All your YAML looks good, just check your timer helper. Below is my one for your reference. Note the duration and the restart must be ticked so it will survive a HA restart.
Let us know how you go.

I have the timer set the same. This is a trace that happens when the timer stops and the climate should be turned off:
I’m not sure which parts of the trace are useful.
This is step details:

For the sake of testing, I’ve set the run time for 10s.
It does not work just for the climate. When I change the boiler climate with a switch it works great.
Should I send you anything else?
I see, I will PM you.

Hello !
Many thanks Blacky for this really nice blueprint.
I wanted to develop one but yours is so advanced I gave up mine 
I would like also to add a condition (SUN condition).
How I could achieve this in your opinion please ?
My use case:
- 3 triggers (1 helper “button”, 1 switch, 1 motion sensor)
- the entity to turn on is a light
- I would like to switch on the light when a trigger is activated AND during night only
Another request:
-
could you add a notification system before and after the action ?
For instance, a notification is sent via Telegram or other solution before the light is switched on and another notification after it is back to off. -
last question: how do you display remaining time of a timer please ? I can display the duration of the timer in a card but not the remaining time.
Thank you again !
Hi again,
I’m still testing your blueprint. I’m facing an issue when I use a timer helper:
Everything goes well until the timer is over:
When I click on the trigger-button, the timer looks good:
At the end of the timer, the light doesn’t switch off and in the log:
homeassistant | 2024-02-23 08:45:04.024 WARNING (MainThread) [homeassistant.components.automation] Error evaluating condition in 'Test timer bureau':
homeassistant | In 'condition':
homeassistant | In 'or' (item 9 of 10):
homeassistant | In 'and' (item 3 of 3):
homeassistant | In 'template' condition: UndefinedError: 'dict object' has no attribute 'entity_id'
I don’t understand my issue… 
Thank you in advance !
It is probably because you are using a device and not an entity. But have a look at this blueprint 
Manual light control with auto OFF it may be more inline with what you are trying to do.

Hi,
Many thanks !!! I changed to an entity and now it works perfectly !! 
The blueprint you mentioned is not totally what I’m looking for, but I keep it 
Thanks !
