DM_WF_MDV4 Dimmer and Case

This is a 240V Leading Edge Dimmer with a TYWE3S controller and an STM8 MCU

Flashing:

The NRST pin of the STM8 needs to be grounded upon boot to disable it, this is brought out to a header pin, along with ground and VCC from the TYWE3S. Confirm by checking continuity with a multimeter

IO0 from the TYWE3s also needs to be grounded upon boot, otherwise it's normal tasmota flashing procedure.
