Hello everyone, I am having an issue with downlink: I have a UG65 Gateway and a UC100 IoT Controller.I have added them to ChirpStack. On the UC100, I have connected an 8-channel Modbus Relay device to the RS485 port. However, when I send hex code via equeue on ChirpStack to turn the Relay ports on or off, the response is inconsistent: sometimes it executes the relay on/off command immediately, sometimes it takes 5-6 seconds to execute, and other times it does not execute the command at all.

Downlink does not always reach end-device (UC100 + 8-channel Modbus Relay)
