The Remote Diagnostics Tool gives you the ability to "look inside" your configuration while your display is operating. You can inspect & change the value of numeric and string variables and lists, fire events, and remotely control the button actions and view screen activity. This is a great tool to assist in debugging your configuration and verifying your functions are performing as desired.
This video will demonstrate these features and give you an overview of how to use this tool.
The configuration used in this demonstration was created for a PV1200 in 2.9.23044 and is available for download here: Remote View demonstration Configuration
