Shelly dimmer gen3

[Henkonoly]

Today I flashed a Shelly dimmer gen3 with Tasmota. I actually assumed the correct template was available for the Gen3 dimmer, but unfortunately it isn't. I used the method below, but the STM32 firmware is not supported. Does anyone have an idea how to get it working properly anyway?

I gues there is not a lot of interest for getting the shelly dimmers working on tasmota.

Maybe i can backup the stock fw of a new one using esptool and flash it back to this one?
