Trying to submit opening gas meter reading but my 1st generation smart meter does not give me any options apart from kwh but need to submit in m3

that’s because you aren’t reading the actual meter you’re reading the ihd (in home display).
You need to read the actual meter the one on the wall or in a box outside, it’ll appear blank and you need to wake it by pressing a button. It will show you the meter index in m3. Don’t send those kWh readings!
