Widgets update with HELLO message

CHE77

When I open app and a board it's widgets have no values. They comes later of course.
IotManager firmware design expecting mqtt message HELLO on topic from root path with prefix. After firmware publish all values at all topics.
Is it possible to automate this at MQTT-Tiles?

I don't know how but another app - MQTT PUSH CLIENT somehow updates all widgets at startup.

Hello. Now you can configure up to 5 Init(Hello) messages for each board.

Great! Thank you. It works!
I am not yet familiar with all possibilities of Tiles.
IotManager replies on HELLO with updated values of widgets and also it sends json with configuration of widgets. If that was a first time widgets will be configured or just updated.

Is it possible to parse coming json and setup widgets accordingly? May be in few steps?
