I'll reinforce what Roger has said..
All of VM's TV boxes are designed to be left connected 24/7/365, and updates are often pushed out overnight. Repeated on/off cycles are likely to cause problems sooner or later.
Use the power-saving options under Home > Help & Settings > Settings > Devices > Power saving. If you want to be able to access your V6 remotely to manage recordings, then don't use Eco-low-power.
