Not exactly, but it is referring to a very specific issue which doesn’t have anything to do with the power draw of the echo itself. You know how we talk about zombie devices, which are ones that draw power even when they are “off”?
OK some smart television models have a “wake on LAN” Which allows them to listen on Wi-Fi for an “on” command even when they appear to be off. Essentially they are in “standby” mode.
The question is how much power does standby mode require compared to actually being off.
And that varies depending on how the manufacturer implements it.
So the study to which the article refers found a few smart television models from the 2017 and 2018 years which are very power inefficient when it comes to their standby mode. And in order to use echo to turn those televisions on, they have to be left in standby mode. So that’s where the Increase in electricity use which they are referring to comes from.
But that’s not how most televisions work, and it’s not the only way to make even those televisions turn on.
So, yes, there are some Smart televisions which, if left in standby mode 24/7, will draw more power than if they are just turned off all the way.
And if you want to use echo with those models and if you want to use the built-in WOL feature, then that probably means leaving it in standby mode all the time.
But the same is true if you want to automate turning them on using WOL from a computer or a Home Automation hub.
The alternative is to use a Harmony hub or similar device that doesn’t use WOL, but uses an IR command Send on demand when you actually want to turn it on. Or use a robot button pusher.
Or at least limit standby mode to the time when you might want to use echo with the television. You could use a smart plug and turn it off completely much of the time if you want.
So A real technical issue, but one which only affects a few people and for which there are alternatives. It doesn’t mean that every echo makes every television use twice as much electricity as it otherwise would, which is what the article implies.
