Mqtt and command line

[piheat...@gmail.com]

Hi

I'm hoping someone can offer some help?

I'm running raspbian on a Pi 2 and my broker is mosquito.

To read my current household energy usage I type a command into command line which displays a numerical reply from my energy monitor connected by usb.

Is there a way to publish this reply over mqtt?

Sorry if this is a simple question. I've search the Internet before posting but finding it difficult to find the answer I need.

assuming `energy' is the command you use:

mosquitto_pub -t your/topic -m "$(energy)"

that will republish the stdout produced by `energy' as a payload to the
topic "your/topic".
