Home Assistant Entities Script

Python script for Home Assistant to handle state and attributes of existing sensors and entities. Useful if you need to change a sensor's state or attribute from whithin a script, an automation, or your Lovelace UI.

Installation

You can install this script via HACS or just download hass_entities.py file and save it in your /config/python_scripts folder.

This script use Home Assistant python_script component and you have to add it to your configuration.yaml file.

Usage

1. Set both state and attributes

Name	Type	Required	Description

entity_id	string	Yes	Entity ID of the sensor to be set.
state	string	Yes	The state to be set.
attributes	list	Yes	List of attributes to be set (the actual list of attributes depends on the referred entity).
log_enabled	bool	No	Indicates whether to log system messages to the Home Assistant log (see Logging for further details).
