Just finished translating the manual I managed to skim for the DC1545V. Wanted to share it here ,might be useful to understand how it works.
I am hoping I can swap the tuya module inside for ESP32Home one. Although seems they moved to new ICs which cant be flashed or directly replaceable in most tuya devices.
Is it worth getting the Zigbee version, I am not planing to integrate Zigbees for now 
Rather was thinking to ESP32Home each dumb-smart device.
