No. This is the best I could find it explained.

That is one of the oft-discussed consequences of smart meters, yes.

Because they measure at a far higher granularity (sample rate) it is relatively easy to identify the use of electric ovens, kettles, refrigerators etc. The consumption of a computer is likely to be steady over a lengthy period - even continuous if it is never switched off. Heaters of any kind tend to have a duty cycle in several minutes because most thermostats are on-off controls; and TVs tend not to be on much outside peak viewing periods.

One justification is to offer you advice - such as putting computers on standby when not actively in use - t o save you money.
