Same issue in Quebec (Canada). I didn't have a choice in my home. Either I let them install the e-meter, or I would have to pay Hydro Quebec $200/yr to keep my old, functioning very nicely for 15 years, mechanical meter.
I check my bill every month to see if there's some differences from the previous month or same period the year earlier, but so far, knock on wood, nothing amiss so far.
I am, however, ticked at the craziness of it all. These eMeters are more expensive per unit that the sound mechanical ones, they haven't been around long enough to give anyone a good idea of mean time to failure (MTTF). I've worked with embedded (now called IoT) devices for 20+ years, and no electronic device I've ever heard of has even 1/2 the MMTF of it mechanical device it's supposed to replace.
Not only that, but it contributes to additional wireless radiation and congestion on the wireless frequencies it uses to bunny hop to the closest meter or concentration point.
I can ramble on, but this is just another reason to hate these things.
