Hi,
as I did not found it in the package list could you please consider to give us the Mosquitto broker program to allow us using (by example) a Raspberry Pi zero as a MQTT broker.
It is particularly usefull in home automation to collect informations on this network by using messages exchanges.
https://mosquitto.org/And if you can also add this light MQTT dashboard named Crouton it could be perfect.
