I have the Roku 4K with IR remote. My wife wants all devices out of sight (behind a cabinet door). I don't want to go through the hassle of setting up an IR extender. Is there an RF remote that will work with this player? Alternatively, do the more advanced players come with RF remotes? I was thinking about the Ultra model to get the USB feature anyway. Would this solve my problem?
What model Roku. You can go to Settings/About to get the exact model number. Many basic Roku models (probably various Express versions) ship with IR remotes, but may work with an RF remote. Most mid and high models come with the RF remote.
The voice remotes are RF-based. You can verify if your original remote is IR by simply covering the front of the remote and seeing if you can control the Roku with it.
Roku 4K with IR remote is likely the Express 4K, model 3940.
Two ways to go:
I went to the products page to find the Voice Remote. When I selected it, the page said "no compatible devices linked to your account". I checked my account info; and it had the Roku 4K Express listed. It sounds like it may be an error on the page; but it also doesn't make sense to buy something when it is telling you it is not compatible.
I think it should be compatible, but I'd also be leery of buying something when it says "no compatible devices". If you post the model number displayed under Settings->System->About @Tivoburkee can probably give you a definitive answer of whether it works.
You may just want to get one at a local store with a good return policy and give it a try.
As far as I know, the only difference between the Express 4K 3940 and the Express 4K+ 3941 is that the 3940 is supplied with the Simple IR remote and the 3941 is supplied with the wifi Voice Remote. The Roku itself is identical and should work with both IR and wifi remotes.
I think the info listed on the Roku comparison page just refers to which remote is supplied with each model, not compatibility information of which remotes will work with each model.
Flagging this to bring it to the attention of Roku employees @RokuDanny-R, @RokuKariza-D, & @RokuMary-F for confirmation of the above.
Meanwhile,@renojim's suggestion of purchasing locally from a retailer with an accommodating return policy is a good one.
