Hi @Goldsy1947
Thank you for your post.
With smart meters, they only record the usage being used, they can't record or see what devices are being used within the household. They do offer more transparency to your usage as using the AGL app or logging into your My Account, you'll be able to view what your recorded usage is from day to day.
A smart meter can be initiated to be installed in a few ways, the Distribution Network Service Provider (DNSP), may have initiated the exchange if they have determined your current meter to be at the end of it's lifespan.
Thanks, Chris
