I regard them a a security weakness as it allows the supplier to
determine when the house might be unoccupied.

The entire days data is sent once per day, at around midnight. At best
it only suggests when the house 'might' not have been unoccupied (past
tense), rather than when it will be unoccupied. However, what use would
such current knowledge be to an energy supplier, for those who are less
paranoid?

Someone on the suppliers staff might make use of the information. Much
less energy is used when the property is unoccupied. No fridge or cooking.
