Hi
Old question but still no answer: I want to activate a script from the GUI. The script does have delay commands. Thus, it is shown on the GUI with a toggle switch. But since this does not make sense for this script, I would like to have the regular “Activate”. I tried to put the “can_cancel” almost everywhere, but this seems not to work anymore?! How can I change form toggle switch to Activate? THX!!
I don’t see that option anywhere in the script documentation.
However, assuming this undocumented option can be used, did you try:
script:
your_script:
can_cancel: false
sequence:
- blah blah...
Yes. But this would have been too easy… 
I also tried to put it on top of RAW Config editor with no success:
script.jalousie_halb
can_cancel: false
Then I guess it is not valid option, as per the docs.
can_cancel goes in customize
homeassistant:
customize:
script.jalousie_halb:
can_cancel: false
OK. But where do I put it if I don’t have customize.yaml (I use UI to configure)?
Copy what I wrote, exactly, preserving the indentation and paste it into your configuration.yaml with the h of homeassistant up against the left edge of the page.
Then save the file and restart homeassistant.
Hey! Thx a lot! This does work!
But it also should be possible to change the value of can_cancel with the GUI (Config -> Customization), shouldn’t it?
No idea, never used the gui for customisation. If you’re happy you did it correctly and it didn’t work but should have, submit a bug report 
Yes I am happy and I thank you very much for your help!
I try to read and understand as much of the docs as I can, but as a non IT guy I sometimes have a hard time to understand how and why things do or do not work within HASS and how things have to be configured properly…
