I notice that the In-House display unit draws just over 50mA of electricity. While that doesn’t sound much, it equates to 12W which in a year will cost around £20!
Mine is now binned!
Now I am wondering how much power the actual smart meter uses. There’s a lot more circuitry in it plus it transmitting via mobile phone network etc. I wonder which side of the meter it’s drawing power from, ie: am I paying for that too?
