So I recently added some functionality to a device handler of mine that required several child handlers to be used. I though, “this is going to be a pain for the community to install all of these” (especially if they don’t have github integration setup). So I had a thought that it would be a good idea for community developers to use a common set of child device handlers. At least until SmartThings releases their own. This would make things a lot easier for developers and users utilizing this new functionality. Here is a list with links for all the composite handlers I have created. Anyone is free to use them if they would like as well as add any missing capabilities by posting in this thread.
Child Device Handlers:
Contact Sensor
Metering Switch
Switch
Smoke Alarm
Water Sensor
Carbon Monoxide Sensor
Carbon Dioxide Sensor
Motion Sensor
