Sky Q, Mains off or not?

Hi, Sky Q when turned to standby by Remote Control is consuming 20-40w of electricity all night. Equals about £65/yr over 24hrs a day.
If set to ECO mode, consumes 0.9w, so a lot cheaper, but mine loses internet wifi connection every day and needs a reset, which is a pain.
Does anyone out there routinely turn their SKY Q off every night at the Mains? And if so, are there any negative effects on operation?
Thanks
