With a decent firewall, you could also apply a rule to ensure that the SEWER VLAN is blocked from communicating with the Internet and blocked from communicating with the local network. Problem solved.
Luckily, we don't have smart meters here, yet. But if they do, they won't be joining our home network, without a written TOS which includes information about timely update policy and a guarantee for compensation in the case that their device attacks my network. If they want it to phone home, they can pay for their own damned connection!
