WatchMon UDP Binary Listener translates to JSON and stores to influxdb or sends it to MQTT

Getting Started

git clone


npm install watchmonudplistener


Download premade Raspberry PI 3 ISO with everything built in:


MQTT Binary-Parser Influx

How to install them: (If you clone from GitHub)

npm install mqtt
npm install binary-parser
npm install influx


Main install in "Get started"

Start with copying the batrium_config.json_dist to batrium_config.json

Example code in linux:

cp config.json_dist config.json

Edit the file to suit your needs. In the file you have 4 tags for each message:

  • mqtt-> Here you enable or disable if you want a message to be sent to your MQTT brooker

  • Influx -> Enable or disable to send the message to Influx DB. Its not recommended to send more than needed!

  • tag -> Its possible to add tagging to Influx db. Currently run it as is unless you want something special

  • series -> If you want to split out data for instance slow running data from the fast running for easier query in the database this is what you use

The configuration also holds ip/dns for the MQTT brooker and Influx. If you have them on localhost you can leave it as is.

Example config for main setup:

 	"config" : {
                "mqtthost" : "localhost",
                "influxhost" : "localhost",
                "influxdatabase" : "batrium"

Example config for a message:

 "3e5a" : {
             "mqtt" : true,
             "influx" : true,
             "tag" : "general",
             "serie" : "generic"

When you have cloned the git repo and setup the configuration in the configuration files you also need to prepare the database. In the config section you define the influxdatabase and that one need to be created in InfluxDB



then you run: (Change to the database you want to use)

create database batrium 

When all this is done its just a matter of running the application

Automatic startup

cp systemctl/batrium.service /etc/systemd/system/

Be sure to update paths in the file acordingly to where you installed the Batrium UDP listener

systemctl --system daemon-reload

To enable:

systemctl enable batrium.service

To disable

systemctl disable batrium.service
