I’m not sure this is true… That’s like saying it’s OK to enter someone else’s house because they accidentally left the door open. Just because it isn’t encrypted doesn’t mean it’s meant for you to listen to.
Edit: I was under the impression that most smart meters used 4G (at least in the US)… Pretty sure it’s illegal to listen to cell communications.
They use an open frequency, not the cell network. You can use an inexpensive rtl-sdr to monitor them. People do it all the time to integrate their meter with home assistant.
It’s no different than looking at someone’s WiFi network name.

Actually wire tapping is illegal but listening to radio frequencies isn’t. Go figure.
