Some notes I wish existed in my MQTT journey
Mosquitto is a useful messaging protocol which can publish and subscribe messages to various hosts. These messages can be text, sensor data, and all kinds of other things.
mosquitto_sub -h some.host -p 8883 --capath /etc/ssl/certs/ -t "#" -v
$should be hidden from wildcard subscriptions like
mosquitto_pub -t <topic> -r -n
SSL error messages weren't very helpful
Interval 60- required
<LoadPlugin mqtt> Interval 60 </LoadPlugin>
/etc/ssl/certs/ca-certificates.crt-- required if you have a public facing ssl cert
mqtt plugin: Unknown type: "dewpoint".
