MQTT Broker is already running 

Can check in the mosquitto.log file and saving memory is stored in mosquitto.db

If you want to set MQTT via Luci Web Install MQTT Luci

root@OpenWrt:~# opkg install luci-app-mosquitto

Refresh Luci web and check in the Services menu mosquitto

Service Mosquitto already installed

If MQTT Broker is already set via WinScp, you don't need to set MQTT via Luci service mosquitto
