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.

The reason why this querqy manual time computation is needed is the mqtt automation over Sleep As Android.

The manual time stamp format seems deprected or whatever. That is the reason why some mentioned defaulting to 0 would solve the problem. But it does not really solve it. I could by adding a markup for the time string to begin:
{{ states(''sensor.date'') ~ '' '' ~ manual_time }}
{{ states(''sensor.date'') ~ ''T'' ~ manual_time }}

The two time stamp computation produce different outputs.
{{ as_timestamp(states('sensor.date_time_iso')) }} # 1723102440.0
{{ as_timestamp(now()) }} # 1723098900.217016
I dont know why both are used. But I replaced every occurence of now() with states('sensor.date_time_iso') and it worked.
