Custom ESPHome firmware and Tuya integration

[kincony.com@pagel.info]

if you use ESPHome, we have yaml demo for tuya , but that is only use for KinCony's product.

I have a Kincony A6 for controlling my hybrid heating system. My Warm water boiler is connected via a Tuya smart plug that I want to switch on and off depending on specific usage needs (volumes, temperature, measured by the kincony).
I fould on github the esphome-tuya-iot library but it does not really do what I need.
How ca I use the Tuya API to control from my esphome implementation on the A6 the tuya smart plug? Is there any way to use or tweak the custom_component esphome for this purpose?
