This is related to the remote switching of appliances,it is however relevant to whether a smart meter is likely to have the facility and the capability of load switching
To meet this challenge, Landis+Gyr have developed the L550 Remote Load Switch, which together with the smart metering solution will enable the utility to disconnect the household load remotely from the smart meter in the street kiosk.
Yes, the technology exists, I don't reject that it does, but it's not in the smart meters that are currently being deployed and therefore is not something to cause concern for UK consumers at this time.
The Remote Load Switch solution is therefore a means for any smart meter that has an auxiliary contact (installed outside the house) to disconnect up to 40 Amp household load/s (situated inside the house)
