Irish water's smart meters block several digits of each consumer's water meter. This makes it nearly impossible for anyone to see their own utility usage. The data is sent via an unpublished protocol to Irish water's meter readers. When consumer's receive a bill, they must believe and pay it, or face fines, legal action and jail.
Some consumers are concerned by the exposure to an unknown amount of RF from the unknown protocol. Others are concerned by the safety of the haphazardly installed meter system or the possibility that the poorly installed meters might be causing leaks or mis-configured meters causing artificially high bills.
The Irish government supports this private company intervening between public water and private users. So if a consumer's remote control or outdoor thermometer on the crowded 433Mhz or 900Mhz bands interferes with the unknown protocol, they are likely to be charged with hacking.
An open protocol would have allowed independent companies to develop inexpensive consumer-focused smart meters which would have helped with the goal of reducing water wastage. As it is now, Irish water decides if and when consumer have access to their own consumption patterns, they will decide what to charge for meter-readers and they alone will determine the accuracy of the flow meters which determine their revenue.
Petrol stations don't regulate their pump's flow meters.
Grocery stores don't calibrate their own fruit scales.
Butchers don't calibrate their own weighing scales.
So why do we let utilities decide how their product is measured?
