Sonos bar would be controlled though WiFi so you don’t need to ‘point’ the remote.
Jason DeWitt we just released a new version of Smart Remote software that now allows you to add Sonos Playbar, Playbase, Beam and Amp (added as Wi-Fi devices on Smart Remote) to a TV Scene. Please check out the release notes here.
Would also like this feature. This is how the Harmony remote works.
