As far as I can see, mosquitto by default doesn’t have a config file, you have to create your own. All working fine until I get to the websockets tutorial – the problem being finding examples of a local config file. I’m trying things out on multiple raspberry pi’s with the broker installed on an old Model B running as a nas, then MQTT publishing from a Rpi 400 on the kitchen table (prob not a unique setup). NB the following is probably date specific – 5th March 2021. You should see the message appear in the subscribe window.įirstly, thanks for all this. In the second type mosquitto_pub -h localhost -t test -m message So first open two command prompts in one type.

If you followed the install instructions you will have also installed the mosquitto test clients mosquitto_pub and mosquitto_sub. To start mosquitto using port 1884 use mosquitto -p 1884 Testing the Install To start mosquitto using a test configuration file use mosquitto -c nf The -v option displays verbose logging information other command line options are: Then you can start it using: mosquitto -v #start in verbose mode The first step is to stop mosquitto using: sudo systemctl stop rvice When testing you will find it very useful to run mosquitto manually from the command line.

On the Pi mosquitto can be controlled using the If you need to change the configuration then the configuration file is called nf and is located in the /etc/mosquitto folder. The install installs mosquitto as a service which starts automatically and tuns on port 1883. Then, depending on which version of debian you are using:įor windows and linux see this tutorial on my other site. Mosquitto doesn’t come installed by default so you will need to install it. Mosquitto is a very lightweight broker and a Raspberry Pi can easily cope with MQTT traffic on clients on a smart home networks.
