There are new devices on the market that want to enrich and control the smart home. Furthermore, you can use them – more or less well – to sound your own four walls. All of us are now using much more connected devices than we did a few years ago, which can be cameras, network storage, repeaters and, of course, smart assistants.
However, maybe we like to forget that the boxes not only mean acquisition costs, but generate running costs through electricity consumption. Even though it is often only a few cents – several devices lapping each other and thus generate considerable costs every year. Example: I have measured here with me the Google WiFi times. In the best case costs 10 Euro per year.
I currently have four connected – are already 40 euros a year. And the power consumption of Amazon Echo of the first generation, Echo Dot and Google Home, I have already measured here in the blog (links at the end of the article). Also consume electricity and that too can loll.
It is well known that even the small fish stink. So I grabbed the new Amazon Echo of the second generation, plus the new Echo Plus with Smart Home Hub and, exceptionally, the Multiroom loudspeakerOne, since it's now also on the (Alexa-) Hear word and thus fit in the round.
To consider: The information is of course not 1: 1 applicable to you, since everyone uses the boxes with varying frequency in varying form and volume. But who likes, can indeed calculate the minimum consumption on the year. I once took the base price of 30 cents per kilowatt as a basis.
Power consumption Amazon Echo second generation
Let's start with the second-generation Amazon Echo, Amazon's new Smart Home Assistant. He consumed in my standby 1.9 watts. I asked him what and he answered at 50 percent volume, so I came on average to a consumption of 3.7 – 4 watts. Music was played at this volume at a consumption of 2.9 watts. At 100 percent, consumption was around 4.7 – 5 watts. If you would not address the device permanently for one year and only leave it in standby, that would be around 16.60 kilowatt hours per year. If one assumes 30 cents for one kilowatt hour on average, this is 4.98 euros . Not included in this calculation are different prices for night and day electricity and use, but only costs for standby of the second-generation Amazon Echo.
Power consumption Amazon Echo Plus
Let's go to the Amazon Echo Plus, the big speaker with a smart home hub. He consumed 2.4 watts in standby, with questions and answers he came at 50 percent volume to 4.3 to 4.6 watts. Music at 50 percent consumed 3.9 watts on average and the probably never used volume level of 100 percent made for 6.8 to 7.2 watts. Does annual standby cost of 6.29 euros at just under 21 kilowatt hours consumed. Interesting: In a direct comparison, the first echo consumed more on standby at that time.
Power consumption Sonos One
Finally Sonos One. The best in my comparison in terms of sound Alexa-tailed speakers. The has a good humming and volume and of course makes the power consumption noticeable. The Sonos One uses in standby with me 6.4 watts. That's 55.91 kWh in the year or just 16.77 euros per year. When answering questions, the Sonos One came to 7 -7.3 watts. At a volume of 50%, the Sonos One settled down when listening to music at about 7.8 watts of consumption and if I put the speaker to full power, then it sometimes likes to 17.4 to 18.5 watts.
The whole thing can of course continue for any device – and the more devices we have, the more it costs us. As mentioned above: The mentioned consumption is certainly not representative, since everyone uses his assistant differently, but you can Maybe not completely disregarded, but then you get someday surprisingly pushed a back payment to the eye.
