@Oscarmax I read something somewhere earlier it will drop with everthing thats going on.
@phaedra my smart meter does something similar between 12am and 1am. It now resides in the cupboard to protect my health 🙂 I also plugged it back in after seeing of this post and its telling me I have used £2.71 today (17p electric and £2,54 gas) which is BS!
