1 I am in UK. I was 'offered' ( take it or we may disconnect you!) smart meter connection. I investigated how smart meter woul call home by landline or Wifi phone signal. It turns out the mobile phone company being used by utility does not provide a signal in my area and meter does not retune to another phone company who have a very poor but available signal in the area.
2. Final solution copy letter to my member of parliament, copy to utility supplier. No smartphone to be installed , old fashioned one left. hand read by man during 3 monthly visit.
3. Second problem, UK Government wants you to be able to change utility suppliers, smart meter can only work with one supplier as it is tied to their ISP, so to change utility supplier means old hand reading and a change of meter! Real mess up.No one phone company covers more than 80% of availlable households/companies by mobile phone signal. 90 % odd by different mobile phone companies which is why I use two phones to get cover at work and at home.Only the land line due to universal provision in law (like post office mail deliveries) can go to each 'registered dwelling'. This does not cover all 'business premises' who can only get landline by business agreement.
