First functional version with child device

Responsiveness to update child device using new app
Delays to execute commands using new app (1 to 3 seconds)
Any update to the device handler makes the DoorSense™ unresponsive during the development phase. The reason for it is unknown. When updating the device handler, delete it and create a new one to avoid this issue. This issue somehow affects new installations using github integration

First working version

First working version. Full functionality in new app. State refresh must be tuned
