Issue with an automation giving an error when HA starts

browetd · November 5, 2020, 12:13pm

Hello

I need your help as I am not finding what’s wrong with the following automations. This first one is not giving an error in home-assistant.log while the second one does (if I am commenting the second automation, the error is gone)… I do not know why … Bug in HA 0.117.4 ?

- alias: send_email_temp_unknown_m
  initial_state: true
  trigger:
    - platform: template
      value_template: '{{ (as_timestamp(states.sensor.h_temp_piscine_m_corrected.state)) < (((as_timestamp(now())) | int) - 1800) }}'
  condition:
    - condition: state
      entity_id: input_boolean.pool_temp_lost_m
      state: 'off'
  action:
    - service: input_boolean.turn_on
      data:
        entity_id: input_boolean.pool_temp_lost_m
    - service: notify.message_ha
      data_template:
        message: '{{ now().strftime("%Y-%m-%d %H:%M:%S   ") }}**** DM-008.1 Température piscine Montréal inconnue... Sending Email to alarm'
    - service: notify.email_to_alarm
      data:
        title: '** HA - Température Piscine Montréal inconnue **'
        message: '**** DM-M001.1  {{ states.sensor.date.state }} {{states.sensor.time.state}} ****'

Here is the error when HA starts (no error after that):

See the warning here: https://www.home-assistant.io/docs/configuration/templating/#states

Thank you @tom_l … So I changed the two automations to take into account the warning you referred to but the error remains at startup… Second automation is now:

#=================================================================================================
#
# Automation for MONTREAL

#

- alias: send_email_temp_known_m
  initial_state: true
  trigger:
    - platform: template
      value_template: "{{ (as_timestamp(states('sensor.h_temp_piscine_m_corrected'))) > (((as_timestamp(now())) | int) - 1800) }}"
  condition:
    - condition: state
      entity_id: input_boolean.pool_temp_lost_m
      state: 'on'
  action:
    - service: input_boolean.turn_off
      data:
        entity_id: input_boolean.pool_temp_lost_m
    - service: notify.message_ha

Put this in your template editor and tell me what it returns:

{{ (as_timestamp(states.sensor.h_temp_piscine_m_corrected.state)) }}

I suspect what you really want is the last_changed property.

{{ (as_timestamp(states.sensor.h_temp_piscine_m_corrected.last_changed)) }}

browetd · November 5, 2020, 5:39pm

state: 1604597520.0
last changed: 1604597901.653089

tom_l · November 5, 2020, 5:42pm

Huh. Ok. When I tried the first template with one of my sensors I got : None.

browetd · November 5, 2020, 5:52pm

OK… but the entity is a date and normally changing every 20 minutes…
example of states.sensor.h_temp_piscine_m_corrected.state: “2020-11-05 18:39”

in the trigger, the template is identical for the two automations except the “>” and “<” but I only have one error for the second automation…

tom_l · November 5, 2020, 5:54pm

That would explain it. I’m out of ideas.

browetd · November 5, 2020, 6:35pm

I have no idea neither… I changed the automation as a work around to avoid the error…
The automation is like this now :

#=================================================================================================
