Shelly Pro EM3 - not refreshing states via Binding, so i Made my own MQTT integration, lets test it out

Hi
Thanks for sharing your experience.
May you share the mqtt.things and items snippet for EM3 pro if you have text based config, that would be really helpfull.
Mainly sharing all your JSON trasnsforms in items, that would help me get running with MQTT.

You said shelly thread, what is the official one is it this one Shelly Binding ?
Thanks a lot
