EON pushing me to install smart meter after takeover of my collapsed supplier.

Any benefits? or pitfalls?

My simple old world logic says if you use less, you pay less.

How would it help me lower my bills?

Or is it just big brother creeping into last vesitges of freedom and monitoring my moves/ via usage patterns. They will know when I am away on holidays (lack of usage data.)

Anyone managed to avoid such pushy utilities ? Or unavoidable, eventually.
