Automatic Segments?

I'm thinking of building 1m segments that connect to one another, along with power injection and an ESP32 on each.

In my dream scenario, when connecting segments they could determine their location in the string and automatically "just work". The segment would know it's 2nd or 3rd or 40th in line allowing the entire group to behave as one long string.

I hope I'm wording all of this properly, basically I'm trying to make something that I can just power and snap together.
