DM4 ESPHome yaml for home assistant with tuya

[pavel.hajn]

Hello,
is possible to use DM4 with ESPHome and Tuya ? B8M works fine, but DM4 has some trouble in tuya_wifi_mcu_light_output.cpp

Here is the log:

we will test it , then feedback to you. maybe need update tuya component for dimmer board, now the tuya component only use for ON/OFF device.
