Hello everyone!
I just published my work on MQTT 
(still building, it will be available in about 1 hour for you)
This brings new features, but it also changes the API. We are still in beta, so I allow myself to « break the API » in the middle, and ask you to make the necessary changes on your side, so that we can move forward and move more and more towards the RC 
The API now looks like this:
Among the new features, the ability to see when the last value was received on each device:
A small UX detail but which is so practical, the ability to copy and paste with one click the MQTT topic on which the device listens/publishes:
I hope you like it, in any case I spent time doing it well on my side!
I am always open to any feedback
