I followed this guide https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-the-mosquitto-mqtt-messaging-broker-on-ubuntu-18-04 and am successfully about to get mqtt messages accross using two ssh windows, however when i run the monitor ([monitor] Reliable, Multi-User, Distributed Bluetooth Occupancy/Presence Detection bash file) command from my rasberry pi and configure it to point to my mqtt server, i dont seem to be seeing any messages when i am running this, mosquitto_sub -h 192.168.1.225 -t test -u “david” -P “Jade2000” (from the monitor/presence detection app)
is there an easy way to test mqtt using the monitor bash script for presence detection?
I have edited the mqtt_preference file to the ubuntu server 192.168.1.225 with the username david and password, if i run this from a separate terminal window on the same server (192.168.1.225), i do indeed get hello world to appear mosquitto_pub -h 192.168.1.225 -t “test” -m “hello world” -u “david” -P “Jade2000”
