[Real record] Can smart speakers be used when cutting on the Internet: Masahiro Yamaguchi's smart speaker life (page 1/2)

　The other day, a power outage occurred in the area where I live.The power outage itself was immediately restored, but in my house, the trouble of the router has made it impossible to access the Internet for a while.

　Because smart speakers are products that operate in cooperation with the cloud, it is interesting to see what kind of behavior in such cases.While the power outage and the Internet line are interrupted, I tried to experiment with both products, Amazon Echo and Google Home.

After the power outage recovery, it is automatically restored, but exceptions

　When the power is cut off, the smart speaker naturally stops.After that, when the power is restored, the power of the main unit turns on, then connect to the network, then connect to the Internet, and restore it in order.

　Therefore, if you leave it as it is, it will return to its original state without permission.Because the power button is not provided in the smart speaker, such operations can be considered correct.By the way, Google Home sounds sound (the same as when setup is completed) when the connection is completed, but Amazon Echo recovers quietly without sound.

　In this way, smart speaker -related products will automatically return to the original state if the power is restored, but only one product that has not been restored from one of the smart home -related devices of the author's house including the smart remote control.be.It is PHILIPS's smart bulb "Hue".Hue was turned off at the time of the power outage, but turned on automatically after recovery.

　There is no problem with the recovery in the lighting state, but the problem was that while the Internet line was cut, it was impossible to operate on / off via a smart speaker at all.

　If so, it seems good to operate with a smartphone app, but in fact Hue and smartphone are indoors, and even if the domestic network is available, if you do not have Internet access, you will not be able to control Hue from the smartphone app.。It seems that the cloud is also intervening here.

　In the case of the author, it was finally turned off using the Dimmer switch included in the Hue starkit, but if you are purchasing Hue's light bulb alone, you may not have a Dimmer switch.In that case, it is two choices, removing the light bulb or pulling out the outlet from the root.

　In this area, if the operation method is a smart speaker (and smartphone app) alone, it may be troublesome in case of emergency.If you combine multiple HUEs to rely on the whole room lighting to HUE, there is a room for consideration.

In an environment where the Internet cannot be used, it is useless

　Another thing I found out in this case is that even if the network in the home has recovered, the smart speaker cannot be used at all unless the Internet access has recovered.

　For example, in the case of NAS, even if there is no Internet connection, if the router is in a state where the IP address is assigned properly, there is no problem in exchanging data with the PC in the same network.

　However, in the case of a smart speaker, even if you only operate a smart device in the same room, it will not work unless there is an Internet line.

　Both Google Home and Amazon Echo just read the message "I don't have Internet access", not only to operate the Hue and the linked smart remote control products, but also read the time, and even use the alarm function.It is a useless long thing.

　The interesting thing is that if there are multiple Google Assistant speakers such as Google Home in the same room, only one at the closest distance will respond to the call, but even in an environment where there is no Internet access, such collaboration will be lost.All devices will reply at the same time.

　At the time of this power outage, in addition to my personal Google Home, I was trying a smart speaker (Sony "LF-S50G", Onkyo "G3") compatible with Google Assistant, but for the call here.At the same time, a phenomenon (exactly the same Serifu) was seen at the same time.It is very interesting that the cloud is intervening in the characteristics of "only one of the closest distance".
