to be fair, the apple tv remote is fantastic and it's better than any other remote i have used for the common features. (i do wish it had a tv power button though since it can actuate the volume but i guess they wanted to go with the standard that shuts down the tv when you shut off the apple tv if your tv supports it)
Really? The TiVo peanut is still the best I've used. The ability to scrub with the Apple remote is really nice and Siri can be useful but the shape is a disaster and I really miss physical buttons for moving around the interface.
I've got just the apple support document for you! https://support.apple.com/en-us/HT205225 If your TV supports HDMI features you will only ever need one remote.
I have a cheap and old tv that doesn't have that hdmi feature is the problem. to be fair, the tv is kinda off brand and doesn't have any mapping in those "universal" remotes so I have to keep the original remote around if I want to turn it off and on with it. kinda a pain.
If you haven't yet, check your TV settings. My Samsung has a buried option "Auto Turn Off" under HDMI. Disabling this prevents the AppleTV from turning off the TV.
Yes there is you should have HDMI CEC settings somewhere depends on the TV you can set what exactly is passed and is it bi-directional or not.
At the least CEC power is available on virtually every appliance I've seen.
