmware over-the-air (OTA).
It must have at least five characters (numbers and letters and any of these special characters: _,.;:~!?@#$%^&*<>\|(){}[]) and at least one lowercase and one uppercase or one number.

GENERAL

General configuration values

This name will identify this device in your network (http://<hostname>.local). For this setting to take effect you should restart the wifi interface clicking the "Reconnect" button.
Delay in milliseconds to detect a double click (from 0 to 1000ms).
The lower this number the faster the device will respond to button clicks but the harder it will be to get a double click. Increase this number if you are having trouble to double click the button. Set this value to 0 to disable double click. You won't be able to set the device in AP mode manually but your device will respond immediately to button clicks.
You will have to reboot the device after updating for this setting to apply.
Remote Control
Home Assistant auto-discovery feature. Enable and save to add the device to your HA console. When using a colour light you might want to disable CSS style so Home Assistant can parse the color.

ADMINISTRATION

Device administration and security settings

The administrator password is used to access this web interface (user 'admin'), but also to connect to the device when in AP mode or to flash a new firmware over-the-air (OTA).
It must have at least five characters (numbers and letters and any of these special characters: _,.;:~!?@#$%^&*<>\|(){}[]) and at least one lowercase and one uppercase or one number.
This is the port for the web interface and API requests. If different than 80 (standard HTTP port) you will have to add it explicitly to your requests: http://myip:myport/
By default, some magnitudes are being preprocessed and filtered to avoid spurious values. If you want to get real-time values (not preprocessed) in the API turn on this setting.
This is the key you will have to pass with every HTTP request to the API, either to get or write values. All API calls must contain the apikey parameter with the value above. To know what APIs are enabled do a call to /apis.
Turn ON to be able to telnet to your device while connected to your home router.
TELNET is always enabled in AP mode.
This name address of the NoFUSS server for automatic remote updates (see https://bitbucket.org/xoseperez/nofuss).

WIFI

You can configure up to 5 different WiFi networks. The device will try to connect in order of signal strength.

General
ESPurna will scan for visible WiFi SSIDs and try to connect to networks defined below in order of signal strength, even if multiple AP share the same SSID. When disabled, ESPurna will try to connect to the networks in the same order they are listed below. Disable this option if you are connecting to a single access point (or router) or to a hidden SSID.
Networks

NTP
