# Dynamic DNS Update for Home Assistant

This project is a Flask application that updates the dynamic DNS records for a list of hostnames with Loopia as the DNS provider. It also includes a Home Assistant sensor and automation.

## Installation

1. Clone the repository:

    ```bash

    git clone https://github.com/swetoast/smartresolver.git

    ```

2. Navigate to the project directory:

    ```bash

    cd smartresolver

    ```

3. Install the required Python packages:

    ```bash

    pip install flask requests configparser

    ```

## Configuration

1. Open `dns_endpoint.conf` in a text editor.

2. Under the `[Credentials]` section, set `username` and `password` to your Loopia DNS credentials.

3. Under the `[Hostnames]` section, set `hostnames` to a comma-separated list of hostnames to update.

4. Under the `[DEFAULT]` section, set `HOST`, `PORT`, `USE_HTTPS`, `CERTIFICATE_PATH`, and `KEY_PATH` as needed.

## Running the Application

1. Start the application:

    ```bash

    python smartresolver.py

    ```

2. The application will now update your dynamic DNS records whenever you access `http://IP_ADDRESS:PORT/update_dyndns`.

## Home Assistant Sensor

To add a sensor in Home Assistant that triggers the dynamic DNS update:

1. Add the following to your `configuration.yaml`:

    ```yaml

    sensor:

      - platform: rest

        resource: http://IP_ADDRESS:PORT/update_dyndns

        name: DNS Resolver

        value_template: '{{ value_json[0].status }}'

        json_attributes:

          - 'hostname'

          - 'ip_address'

        scan_interval:

          hours: 4

    ```

2. Restart Home Assistant to apply the changes.

## Home Assistant Automation

To add an automation in Home Assistant that triggers the dynamic DNS update when the IP address does not match:

1. Add the following to your `automations.yaml`:

    ```yaml

    alias: "Auto-Update: Update DNS Resolver on IP Mismatch"

    description: >-

      This automation updates the DNS Resolver sensor when its IP address does not

      match with the external IP sensor.

    trigger:

      - platform: template

        value_template: >-

          {{ states('sensor.external_ip') != state_attr('sensor.dns_resolver',

          'ip_address') }}

    action:

      - service: homeassistant.update_entity

        target:

          entity_id: sensor.dns_resolver

        data: {}

    mode: restart

    ```

2. Restart Home Assistant to apply the changes.
