Creating a alarm clock

jackfrost82 · August 2, 2016, 12:26am

Hi all.
I managed to show the correct value in the tab is the following code:

value_template: '{% if states.input_slider.alarmhour.state| length < 4 %}0{{ states.input_slider.alarmhour.state | int }}{% endif %}{% if states.input_slider.alarmhour.state| length > 3 %}{{ states.input_slider.alarmhour.state | int }}{% endif %}:{% if states.input_slider.alarmminutes.state | length < 4 %}0{{ states.input_slider.alarmminutes.state | int }}{% endif %}{% if states.input_slider.alarmminutes.state | length > 3 %}{{ states.input_slider.alarmminutes.state | int }}{% endif %}'

I tried the code you used but the time I get is 8:0:30.0 any ideas?

I guess I’m having a hard time figuring out what to update on sensor and automation section. Thank you guys!

To fix this, I have created 2 new sensors; sensor.alarm_hour and sensor.alarm_minutes. These will take the value from the sliders and Round it to 0.

Then update the sensor.alarm_time and the automation to use the 2 new sensors.

Here is the complete code.

input_slider: 
  alarmhour:
    name: Hour
    icon: mdi:timer
    initial: 9
    min: 0
    max: 23
    step: 1
  alarmminutes:
    name: Minutes
    icon: mdi:timer
    initial: 0
    min: 0
    max: 55
    step: 5

input_boolean: 
  alarmstatus:
    name: Wake Me Up
    initial: off
    icon: mdi:alarm-check
  alarmweekday:
    name: Weekdays Only
    initial: off
    icon: mdi:calendar

sensor: 
  platform: template
  sensors:
    alarm_hour:
      friendly_name: 'Hour'
      value_template: '{{ states("input_slider.alarmhour") | round(0) }}'
    alarm_minutes:
      friendly_name: 'Minutes'
      value_template: '{{ states("input_slider.alarmminutes") | round(0) }}'
    alarm_time:
      friendly_name: 'Time'
      value_template: '{{ states("sensor.alarm_hour") }}:{% if states("sensor.alarm_minutes")|length == 1 %}0{% endif %}{{ states("sensor.alarm_minutes") }}'

group:
  default_view:
    view: yes
    entities:
      - group.alarmclock
  alarmclock:
    name: Wake Me Up
    entities: 
      - sensor.alarm_time
      - input_slider.alarmhour
      - input_slider.alarmminutes
      - input_boolean.alarmstatus
      - input_boolean.alarmweekday

automation
  - alias: 'Wake Me Up'
    trigger:
      platform: template
      value_template: '{{ now.time().strftime("%-H") == states.sensor.alarm_hour.state and now.time().strftime("%-M") == states.sensor.alarm_minutes.state }}'
    condition:
      condition: or
      conditions:
        - condition: and
          conditions:
            - condition: state
              entity_id: input_boolean.alarmstatus
              state: 'on'
            - condition: state
              entity_id: input_boolean.alarmweekday
              state: 'on'
            - condition: time
              weekday:
                - mon
                - tue
                - wed
                - thu
                - fri
        - condition: and
          conditions:
            - condition: state
              entity_id: input_boolean.alarmstatus
              state: 'on'
            - condition: state
              entity_id: input_boolean.alarmweekday
              state: 'off'
    action:
      service: notify.notify
      data:
        message: 'Good morning. Time to Wake Up!'
        title: ""

I’ve fixed the “.0” problem by using round():

value_template: ‘{{ states.input_slider.alarmhour.state | round(0) }}:{% if states.input_slider.alarmminutes.state|length == 1 %}0{% endif %}{{ states.input_slider.alarmminutes.state | round(0) }}’

I think this is a great example that deserves more publicity.
So it would be great if someone would add it here:

Hi, I just found this discussion. I have a problem with time triggered automation…

Now I’ve edit new configuration, just for testing input_slider and time trigger :

        data:
            message: "{{ states.sensor.alarm_time.state }}"
            title: "message"

Bad news, till now that code didnt work well for me.
But if I changed parameter trigger value to “minutes: ‘/1’”, notification appeared perfectly.

Please help me.

Found a better way to format the slider values:

value_template: ‘{{ “%0.02d:%0.02d” | format(states(“input_slider.peter_hour”) | int, states(“input_slider.peter_minutes”) | int) }}’

nahornyy · September 30, 2016, 3:32am

After upgrade to 29.4 my alarm clock don’t work.
I am use this string as triger:
value_template: ‘{{ now().time().strftime("%-H") == states.sensor.alarm_hour.state and now().time().strftime("%-M") == states.sensor.alarm_minutes.state }}’

masterkenobi · September 30, 2016, 4:08am

Try…

value_template: '{{ now().strftime("%-H") == states.sensor.alarm_hour.state and now().strftime("%-M") == states.sensor.alarm_minutes.state }}'

masterkenobi · September 30, 2016, 6:02am

Here is my latest sample code…

Changes:

Fix now() issue caused by changes in version 0.29
Format the sensor template base on suggestion from @choch (thanks!)
Remove input_boolean.alarmstatus because we can now turn on/off the automation from the front end introduced in version 0.28 (replace by automation.wake_me_up in group)

Sample code:

input_slider: 
  alarmhour:
    name: Hour
    icon: mdi:timer
    initial: 9
    min: 0
    max: 23
    step: 1
  alarmminutes:
    name: Minutes
    icon: mdi:timer
    initial: 0
    min: 0
    max: 55
    step: 5

input_boolean: 
  alarmweekday:
    name: Weekdays Only
    initial: off
    icon: mdi:calendar

sensor: 
  platform: template
  sensors:
    alarm_time:
      friendly_name: 'Time'
      value_template: '{{ "%0.02d:%0.02d" | format(states("input_slider.alarmhour") | int, states("input_slider.alarmminutes") | int) }}'

nahornyy · September 30, 2016, 6:05am

Does not work.
But I noticed - if I move the slider “minutes” to the current time - avtomation work. And if I move slider even for a several minutes forward - automation dont work.

lv-88 · October 2, 2016, 11:44am

Yeah broken here too
On the latest version, and tried the updated code above, but does not work unfourtantly.

masterkenobi · October 2, 2016, 6:58pm

I have updated the above sample code because there was an indentation mistake in the automation.

lv-88 · October 3, 2016, 4:34pm

Hey!
I updated it but it behaves odd, if I press the automation and trigger it from hass manually then it triggers, but when setting a time and all that to let it activate like that then it doesn’t work I tried copying everything you did but ever since I updated hass to latest version it’s a no go, don’t know what else to do

Thanks for being so quick and awesome to respond btw!

nahornyy · October 3, 2016, 5:32pm

I have similar problem

masterkenobi · October 4, 2016, 8:19am

weird. i changed my code back to earlier version and it also failed. Maybe it is a bug in version 0.29.6. anyone has any success?

masterkenobi · October 4, 2016, 9:27am

After further testing, I found out this automation works in version 0.28.2. After I upgraded back to 0.29.6 and change the now.time().strftime to now().strftime, it stop working…

- alias: 'Wake Me Up'
  trigger:
    platform: template
    value_template: '{{ now().strftime("%-H") == states.sensor.alarm_hour.state and now().strftime("%-M") == states.sensor.alarm_minutes.state }}'
  condition:
    condition: or
    conditions:
      - condition: and
        conditions:
          - condition: state
            entity_id: input_boolean.alarmweekday
            state: 'on'
          - condition: time
            weekday:
              - mon
              - tue
              - wed
              - thu
              - fri
      - condition: state
        entity_id: input_boolean.alarmweekday
        state: 'off'
  action:
    service: notify.telegram
    data_template:
      message: 'Good morning. Time to Wake Up!'
      title: ""

Francisco_Pires · October 4, 2016, 12:58pm

What error do you get? I’m having a problem with a similar automation: thread

adi · October 9, 2016, 2:27pm

@nahornyy @lv-88
Did either of you figure this out? I have a similar problem too!

joyrider3774 · October 9, 2016, 3:56pm

template triggers only check for their triggers when one of the entity’s specified in value_template it’s state changes if their state does not change the template trigger value is not checked and no trigger will trigger.

a workaround might be to create a time sensor with hours & minutes and add this sensors in value_template somehow without it having an effect like so perhpas (not tested)

sensor:
  - platform: template
    sensors:
      time:
        value_template: '{{ now().strftime("%H:%M")}}'

and change the value template to include the sensor.time like so for example

value_template: '{{ (now().strftime("%-H") == states.sensor.alarm_hour.state and now().strftime("%-M") == states.sensor.alarm_minutes.state) and states.sensor.time == states.sensor.time }}'

the time sensors state will change every minute so the trigger is being checked at least every minute.

A better way is to use the a time trigger that checks every minute with a template condition

something like (not tested)

automation:
- alias: 'Wake Me Up'
  trigger:
    platform: time
    minutes: '/1'
    seconds: 0
  condition:
    condition: or
    conditions:
      - condition: and
        conditions:
          - condition: state
            entity_id: input_boolean.alarmweekday
            state: 'on'
          - condition: time
            weekday:
              - mon
              - tue
              - wed
              - thu
              - fri
      - condition: state
        entity_id: input_boolean.alarmweekday
        state: 'off'
      - condition: template
        value_template: '{{ now().strftime("%-H") == states.sensor.alarm_hour.state and now().strftime("%-M") == states.sensor.alarm_minutes.state }}'
  action:
    service: notify.telegram
    data_template:
      message: 'Good morning. Time to Wake Up!'
      title: ""
