Publish to mqtt with the retain flag?

[bikeymouse]

Hi,

Thanks for your great software. I'm using this to publish the measurements to mqtt which works fine. I only would like to have the messages published with the retain flag set.

In that way the consumers of the data would get the latest state immediately after connecting to my mqtt broker.

Is there a way to configure this?

Ah, I found it: I changed line 136 in mqtt.go from
go m.Publish(topic, false, message)
to
go m.Publish(topic, true, message)

Now the messages are retained ;-)
