I have multiple sensors’ data over one year. I wanted to know if there are any unsupervised methods to divide and group sensors’ data that have close characteristics/behavior.

For example, if I have electricity consumption data for 1000 buildings stored in a table with 1000 columns, how I can divide or cluster these columns such that those that have close characteristics are placed in a specific group?

I appreciate your time in advance.

Thank you.
