Need to access time sensor

alternatively, use now


template:
- trigger:
    - platform: time_pattern
      seconds: "/1"
  sensor:
  - name: time
    state: "{{ now().strftime('%H:%M:%S') }}"

{{ now().strftime("%I:%M %p") }}

{{ as_timestamp(state_attr("device_tracker.android_9050f88e39898022", "last_time_reachable")) | timestamp_local }}
{##{{ state_attr("device_tracker.android_9050f88e39898022", "last_time_reachable").strftime('%H:%M:%S') }}##}

  - condition: template
    value_template: '"{{ now().timestamp()+300 < (as_timestamp(state_attr("device_tracker.android_9050f88e39898022", "last_time_reachable")) | float) 
 }}"'

# 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
'''
