I have a Vizio and Samsung smart TV with built in Chromecast. I would like to know, whether I can turn on and off my TV with Google Home speaker with out external chromecast.
I saw many posts this is possible with externally connected chromecast dongle to the TV, would like to know whether this is possible with out external dongle.
If this is possible can some one explains the underlying technology or communication. Thanks in advance.
A CEC enabled HDMI port can send a signal to turn the TV on/off. A TV with Chromecast built-in is not able to power the TV on/off because of how it's integrated with the TV by the manufacturer.
This is not something that Google can change via software it would need to be built in by the TV manufacturer.
Thanks Jake. I am looking for internal details (Underlying protocols or exchange of info) how mobile device (Google Assistant) is controlling TV with chromecast built in.
Not sure whether this is the right group to check. If you can provide any Google partner engineer details to check with hi/her. Thanks.
I wish I could provide you more info, however, we don't have any internal info regarding that. Meanwhile, if you have other suggestions that you want to raise, you can always send us a feedback by following the steps here: https://goo.gle/2NvQG6R
