As my first project I decided to try and recreate the Hubitat Mirror App and added a few more device types like Motion Sensor, Contact Sensor, Audio and Single Button.
Feedback on any mistakes or general improvements is very welcomed
Here is the repository where you can find the parent and child app:
Excellent work! This is in a similar category to my own Switch Bindings app, but where I focused on two-way binding, you focused on handling lots of device types. I reviewed your code and it looks really clean! (I even learned a couple cool techniques from you.) Congrats on the release!
I actually made a mistake, yet again. It's supposed to be updateAppName("Mirror: ${master}") and the output would be "Mirror: your master device name". without the "" it would just be "Device Mirror Child"
The built in Mirror app only supports Switches (light switches). I extended mine with a few extra devices. I haven't seen the source code for the built in app, but from what I can tell from functionality, the apps behave the same way when it comes to light switches
