With mothers house I wanted a gas smart meter, and was told could not have one unless I also got an electric smart meter as well.
The electric meter was under the stairs, and very limited room, the gas meter was installed where it was technically outside, no cabinet to protect it, the porch had a temporary breeze block wall, built to try and keep house warmer, so two front doors, I was surprised they put the gas meter there, but I had left home before it was fitted.
As the time I was against smart electric meters, I was worried about them being remotely turned off, today I have a smart meter, as could not be paid for export without it, but still don't like the idea, as I simply can't read it, I have to rely on the phone app.
I have got it to display some of what is required, I need three readings, off-peak import, peak import, and export, it does not seem to matter what sequence of buttons pressed, never seem to get all three reading.
As long as the app works, not a problem, but really should not be relying on the app.
