2 sensor have output RS485.

I have 2 sensor and the output for communication is RS485. Kincony only have 1 RS485. Can Kincony support 2 sensor at same RS485?

sure, RS485 bus can connect with many device on one bus line.

Do you have an example? i'm using mqtt node red. i'm using KC868 COLB.

i think if your sensor support modbus, you can use Node-Red work with RS485 modbus. we have a video tour , control relay by Modbus, but sensor is same. here is video tour how to use Modbus by Node-Red : https://youtu.be/ogu5JhziUnE

Do you have example code in arduino?

KC868-COLB not made by ESP32, can't use arduino download code.
