Home Assistant integration for Grafana Cloud

Home Assistant is an open-source software platform designed for home automation, which enables users to control and monitor various devices and services in their home through a single, user-friendly interface. Home Assistant can run on a variety of devices, including Raspberry Pi, and can integrate with other popular home automation platforms like Amazon Alexa and Google Assistant. This integration connects your Home Assistant instance to Grafana cloud to visualize metrics through a pre-built dashboard.

This integration includes 1 pre-built dashboard to help monitor and visualize Home Assistant metrics.

Before you begin

In order for the integration to work, you must configure the in-built Prometheus exporter for Home Assistant.

At minimum you’ll need to add the prometheus: directive to your configuration.yaml file:

# Example configuration.yaml entry
prometheus:

You will also need to create a long-lived access token which will be used to authenticate the agent with Home Assistant.

Install Home Assistant integration for Grafana Cloud

  1. In your Grafana Cloud stack, click Connections in the left-hand menu.
  2. Find Home Assistant and click its tile to open the integration.
  3. Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Home Assistant metrics to your Grafana Cloud instance.
  4. Click Install to add this integration’s pre-built dashboard to your Grafana Cloud instance, and you can start monitoring your Home Assistant setup.

Post-install configuration for the Home Assistant integration

After enabling the metrics generation, you should instruct Grafana Agent to scrape your Haas nodes.

Haas exposes a /api/prometheus endpoint. To scrape it, add the provided snippet to your agent configuration file.

Make sure to change targets and bearer_token in the snippet according to your environment.

Configuration snippets for Grafana Agent

Below metrics.configs.scrape_configs, insert the following lines and change the URLs according to your environment:

yaml
    - job_name: integrations/hass
      metrics_path: /api/prometheus
      bearer_token: '<your long lived HASS API token>'
      scheme: https
      relabel_configs:
        - replacement: '<your-instance-name>'
          target_label: instance
      static_configs:
        - targets: ['localhost:8123']

Changelog

md
# 0.0.4 - September 2023

* New Filter Metrics option for configuring the Grafana Agent, which saves on metrics cost by dropping any metric not used by this integration. Beware that anything custom built using metrics that are not on the snippet will stop working.
* New hostname relabel option, which applies the instance name you write on the text box to the Grafana Agent configuration snippets, making it easier and less error prone to configure this mandatory label.

# 0.0.3 - January 2023

* Update mixin to latest version:
  - Addressed lint warnings from mixtool

# 0.0.2 - January 2022

* Added `homeassistant` as default metrics prefix

# 0.0.1 - June 2021

* Initial release

Cost

By connecting your Home Assistant instance to Grafana Cloud, you might incur charges. To view information on the number of active series that your Grafana Cloud account uses for metrics included in each Cloud tier, see Active series and dpm usage and Cloud tier pricing.
