I am curious about this, too. The electric company in my area offers energy assessments with access to smart thermostats to replace the manually programmable thermostats and other energy-saving modifications, appliances, etc. From what I see online, they started rolling out smart meters in 2018. I don’t see how a smart meter would be able to make homes more vulnerable to intruders, etc., but restricting electricity to a home seems very feasible. Troublesome, indeed.
