Smart Meter

I have a Liberty 100 meter that was supplied by 2016 I have now switched from Co Op Energy and have been submitting to them Electricity day and night readings using RO1 (night) and RO2 (day) readings. Today I find RO2 day readings are not availaible is there any explanation for this as it is a complete pain. I have had to obtain the total used and subtract the night reading but it all seems very complicated! Are Bulb going to supply a new and simpler meter this year as I wish I hadn’t asked for a smart meter to begin with now!
