Nordnet for Home Assistant

The nordnet component is a Home Assistant custom component for fetching your Nordnet holdings (investments) from their API and expose them as sensors.

Installation

Manual Installation

1. Copy nordnet folder into your custom_components folder in your hass configuration directory.
2. Restart Home Assistant.
3. Configure Nordnet through Configuration -> Integrations -> Add Integration.

Installation with HACS (Home Assistant Community Store)

1. Ensure that HACS is installed.
2. Search for and install the nordnet integration through HACS.
3. Restart Home Assistant.
4. Configure Nordnet through Configuration -> Integrations -> Add Integration.

Configuration

Username & Password

Pretty straight forward, the credentials used to login to your Nordnet account.

Sadly Nordnet do not have a API token system or similar for private customers (unless you pay them BIG $$$!), so the only way to have the integration work, is by supplying username and password when logging in.

Account ID

You can find your Account ID by going to https://www.nordnet.dk/oversigt/konto and

1. Use the number next to your account name in on the left'ish hand side of the screen under their logo
2. Use the the number at the end of the URL (e.g. https://www.nordnet.dk/oversigt/konto/1 will be Account ID value 1)

Trading times

To avoid requesting data from the Nordnet API when the stock markets are closed (assuming mainly EU and US stock exchanges), you can set the Start trading time and End trading time to the hours where there would be changes in the underlying stocks.

Outside the configured trading hours, the integration will have a ~10% probablity (rather than 100%) of making a requst for new data from Nordnet API to refresh data, mainly to keep the login session alive and catch some after market changes.

The Start trading time and End trading time uses the Time Zone configured in Home Assistant

Query Nordnet API interval

How often the integration should refresh its data from the Nordnet API.

State and attributes

A sensor for holding will be created with the state being the the total market value of the holding in DKK

• sensor.stock_price_for_alefarm_brewing_a_s_alefrm
• sensor.stock_price_for_advanced_micro_devices_amd
• sensor.stock_price_for_{name}_{ticker}

Debugging

The intergration have pretty verbose debug logs, so if something is not working as expected, I would recommend moving to debug log level in configuration.yaml

logger:
  default: warning
  logs:
    custom_components.nordnet: debug
