I have a KinCony ESP32 Tuya IoT adapter module. Is there a library you would recommend to use as modbus_switch in home assistant? My aim is to use it as a gateway between home assistant and TUYA. Is it possible?

There are 32 buttons on the KinCony ESP32 Tuya IoT adapter module that we can control from TUYA. I want to introduce them as Home assistanta modbus_switch. It will be as if the module has a virtual relay. When I open switch_1 from Modbus, I will see that it is opened from the TUYA application. The KinCony ESP32 Tuya IoT adapter module already has rs485 hardware. But I am trying to add the modbus code.

do you want to use ESP32 tuya adapter connect to your own relay board by modbus protocol?

ok, you need to modify ESP32 arduino code, replace KinCony's protocol with your board's.

would this be a correct config with 4 A16 boards?
