@Dogwalker You are right, updating tariffs to your home Display is the weakest part of the smart system and very frequently the costs on the display are completely wrong. If you can live with it the meter transmissions should be working and the Display does show kWh and m3 units correctly. The costs on the Display frighten a lot of people who expect it to be their bill, which of course it isn't. I think this is an industry problem, not just SP.
If i unplug the display as you recomind , why sent us this facility ? without it who report you the usage number ? you said my disaplay not correct , but how I can get correct imformation ? just only follow your notice ? thank you for help. the best way is moving away the smart reader , we need to know the correct figour ourself .
