All the same, I don’t think I’ll be buying one of these remote controls because our set-up is rather different from yours. We don’t have a desktop, just laptops, and we always switch these off before we go to bed. We use the printer rarely enough that we only switch it on when we actually use it, rather than leaving it on in between times. The same goes for the wireless keyboard and mouse (I hardly ever use them these days, if I’m honest. I should probably get rid of them) and we don’t have a desk light (not that you’d leave that on overnight anyway). The only things on your list that we leave on overnight are telephone and router, and I really don’t believe they use enough on their own to be worth switching off.

As we have an electric shower (7 kW), the simplest way I’ve reduced my electricity consumption is to take shorter showers. I’m also careful to only fill the kettle (3 kW) with as much water as we need. If it’s slightly too little, it takes no time to boil a little more water to top up the mugs. If there are high-power devices we can cut down on, that’s going to have a much bigger impact on our total usage than lower powered things like routers and phone chargers. Those electricity monitors are very useful for finding out which is which.
