It's not illegal to monitor someone's smart water meter as it's not encrypted. You can tell whenever they shower or go to the bathroom and then send them a log of their activity. It's not illegal
In Transformers: Age of Extinction, a 20 year old man shows the father of a 17 year old girl a laminated card of a Texas State law to justify him being in a sexual relationship with the 17 year old girl. This actually happens in the movie.
Always wondered what stalking actually was - I mean paparazzi seem legally well protected.
A new (June 2023) US Supreme Court “standard essentially brushes a street protester with the same stroke as a persistent obsessive who subjects someone to intense and long-term technologically enabled abuse”. Oof.
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.
Better yet, sell their showering activities to shower head manufacturers, and the NSA. Idk why the NSA wants to know when you shower, but I guarantee they do.
