Hi,
I see this in the logs :
Logger: homeassistant.helpers.script.lichten_keuken
Source: helpers/script.py:1718

Lichten keuken: Already running
What should I look for, cause I don’t have a script “lichten_keuken” ?
This error message is nothing serious, it just shows up, if an automation or script is started while the first run isn’t finished.
But yes, you must have such a script, otherwise it wouldn’t show up in the logs. 
You have the script as Paddy says. If not you would not get the error.
it is in helpers, so have a look at Settings → Devices & Services → tab helpers you´ll probably see it there.
When I do a search of “lichten” I only get these :
I have a light with this name of course (not a script !) :
Raar!
What if you look at Settings → Automations & Scenes and then tab scripts?
Inderdaad raar, vandaar de vraag 
I only have 3 scripts with “lichten” in the name :
It is definitely a strange thing! I cannot think of any location where this might be except for the unlikely scenario you had a script called like that and you removed it without reloading scripts or restarting…
It´s not an issue in reality, but I can imagine it is frustrating not to know.
It’s not only “lichten keuken”, I get the error for my other places too.
I think I know the problem, so I will have a try to change something (trail & error…).
Thanks !
