This template breaks randomly and starts to use the default value to turn randomly on.

This template part is failing when there is no next alarm set and the default value is used.

condition: template
value_template: >-
{{0 < as_timestamp(states(sensor) if sensor != 'none' else
states('sensor.date') ~ ' ' ~ manual_time) - as_timestamp(now()) <=
float(seconds) and states(check_entity) in ['unknown', 'on', 'home']}}

This should not happen:
there is no alarm set for the sensor and i dont want to be woken up every day at fixed time!

@sbyx , I am getting the following error when using this blueprint:

Stopped because an error was encountered at September 21, 2022 at 9:40:00 PM (runtime: 0.05 seconds)

In 'template' condition: ValueError: Template error: as_timestamp got invalid input 'unknown 21:45:00' when rendering template '{{0 < as_timestamp(states(sensor) if sensor != 'none' else states('sensor.date') ~ ' ' ~ manual_time) - as_timestamp(states('sensor.date_time_iso')) <= float(seconds) and states(check_entity) in ['unknown', 'on', 'home']}}' but no default was specified

Any chance you'd be able to help?

I'm new to HA, and transitioning from a Hue hub, and this blueprint makes this possible (with caveats)!

1. I'm using some helpers for setting the time, but the blueprint can't use the helpers. I had to work around this in a weird way
   https://community.home-assistant.io/t/wake-up-light-alarm-with-sunrise-effect/255193/305

2. Any chance this could take multiple Additional entity to check before sunrise is triggered ? This would allow much more flexibility with whether or not it should run.

3. Any chance this could be modified to have a manual_sunrise_duration, with an if/then for the input from a number helper?

I'd like to be able to make my dashboard easier for my wife to mentally digest.

Right now I have

But I'd like her to be able to adjust the duration from here, as well as I'd have the ability to cleanly do some time math to indicate what time the lights will start based on the duration.

This is great, but doesn't work well with snooze for me. If I have a sunrise time of 30 minutes, snoozing 5 minutes causes weird things to happen, i.e. it tries to turn on the brightness again. Would it be possible to have it ignore alarms that are too soon? I don't need it to act on any alarm that is less than the sunrise length into the future. I've tried to figure out how it works and implement it myself, but I don't understand all the script magic that is happening...

Being able to use rgb lights by starting with red at the beginning would be great!!

Hi @sbyx, thanks for sharing this automation. As a newbie at home assistent I was wondering if it where possible to run this automation for more than one alarm.

It so happens that we have more than one person in home in dire need of getting all possible assistance waking up. I've tried to run two instances of this blueprint but since the mode is single the execution seems to stop.

The simple solution would be to change the mode to parallel but I'm not sure if that would cause problems executing this blueprint.

Any thoughts?

So, taking some time to actually read the documentation I understand that this is probably not the root cause of my problem. I'll do some experimenting this weekend to resolve the problem I had (or thought I had).

@Erfa Did you find a soluion for the snooze?

I also came across this issue and I think it's kind of logical. When you snooze your device stops the current alarm and sets a new one 5 minutes later (snooze time). Then when the blueprint triggers the next minute it detects the new alarm and sets the light to the brightness value appropriate for 5 minutes before the alarm will go off.

I've solved it by adding a post-sunrise action in the form of a 25 minute delay. That way, when the alarm goes off the first time, the automation will keep running and because the automation will only restart if the current execution is finished. So if you snooze more than 5 times (5 snoozes of 5 minutes each) you will probably see the stuttering light again.

in regards to use RGB Lights with Red, Orange, Warmwhite, White Sequence, it seems another Project has done this calculation already:

https://community.home-assistant.io/t/sunrise-simulator-wake-up-gently-to-light/493778

The reason could be that that I updated my home assistant recently, but currently this blueprint doesn't work anymore for me.
It keeps waiting at the second wait sequence.

When I debug the lines of code and simplify it a bit, I see it has to do with the timezone

In the screenshot, I set the next alarm at 23.20 and the current time is 23:06. With a sunrise time of 20 minutes, the value should be true already.
When I subtract the next alarm time and current time, I end up with a negative number. This is due to the fact that the next alarm time is not converted to my timezone (+2) when it is converted to a timestamp.
With my limited programming knowledge I tried everything to make the conversion right, but I didn't manage yet.
Oddly enough that this has worked in the past....
Anyone any idea on how to solve this?

Same problem for me.

Same for me .. stopped working since the last HA update :(

In 'template' condition: ValueError: Template error: as_timestamp got invalid input 'unknown' when rendering template '{{0 < as_timestamp(states(sensor) if sensor != 'none' else states('sensor.date') ~ ' ' ~ manual_time) - as_timestamp(states('sensor.date_time_iso')) <= float(seconds) and states(check_entity) in ['unknown', 'on', 'home']}}' but no default was specified

Has anyone managed to repair it themselves?

FIXED the error!
Heres the fixed Blueprint. Works only with sensor. Manual timesetting is not supported.

Change this part of the code:

action:

• wait_template: '{{sensor == ''none'' or as_timestamp(states(sensor), None) != None}}'
• wait_template: '{{0 < as_timestamp(states(sensor) if sensor != ''none'' else states(''sensor.date'')
  ~ '' '' ~ manual_time) - as_timestamp(now()) <= float(seconds)
  and states(check_entity) in [''unknown'', ''on'', ''home'']}}'
• choose: []

basically changes as_timestamp(states('sensor.date_time_iso') to: as_timestamp(now())

I don't understand why this blueprint uses this idiom of states("sensor.date") ~ " " ~ manual_time to construct a string for "today at the manual_time time".

today_at(manual_time) returns an equivalent value, except that it has the timezone offset attached. But since this blueprint is always using these strings as parameters for as_timestamp(), these are all equivalent:

{{ as_timestamp(states("sensor.date") ~ " " ~ "07:01:00") }}
{{ as_timestamp(now().date() ~ " " ~ "07:01:00") }}
{{ as_timestamp(today_at("07:01:00")) }}

I'm testing a variant that doesn't need sensor.date and sensor.date_time_iso, have a look at https://gist.github.com/triplepoint/1b9006ddec208a07fc0100a2a30110eb

@triplepoint Works for me! I owe you a big thanks!! My setup is working again.
