Description
A blueprint to upload Home Assistant sensor data to WUnderground.
The WUnderground data upload for weather stations is based on a GET request, so it is possible to achieve these results within an automation.
Yes, I know. WUnderground pulled a free service down, but I support the idea of a community based weather station.
This blueprint needs to execute a shell_command. This service needs to be enabled with, for example, the following YAML.
shell_command:
curl_get: 'curl -X GET {{ url }}'
Disclaimer
The blueprint is created because the Netatmo to WUnderground upload isnât working (itâs possible in the WUnderground âadd stationâ wizard, but fails). The sensor data is formatted based on the information in my available sensors and unit_of_measurement values, so there could be a bug in formatting.
Blueprint
blueprint:
name: WUnderground upload
description: >
Upload data from Home Assistant to WUnderground.
Config:
The station_id and station_key variable must be fetched from WUnderground.
The sensor_* variables are the sensors whos data will be uploaded
The trigger_entities variable specifies the entries to trigger state changes on (this could be a list)
The curl_command_service variable specifies the CURL-service to execute.
The refresh_frequency variable specifies the frequency the sensors update their data
The dewpoint temperature can be calculated based on the outdoor temperature and the outdoor humidity.
By default, it will be calculated, to disable this set calculate_dewpt to false.
The CURL-service must exist in Home Assistant.
This can be configured with the following YAML
shell_command:
curl_get: 'curl -X GET {{ url }}'
