If you have a smart TV, you can probably control it with your mobile with its official app. Otherwise, it’s still possible to have rudimentary control over it using a Google Chromecast. What you can do depends on your TV, although at least you should be able to turn the TV off and on again from your mobile.
This can be useful for including your TV in Google Assistant routines, for example, turning off the TV and lights at night or turning it on in the morning to listen to the news. To achieve this you need a few prerequisiteAlthough they are perfectly acceptable if you have a moderately new TV.
1. Use a charger for the Chromecast
The Google Chromecast connects directly to an HDMI port on the TV, although it does need receive power with a USB cable. For convenience, it is possible to connect this cable to a USB connector inside the TV itself, but this has the downside – for our purpose – that when the TV is turned off, it is normal that it does not send power to Google Chromecast.
If the Chromecast isn’t powered, you can’t talk to it. If you can’t talk to it, you can’t turn on the TV. To use these functions, you need The Chromecast stays on even if the TV is turned off. The easiest way to do this is to connect the Chromecast directly to power with its own charger.
2. Activate HDMI CEC on the TV
The way Chromecast communicates with television is far from new. It is based on the HDMI CEC standard which is over ten years old. Obviously this is a way of send control commands via HDMI cable. This way the Chromecast can turn on the screen when you start casting something, or the remote you can control the Home Cinema.
The standard is officially called HDMI-CEC, although different manufacturers they baptize it with different names. Samsung calls it Anynet +, Sharp Aquos Link, Sony Bravia Link / Sync, Toshiba CE-Link, LG SimpLink, Panasonic VIERA Link and so on. In practice, they are all the same HDMI-CEC.
Although it is usual that HDMI-CEC is already enabled, it is possible that on your TV you have to activate it manually the options. In fact, it’s relatively common for the system to not perform too well, so you have to turn the TV off, wait 10 minutes, and turn it back on to get it working again.
3. Ask Google
With Chromecast on, HDMI-CEC on, and the TV off, all you need to do is ask Google while your Chromecast is already set up in the Home app. You can make the request with different words such as Turn on the TV. If the wizard responds with “OK” or something similar, you have configured everything. If that answers you but the TV doesn’t turn on, try disconnecting it from power for 10 minutes, plugging the Chromecast into another HDMI, or checking that HDMI-CEC is turned on.
Not only will the TV turn on live from the Chromecast, and with HDMI-CEC enabled, you will have other perks like turning on the TV and switching to Chromecast source when playing, the ability to pause Chromecast videos with the remote control u obviously also capable turn off the TV with the mobile. Not all controls will work on all TVs, so it’s easier to test which ones work for you and which don’t.
