zacs master i though the smart meter (i have one) is not the plug and play monitor but the actual meter in the electric box or wherever the power comes into your home , this is from an energy supplier.........
"Having a smart meter doesn't affect your right to switch energy providers whenever you want. So if you've had a smart meter installed but you want to move to a new supplier, you will still be able to do so. However, you may find your smart meter loses its functionality and reverts to being a traditional meter."
