Mqttsend is a little bash and python tool which receives a JSON object over stdin and sends it out over MQTT under the given topic, a configurable username and the current hostname.
- Python3
- paho-mqtt==1.3.0
Make a virtualenv python3 -m venv . and install via pip install -r requirements.txt.
Copy the file config.ini.sample to config.ini and adjust the contents.
Pipe your JSON to mqttsend.sh. That's it!
JSON should contain keys named topic and measurements. It may contain a key named timestamp. If there is none, this tool adds one via utcnow.
