+# Python Scripts
+https://www.home-assistant.io/integrations/python_script
+
+## Example 1
+https://community.home-assistant.io/t/how-to-manually-set-state-value-of-sensor/43975/5
+Scripts are placed in a python_scripts folder under the configuration directory, in my case it is /home/homeassistant/.homeassistant/python_scripts. You then need to either restart Home Assistant or click RELOAD SCRIPTS under Configuration, General, Configuration Reloading.
+
+For what it’s worth, I have been hunting for a solution to this problem and I finally decided to make a small script:
+```
+# python_scripts/set_state.py
+
+#==================================================================================================
+#  python_scripts/set_state.py 
+#==================================================================================================
+
+#--------------------------------------------------------------------------------------------------
+# Set the state or other attributes for the entity specified in the Automation Action
+#--------------------------------------------------------------------------------------------------
+
+inputEntity = data.get('entity_id')
+if inputEntity is None:
+    logger.warning("===== entity_id is required if you want to set something.")
+else:    
+    inputStateObject = hass.states.get(inputEntity)
+    inputState = inputStateObject.state
+    inputAttributesObject = inputStateObject.attributes.copy()
+
+    for item in data:
+        newAttribute = data.get(item)
+        logger.debug("===== item = {0}; value = {1}".format(item,newAttribute))
+        if item == 'entity_id':
+            continue            # already handled
+        elif item == 'state':
+            inputState = newAttribute
+        else:
+            inputAttributesObject[item] = newAttribute
+        
+    hass.states.set(inputEntity, inputState, inputAttributesObject)
+```
+
+
+With this script in place, the action could be:
+```
+  action:
+    service: python_script.set_state
+    data_template:
+      entity_id: Binary_sensor.sensor1
+      state: ON
+```
+
+
+## Example 2
+https://www.home-assistant.io/integrations/python_script#calling-services
+
+Start by enabling the Python script and create the first script.
+    • Add to configuration.yaml: python_script:
+    • Create folder <config>/python_scripts
+    • Create a file <config>/python_scripts/hello_world.py in the folder and give it this content:
+```
+# `data` is available as builtin and is a dictionary with the input data.
+name = data.get("name", "world")
+# `logger` and `time` are available as builtin without the need of explicit import.
+logger.info("Hello {} at {}".format(name, time.time()))
+```
+
+    • Start Home Assistant to reload the script configuration.
+    • Call your new python_script.hello_world service (with parameters) from the Services, using the YAML mode.
+```
+service: python_script.hello_world
+data:
+  name: "Input-Text"
+Running this script show absolutely no output on the screen, but it logs with level info. You must have the Logger enabled at least for level info.
+Your confiuration.yaml should include something like this.
+logger:
+  default: info
+'''
