Integrate Shelly Dimmer Gen3

Suddenly it was released so i ordered a couple to replace my older (Gen1 and 2) ones that are sort of dying (dropping connection or not responding at all).

Not knowing what i was getting into, i found out that the device isn't as easy as it was before.... so i thought, the functionality "one-button-dimming" for example is kinda hidden, but still there... easily overlooked. I hate that! :lol: :oops:
Anyway, as much as it sounds like a developed new thing, freedom and all what we've ever wanted, my intention is to simply replace the old dimmers. Shelly claims compatibility, but it seems everything but compatible with Domoticz right now.

Maybe someone can point me to some helpfull information since Shelly helpdesk is kinda sad to be honest. I need to integrate the device into domoticz, using MQTT like it worked out of the box in the old days. How do i get it into Domoticz?
I just hope there is some script available to make it work like before, set and go... ?

Use the Shelly teacher script. viewtopic.php?p=322662#p322662
It is not completely gen 3 compatible yet but the can be easily added.

Just installed shellyteacher4domo and ran it... this first resulted in an error for this new device.
So i've created a new entry for the tag [shellydimmerg3] in mqtt_templates_gen2.txt so that it's recognized.
This specific file (mqtt_templates_gen2.txt) inside shellyteacher, takes care of MQTT mapping to allow applications to recognize the unknown hardware.

I am quite stuck with the syntax because i understand *shit* of what i see there... as it is a Gen3 device, things might be different and i don't know how to translate the device payload to a working template. Anyone with some knowlegde on that?

Raised an issue on Github : https://github.com/enesbcs/shellyteacher4domo/issues/65

P.s.: I did manage to get my Shelly 1 Gen 3 to work... the dimmer is just a different thing :|
