How to get last_updated and last_changed from api back into HA?

RobDYI · April 19, 2017, 1:56pm

I noticed that the HA api gives last_updated and last_changed to the device trackers but I can’t find away to find those values in HA. I will need to write a python script to access HA api and return those values to a HA command line sensor. Is there a better way to get these values into HA for automation / frontend?

Do you mean like this?

Danielhiversen/home-assistant_config/blob/303038b24218005db3a3a3c71f5f6ac059fc07f9/automation/heating.yaml#L20


    entity_id: sensor.relative_alarm_time
    below: 30
  - platform: numeric_state
    entity_id: proximity.home
    below: 1300
  - platform: numeric_state
    entity_id: proximity.home
    below: 100
condition:
  - condition: template
    value_template: '{{(as_timestamp(now())-as_timestamp(states.sensor.target_temp_stue.last_updated)) > 900}}'
  - condition: template
    value_template: '{{float(states.input_slider.auto_temp.state) > float(states.climate.termostat_stue.attributes.temperature)}}'
  - condition: state
    entity_id: input_boolean.auto_heat
    state: 'on'

  - condition: or
    conditions:
    - condition: template
      value_template: '{{ trigger.entity_id !=  states.sensor.relative_alarm_time.entity_id}}'

Exactly, thank you.

Is there a way to turn a WARNING into a notification?
I just realized some of my automations were not working and I looked at “INFO” and found:
2017-09-02 18:16:53 WARNING (MainThread) [homeassistant.components.sensor] Updating scrape sensor took longer than the scheduled update interval 0:00:clock1030:
This happens regularly with the Scrape Sensor. Is there a way to turn this into a notification?

Spent an hour to conclude that this Jinja2 style check
‘{{(as_timestamp(now())-as_timestamp(states.sensor.target_temp_stue.last_updated)) > 900}}’
is impossible to make in python_scripts because hass object is super sandboxed:

can not get last_updated attribute, actually get does not work at all
as_timestamp als no available from utils package

After debug of python_scripts in HA I can glue the wallpaper through the keyhole.
