COLB integrate to home assistant by mqtt, here is guide: https://www.kincony.com/mqtt-input-modul...stant.html
COLB analog input port for 0-5v

Previously, I was told that it’s possible to convert a 4–20 mA signal for use with the COLB. Could you please explain how to do that? Also, is MQTT integration with Home Assistant possible over Wi-Fi, or is it only supported via Ethernet?

KC868-COLB is 16 channel 0-5v analog input ports, you can convert to 4-20mA, so that can integrate to home assistant by MQTT.
