How to communicate between projects?

Hi guys, I hope my question isn’t too stupid.
I have 2 projects in my dashboard, I need a relay in project 2 to activate when a variable in project 1 changes.
How do I connect the 2 projects? it’s possible?
Thank you all

I’d suggest you read the documentation about Automations.

If that isn’t suitable, then look at these options…


What do you recommend I look at in the documentation?

Using Automations to Forward Device Data.
