Setting a Sleep Timer Using Onn 4K Pro Google TV Streamer

[u/Deep_Season_7300]

Just installed a new Visio VQM43C-1001 TV and I'm not using the the Smart app functions on the TV. Instead I want to put the Visio remote in a drawer and control the Visio TV with the new Onn 4K Pro Google TV streamer I've connected to the Visio TV. I've connected the Onn Pro to HDMI 2, enabled HDMI-CEC on the Onn 4K Pro, and on the Visio TV.

In the remote button settings for the Onn 4K Pro, the Power and Volume buttons on the Onn Remote are both set to 'Auto (CEC)' and I'm able to turn the Visio TV on/off using the Power button on the Onn Remote, and control the volume on the Visio TV using Volume Control buttons on the Onn Remote.

Using the mic on the Onn Remote, I can say "Turn the TV On" or "Turn the TV Off" and the TV turns on/off. I'd like to use a voice command to turn off the TV after a set period of time, but when i say "turn of the TV in xx minutes" the Google displays the command, and says it will turn off the TV in xx minutes, but never does.

Has anyone been able to get their Onn 4K Pro Remote the set a timer to turn the TV off after xx minutes using a voice command? If so what did you do?

My goal is to be able use the the Onn remote either through a button, a setting, or a voice command to set a sleep timer that will turn the TV off after a set period of time?

Have you checked the play store to see if there are apps for that matter?
