GE has announced one, but it’s not out yet. There aren’t any others on the market yet.
That said, most people don’t need them because with SmartThings you can take a sensor and place it anywhere and have it trigger any of your controlled light switches. This actually gives you a lot more choice in placement than one that is built into the light switch. You can also take multiple sensors and create a zone so that motion on any of the sensors controls the same light. This is particularly helpful for large rooms or L shaped rooms.
If you really want to have a switch with the sensor built into it, you’ll have to wait for the GE one to come to market, which will probably be a few months.
If you’re willing to use a separate sensor and a switch, you have a lot of choices right now.
