--- title: Emoncms History description: Instructions on how to integrate Emoncms history into Home Assistant. ha_category: - History ha_iot_class: Local Polling ha_release: 0.31 ha_domain: emoncms_history ha_integration_type: integration --- The `emoncms_history` integration makes it possible to transfer (write) details collected with Home Assistant to [Emoncms.org](https://emoncms.org/) or your local running Emoncms instance. It will send the data to a specific input node on Emoncms with the entity IDs as a key. Afterwards you can create feeds and dashboards in Emoncms with the collected data. To use the `emoncms_history` integration in your installation, add the following to your `configuration.yaml` file: ```yaml # Example configuration.yaml entry emoncms_history: api_key: YOUR_EMONCMS_WRITE_API_KEY url: https://emoncms.org inputnode: 19 whitelist: - sensor.owm_temperature - sensor.owm_wind_speed ``` To read information from Emoncms to Home Assistant, you can use the [`emoncms`](/integrations/emoncms) integration. {% configuration %} api_key: description: The write API key for your Emoncms user. required: true type: string url: description: "The base URL of Emoncms, use for the cloud-based version.
