I’m getting a syntax error in the frontend Templates page (and what I mean by that is that the output is blanc instead of “false” or “true”).
I’m new to HA and templating so forgive me if this question is something I should know. But why the – 1200 on the last one and not just -1200
anyone managed to add a “snooze” and “off” function? I’m using mqtt buttons with Wemos D1 and Button Shield and also Amazon Dash buttons for various other automations around the house.
A snooze and off function would be easy with two buttons (one for snooze that stops the script for 5mins and then starts it again using a delay. And off is self explanatory) but really id like one button. Anyone have any thoughts about this?
Cheers!
I’m rather new to HA as well and the double minus is just something I figured should be the syntax since equal also must contain 2 “==” instead of 1.
BTW: single minus isn’t working as well
which media_player?
Chromecast (Google Cast)
In many programming languages, a double equal tests for equality, where a single assigns value - even in an if/then context.
Thanks for the tip 
For those who are interested: this did the trick (triggers my automation 20 minutes before wakeup time)
'{{ ((now().strftime("%s") | int + 1200) | timestamp_custom("%H:%M")) }} == {{ states.input_select.alarmtime.state }}'

Nice that you got it to work!
I had a similar problem and solved it a little different:
I created a custom sensor which shows the actual trigger time, i.e. in the example in the link the lights go out x hours after the sunset.
Then I could use the standard compare with this virtual sensor in the automation rule.
If everything seems right then probably your problem is with foreing characters. You should only use the english alphabet in any automation or configuration file. I have ran into this a couple of times, and hass unfortunately does not give any errors just the automation does not trigger.

Thank you all for the examples here, this is great.
Was wondering if someone could post a working trigger that will fire before the alarm time?
I would like to fade in my lights and slowly raise the volume of a radio 15 minutes before what the alarm time is set at in the UI.
I tried last night using the discussion here as a guide but couldn’t get the automation to actually trigger even though double checking my templating in the debug UI appeared like it should have been working.
It works fine using the example code verbatim I just want it to be offset by a few minutes.
Here you go:
- alias: 'Rule 9 - Wakeup Light with Radio'
trigger:
platform: time
minutes: '/5'
seconds: '0'
condition:
condition: and
conditions:
- condition: template
value_template: '{{ ((now().strftime("%s") | int + 900) | timestamp_custom("%H:%M")) == states.sensor.alarmtime.state }}'
- condition: state
entity_id: input_boolean.alarm_clock
state: 'on'
action:
- service: light.turn_on
data:
entity_id: light.bed_room
brightness: 255
rgb_color: [255,255,255]
transition: 1200 P.S I didn’t post the alarm part because of the long script
P.S 2: I just asked the same question a couple of days ago and the answer was just 2 posts above your question
Here is mine:
# Wake Monday
alias: 'WAKE - Monday'
trigger:
- platform: template
value_template: '{{ states.sensor.time.state == states.sensor.sen_at_mon.state }}'
condition:
condition: and
conditions:
- condition: time
weekday:
- mon
- condition: state
entity_id: 'sensor.holiday'
state: '0'
- condition: state
entity_id: 'input_boolean.holiday'
state: 'off'
- condition: state
entity_id: 'group.phones'
state: 'on'
- condition: template
value_template: '{{ (states.input_select.ah_mon.state | int) > 0 }}'
action:
- service: homeassistant.turn_on
entity_id: switch.ebredes

Here is my version… I wanted to set all the days, start and end time.
I didn’t have any coding experience before HA, so I added all my code for my fellow yaml noobs 
ps. just add the times between “02:00” and “22:00”
light:

allow_unreachable: true
media_player:
- platform: sonos

light.bedroom:
state: on
brightness: 230

Many thanks to this thread, I have been using my alarm clock for several weeks and love it. Mine slowly fades in lights and music (selection made by calling a MPD playlist of radio streams) and starts a pot of coffee (the recent WeMo coffee maker addition).
very nice. very nice. add it to the projects section so others can learn from it.
Mine is similar to the others here except that I use sliders to set the start and finish times…
If anyone wants to see the code I’ll post it here
mine reads the google calendar, looks for a meeting called “wakeup” and goes off at that time.
Can you share your config for that?
