Ever since I had SM's installed, the indoor display has never provided a
sensible number for the Estimated Cost. It had always just shown the total
cost since it was first installed, adding the cost each month - not taking
into account the direct debits I was paying each month against my account.

So, the indoor display was just left in a drawer, once the novelty wore off.
Last week I gave it another go and once it had synched its data, it was
showing some sensible numbers for this months cost/consumption.

What is more, the estimated cost of both E & G dropped to near zero just
after my DD went out. So it seems my SM's are getting some feedback from my
utility providers system.

Oh, the 'not for long' - I am on the verge of switching to a new
utility supplier, so the SM's will no longer work as SM's.
