This repositority provides templates and a shell script to create Current, Daily, Hourly, and Alerts Sensors for Home Assistant using a One-Call API-KEY from Openweathermap.
A REST Call to the Openweathermap API is used to create an HA entity called openweathermap_report. The JSON data from the REST Call is loaded into an entity attribute. Then template sensors parse the attribute for their specific data.
Entity naming conventions follow a mashup of the legacy Dark Sky, and the Openweathermap approaches. That is, Dary Sky used temperature_0d, Openweathermap uses temp for temperature. This uses temp_0d.
The build is modular and controlled by the createopenweather shell script. The script is a series of mostly sed commands that take master files, set the desired day or hour, and append them to the openweathermap.yaml package. Edit the script to change the number of days/hours, etc., or to eliminate a whole category, for example, hourly.
Scroll through the yaml files. To change naming conventions, or to exclude certain weather attributes, just edit the openweathercurrent.yaml, openweatherhourly0.yaml or openweatherdaily0.yaml files.
You MUST edit openweatherheader.yaml to specify your ONE-CALL API_KEY, your Latitude and Longitude, your Units, and Language along with any elements you desire to exclude from the data requested from the API (for example minutely). After editing, pasting the https:... string into a browser should return a JSON result.
Icons are managed in their own, openweathericons.yaml file. There are keys in the current, dialy0 and hourly0 files that indicate where the icon entity should be included by sed. Each day, each hour, and current conditions all need their own set of icon mappings. This approach allows easy remapping or adding of addtional icons in one place.
To use metric UOMs edit the yaml files and change the UOMs as needed before running the script. Also, change the units key for the api call in the header file to metric from imperial. Note that the precipation data are always returned in metric units for some reason. They are divided by 25.4 in the yaml files to convert from milimeters to inches. Search for 25.4 and modify the equations for metric.
Download the files into a directory like /config/opw_elements. Running the createopenweather shell script then creates a HA package named openweathermap.yaml in /config/packages/. For this to work your configuration.yaml file needs to have the line:
packages: !include_dir_named packages
or another similar include directive. See HA documentation for packages.
