Ensure you are using one of the available geodjango backends, eg:

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.spatialite',
        'NAME': 'openwisp-controller.db',
    }
}

Add openwisp_utils.staticfiles.DependencyFinder to STATICFILES_FINDERS in your settings.py:

STATICFILES_FINDERS = [
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'openwisp_utils.staticfiles.DependencyFinder',
]

Add openwisp_utils.loaders.DependencyLoader to template loaders and openwisp_utils.admin_theme.context_processor.menu_items to context processors in the TEMPLATES setting of settings.py:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'OPTIONS': {
            'loaders': [
                'django.template.loaders.filesystem.Loader',
                'django.template.loaders.app_directories.Loader',
                'openwisp_utils.loaders.DependencyLoader',
            ],
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',

            ],
        },
    }
]

Add the following settings to settings.py:

FORM_RENDERER = 'django.forms.renderers.TemplatesSetting'

ASGI_APPLICATION = 'openwisp_controller.geo.channels.routing.channel_routing'
CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels.layers.InMemoryChannelLayer'
    },
}

LOGIN_REDIRECT_URL = 'admin:index'
ACCOUNT_LOGOUT_REDIRECT_URL = LOGIN_REDIRECT_URL

urls.py:

from django.conf.urls import include, url
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'', include('openwisp_controller.urls')),
]

urlpatterns += staticfiles_urlpatterns()

Path: openwisp_controller.connection.signals.is_working_changed

Arguments:

• instance: instance of DeviceConnection which got its is_working modified
• is_working: bool variable informing working status of device

This signal is emitted every time DeviceConnection.is_working changes.

It is not triggered when the device is created for the first time.

(
  ('openwisp_controller.connection.connectors.ssh.Ssh', 'SSH'),
)

Available connector classes. Connectors are python classes that specify ways in which OpenWISP can connect to devices in order to launch commands.

(
  ('openwisp_controller.connection.connectors.openwrt.ssh.OpenWrt', 'OpenWRT SSH'),
)

Available update strategies. An update strategy is a subclass of a connector class which defines an update_config method which is in charge of updating the configuratio of the device.

This operation is launched in a background worker when the configuration of a device is changed.

It's possible to write custom update strategies and add them to this setting to make them available in OpenWISP.

{
  'netjsonconfig.OpenWrt': OPENWISP_UPDATE_STRATEGIES[0][0],
}

A dictionary that maps configuration backends to update strategies in order to automatically determine the update strategy of a device connection if the update strategy field is left blank by the user.
