Hi @BMS17,
Here's some info about the Roku Smart Light Strip.
Each model comes in two lengths: 16 feet and 32 feet. You can't physically connect different models together, but you can group them in the smart home app. If you have the 32-foot version, you'll get two 16-foot strips. Just connect both strips to the controller, not to each other.

Hope this helps.
