Set State

Home Assistant Python Script to force set an entity state

How it works

This script adds a service that lets you update the state and/or attributes of any entity, similar to the developer tools

Requires python_script: to be enabled in you configuration

Installation

HACS

Requirements:

• HACS version 0.9 or higher
• Enabled python_scripts: in your Home Assistant configuration
• Enabled python_scripts as option, in the HACS configuration. (If you missed this, kindly read below!)

You are only able to use this custom repo with HACS, if Python Scripts is enabled in Home Assistant. Also, " python_scripts" should have been enabled during the HACS setup through "Integrations" in Home Assistant.

If you missed that part, you need to remove HACS, and add it again, in order to find the "Python Script" category! This time, remember to set a checkmark in "Enable python_scripts discovery & tracking":

Find more information about the HACS configuration here and here. If you used the YAML-way to configure HACS, it's a bit easier. Just edit the YAML configuration for HACS. That parts is also mentioned https://hacs.xyz/docs/categories/python_scripts#enable-if-you-used-yaml-to-configure-hacs.

Manual

Copy the Python script in to your /config/python_scripts directory.

Service arguments

key	required	type	description
entity_id:	True	string	The full entity id to update
state:	False	any	The state value
state_id:	False	any	The state of a other entity
allow_create:	False	Boolean	Allow the entity to be created if it does not exists (Defaults to false so mis-typed entities do not accidentally get created.)
...:	False	any	any additional name becomes or replaces and attribute on the entity

Usage

Each call requires at least an entity_id and a state or attributes (otherwise it wont do anything)

example:

service: python_script.set_state
data:
 entity_id: sensor.random_sensor
 state: "off"
 
service: python_script.set_state
data:
 entity_id: sensor.random_sensor
 state_id: sensor.random_other_sensor
