Every night when the cable box updates, the TV turns on.
Every night when the cable box updates, the TV turns on. I've changed the update time and that hasn't stopped the problem, it just happens at the new time. This has been going on for about a month.

@user_79a1fb While you can't prevent the box from updating, you can go into your box's settings and turn off HDMI-CEC. This setting allows your box to turn on your TV. You can reach that setting by going to Settings > Device Settings > Power Preferences > HDMI Device Control (HDMI-CEC) > Off or On. This setting is turned on by default.

I see that for the last month, you have been experiencing issues with your TV turning on every night when the cable box updates even after changing the update time. Rest assured, our team is here to help. We'd be happy to run through some troubleshooting steps. To start, may I ask what type of equipment you are using? If you are unsure, I have included the following link for reference https://www.xfinity.com/support/articles/x1-hub-vs-companion-box. How long have you had your equipment?

@user_79a1fb No, turning off HDMI-CEC will not stop the remote from turning the TV on and off. That's done through codes sent by IR from the remote to the TV. CEC uses commands sent over the HDMI connection between the TV and Xfinity box.
