This is not set in the doc but you can assign the same marker several plugs (two plugs A for example) will be managed by the same button A.
Otherwise, there are two aspects to consider: comfort and economy.
Comfort, power cut without getting up every day before TV displays and other players who pollute the night it's awesome.
Side economics, I have found a permanent consumption of 5 Watt, whether on standby or in use.
It gives 120Wh per day, roughly for each takeover, 44kWh per year (6 euros). Do not abuse it so ...
Depending on your equipment and the standby time, I leave you your own calculation of the economy (or over-expenditure) ...
For my part, I found that my TV + box player totally consumed nearly 25W standby:
- It therefore falls to 5W by activating the remote control;
- It goes up to 30W if you forget to use the remote control;
- It falls to zero if we get up and we unplug everything by hand :-)
