This is my first device type. I decided to puchase a SmartThings hub last week and realized there was no DTH for the greenwave 6 node device. Since I have 5 of these I really needed a handler before being able to implement the hub in my house.
The parent and child DTH can be found below. Make sure to create both handlers from code, save and publish before adding the powernode to your hub. The child devices for each node are created when the device is added to SmarThings, so swapping DTH’s afterwards does not work.
