So I bought a Ray for my spare room which I’m very pleased with. I found out something interesting today too, after having difficulty pairing the TV remote via the Sonos app. It is a TV remote which had previously failed to work with a Playbase so I wasn’t at all surprised.
I read a review where the reviewer had similar issues pairing his remote, but he found out that his remote uses ‘Toggle Bit’ for its remote controls. In other words, when you hit the same button twice, the remote sends a different signal for each, alternating between two IR codes. So he worked out a work around by following the Sonos setup routine; but after every requested button press, he covered the remote’s IR sensor and hit the button again before continuing with the wizard. So essentially with say the + button, press it aimed at the Ray, then cover sensor with hand and press again, then press again aimed at the Ray, cover and press again, and finally press the last time aiming at the Ray. Repeat then for the - button and the mute button.
He said it worked even though when pressing his remote watching TV, he did have to often press twice for it to register say decreasing the volume or putting it up.
So I went upstairs to try it with my spare room TV and it worked! He is correct that when using the remote with the Ray, a couple of presses are sometimes required, but at least it works
Maybe the community already knows about this work around but for new members this could be very useful.
