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.

Have a look at: https://gist.github.com/Delvint/a4203ab90ec3000c590acb7bf16f6d86

Sería posible añadir que además de las luces, en paralelo, se conecte la música de un 'media_player'? No se si es posible ahora mismo

Would it be possible to add that in addition to the lights, in parallel, the music from a 'media_player' is connected? I don't know if it is possible right now.

I have this a Post-sunrise action, you could do it pre-sunrise.
