A new smart meter is tripping RCD for 7 hours every night & I have a theory

Dont agree with the comment about the neutral. We have loads of THTC or economy 7 stuff up here and the neutrals are marshalled together in a Henley block.

If the RCD can’t be reset for 7 hours The issue has to surely be connected to the off peak supply in some way if that is switching on/off at these times?

I’m sure the neutral has to be capable of being isolated via isolator which doesn’t interfere with normal supply which provides disconnection solely of the off peak other than affecting the on peak supply I had similar issue couple of years ago when installing a lot of storage heaters on a nationwide contract experienced so many different types of supplies
