Can a node work with more than one home assistance instance?

As per the title.

I’ve set up another home assistant instance for testing and it’s discovered my Esphome nodes that are used with my main server.

What happens if I include them?

They work in both instances.

Thank you.

Just make sure that you won’t set up an automation in test environment, forgot to disable it afterwards and then wonder, why, say your lights go on at certain time and you don’t have ANYTHING set up in main HA… (been there, done that :rofl: )
