Hi
I created a sublfow with string property lux_entity. This property will hold the id of a sensor entity I want to use in the subflow, but how can I acces this property? This isn’t working:
I also tried {{lux_entity}} but that didn’t work either. Am I doing something wrong or is this just not possible?

Hi, I don’t know if there is a better way, but the following works for me.
With {{foo}} you can address anything within msg context, so you can put a change node before your current_state node, that copies the env var into msg context:
Then you can use {{lux_entity}} in current state node:
Thanks for your creative suggestion 
For some reason, it still doesn’t work. I send the message to the output, but msg.lux_entity is an empty string. It’s as if the settings aren’t there. I triple-checked for typos but everything looks fine. This is the flow I’m testing with:

You have a typo in property definition of your subflow:
Oh my god. I must have checked a dozen times! How silly. Thanks for your patience and help!
Sidenote: once spelled correctly, ${lux_entity} started working as well.
Haha, nice one
