MQTT Client app

[myg]

There is new version in the original post.

Thank you for listening and updating the app. Now the configuration has become much easier with new Json Path setting.
Have you though about improving "Both" 2-way config? I may be mistaken, but i haven't seen any scenario where In and Out topics are the same. 

One more observation: there's a case when i have to copy&paste between many objects: relays. I think there're 2 main devices that produce binary value: contact sensor (it already produces true/false, no need for conversion) and relay which produce on/off. 
When configuring Relay, i always need to add script "return value and 'on' or 'off'", and when converting the other way, usually parse from Json as well. 

Suggestion: if target knx address is a 1 bit object, add drop-down with source value type: Boolean / OnOff, for automatic conversion. Same for Out, if Source is a 1-bit, add the same type of drop-down for target conversion. This way it will be possible to simplify configuration to only Json path and Object type, without need to write script.
