Sorry I took so long to respond. I have been away for a couple of days.
I have attached my configuration file. I wasn’t totally sure what would be needed, so I monitored the OSPi service and the Mosquitto MQtt broker service. I am also monitoring a couple of other Pi’s so I monitor the network by letting them Ping each other. I will probably stop this as I doubt it is necessary. Their addresses were 192.168.0.150 and 192.168.0.58 if you are wondering what those lines are.
