The HW-QS90H is new for 2026, an all-in-one 7.1.2-channel bar with thirteen drivers and a built-in quad bass woofer, so there is no separate subwoofer to hide. Its Convertible Fit design and gyro sensor re-map the channels between wall and shelf mounting. Home Assistant control runs through the SmartThings cloud.
Selora does not recommend this device
since September 2026Home Assistant reaches Samsung audio only through the SmartThings cloud API, and Samsung is putting that API behind a paid plan from October 2026, so controlling a bar an installer already fitted turns into a recurring subscription.
Unlike Samsung's televisions, which answer the local samsungtv integration, the soundbars have no local path at all. Free SmartThings API access ends in October 2026: individual developers move to a $4.99/month plan and commercial use moves to separate paid tiers, so a client's soundbar automation comes to depend both on a subscription and on Samsung's cloud staying up. Where a bar is already installed, pair it to the TV over eARC with Q-Symphony and automate the TV's local media_player instead, which keeps evening scenes working with no SmartThings account in the loop.
