I received a new xfinity flex box. Finished setup and everything is working fine. Its remote is paired only with xfinity flex box and not controlling any other device including TV. When I press power button on the flex remote, it does not power off the flex box. If I try "power off" voice command, I see an error message saying that I can not control the TV yet. I am not expecting the remote to control the TV as I have not paired. I was expecting the flex box to power off but does not. Remote's all other operations/button work fine. One of the online chat support did the usual troubleshooting, reset etc and told me to go to store and get a new remote. I did that. Its the same even with new remote. Then another chat support went through the same troubleshooting steps and transferred to his boss. Then this boss did the same troubleshooting steps and gave up !! he said he has to send a technicial to home. I have no time to wait for the technician who probably will give me a 3 hour window on a working day for this small thing. Before I go to the store and exchange the box to a new one, I wanted to post here and see if anybody knows what's going on. It may be something silly on my side but can't figure out so far.
Ditto ... I just got my Flex box & remote and discovered the same problem. Checked the Flex FAQs & found nothing that describled the Flex box's operations. Contacted customer support. The agent was sure that the Flex box does turn off via the remote and was sure that I had a defective remote. The agent also told me the obvious that I could unplug the box to power it down. I'd already done out of frustration.
I told the agent that it looks like the box is designed to always remain on. I also told the agent that the power buttom was probably intended to be used when paired with the TV to turn the TV on/off. The brochure that came with the remote does not describe the function of the remote's power button.
It seems to me that having the Flex box always powered up and connected to Xfinity via the internet will up my data usage, even if its minimal.
Also and even though the remote's voice feature is supposed to manual (ie. works only when you press the voice control button), I noticed that the voice control button light routinely flashes as if it was actively listening for a command.
Thanks to the ex-Comcast employee for his insight.
moved entire thread to X1 (set top box Flex related) post.
